World’s Deepest Diving Mammal

Worlds Deepest Diving Mammal Recent studies of the Cuvier’s beaked whale, also known as the goose-beaked whale, have established that it is the world’s deepest diving mammal.

Cuvier’s beaked whales dive to feed on squid and fish near the ocean floor. Researchers monitored the whales diving as deep as 2993 meters (about 1.9 miles) and staying down for more than two hours. The mean depth of the deep dives was 1400 meters for more than an hour. For example, the pressure on the whale’s body at 1800 meters (almost 6,000 feet) is 2,600 pounds per square inch (17,926 kPa). Human divers can only stand about 173 pounds per square inch (1196 kPa), which is a depth of 400 feet (122 m).

On average, these whales hold their breath for over an hour, and yet when they return to the surface, they can be ready for a shallow dive again in as little as two minutes. They tend to alternate between shallow and deep dives with the average time between deep dives being about 100 minutes. The design of the whale’s body that allows survival in these extreme environmental conditions is a subject of scientific research.

There is also the question of why they go to such extremes when the same food is available closer to the surface. One interesting aspect of the behaviors of all animals is their role in maintaining balance in the ecosystem. Like all other environments, the deep ocean needs predators to keep a balance between deep ocean life-forms and their food supply. As science begins to explore the deepest parts of the ocean, we see that there is a whole ecology that keeps life in balance. Cuvier’s beaked whale, the world’s deepest diving mammal, is part of that designed system which indicates a Designer.

Facts About Plant Design

Facts About Plant Design including Watermelon One of our gardener friends sent us these interesting facts about plant design:

Seeds may be dropped into the ground upside down or sideways, yet the plants always come up to the surface.

One grain of corn will produce a stalk on which there may be two ears, with perhaps 742 grains on each ear.

A light crop of wheat will produce approximately 30 grains on each stalk. A good crop of wheat will produce approximately 60 grains on each stalk. There will always be an even number of grains.

Beans grow up a pole from left to right. Morning glories grow up a pole from right to left. If turned upside down, “twining” plants will uncoil and recircle their support. Guide a twiner in the “wrong” direction, and the plant will rewind itself. The higher the twiner grows, the more tightly it clasps its support.

Dandelions will grow above their surroundings whether the grass is two, ten, or twenty inches, for it must grow up into the sunlight.

An average watermelon will have ten stripes on it. Larger ones may have 12 to 16 stripes, but they always an even number.

Those are just a few facts about plant design. Every form of life in the vegetable and animal kingdom has a predetermined set of characteristics – a master plan perfect in every detail – God’s plan. God has a perfect plan for my life and yours, which supplies all our needs – His Word (2 Peter 1:3). By His grace, we receive strength to rise above all our circumstances (Romans 8:31).

Cryptobenthic Fish and Coral Reefs

Cryptobenthic Fish and Coral Reefs Those of us who have spent many happy hours snorkeling in coral reefs tend to look at the big fish that we see in the reef. Groupers, sharks, rays, and parrotfish attract our attention. We can easily miss what makes the reef ecosystem work so that the larger fish can live there. Scientists are learning about cryptobenthic fish in the coral reefs.

Hanging around the reefs are tiny fish that are less than five centimeters long and easily escape our attention. They are known as cryptobenthic fish, and they exist in various species, some of which are known as blennies and gobies. Large numbers of them live in the rocks and crevices, and many of them are nocturnal.

Science News (June 22, 2019) reported on a recent study by scientists from Simon Fraser University in Canada. The study shows that these small fish provide a base to the food chain and allow the larger fish to survive. They don’t venture far from the corals that are attached to the floor of the reef. The cryptobenthic species include 17 families of fish that scientists have identified so far. Researchers in the past have overlooked most of them. Deron Burkepile, an ecologist at the University of California at Santa Barbara, says: “Their role is extremely important. We have definitely overlooked these little cryptobenthic species.”

As we look for the design features that God has built into every ecosystem on Earth, we find complexity and sophistication, allowing the system to function. New studies of the tiny cryptobenthic fish in coral reefs will tell us a great deal about the complexity of the reefs and what makes them work.

Snake Charmers, Monsters, Hoaxes

A group of college students and I were discussing UFOs, the Loch Ness Monster, and the snake charmers of India. One young lady who had been very quiet finally spoke to another student who had not participated in the discussion and said, “And what have you substituted for God?” The stunned silence of the group demonstrated the perceptive nature of the question, which effectively ended the discussion. Snake charmers, monsters, hoaxes, and other deceptions are not a substitute for God.

Many Americans seem to be “turned off” by religion. They have seen so many frauds, rip-offs, and totally dishonest approaches that they have rejected the whole concept of God. As a substitute for God, they have accepted a variety of things. Some have embraced the idea that aliens from space are their only hope of immortality. Some have embraced the Eastern religions and philosophies such as Hinduism, Buddhism, Bahai, and Islam.

One of the approaches of those who attempt to convince us to follow their beliefs is to astound us with “mystic” demonstrations. We have all seen pictures and videos of snake charmers who play a long flute as a great cobra sways back and forth. This is one of the oldest of all hoaxes dating back to at least 300 B.C. Snakes do not have ears, so obviously they don’t respond to the music which is for the crowd’s benefit. The flute is then lowered over the snake’s head so that when the charmer blows, the wind continues to arouse the snake to follow the motion of the pipe. Snake charmers often make a small incision in the face of the snake to cut the ducts leading to the fangs. Then even if the snake bites the charmer, its bite will not be lethal.

How do people walk on beds of coals, run skewers through their cheeks, and lay down on beds of nails? Studies by anthropologists have discovered two factors. One is the extensive preparation of the skin by rubbing, sanding, scraping, and other techniques that make huge callouses. The second is the use of drugs which not only kill pain but may also affect blood flow and body temperature. Medical science has had an interest in those drugs for use in modern medicine.

What about monsters? Whether it’s Nessie, Bigfoot, Yeti, or giants, all attempts to prove the existence of monsters of any kind end in failure. The critical thing to remember is that snake charmers, monsters, hoaxes, and other deceptions are out there. People are giving up God and accepting false money-making tricks. We should embrace the Bible as our source of truth and Jesus Christ as Lord without allowing anyone to mislead us. Every shred of evidence we have proves the Bible to be trustworthy, and those other claims to be false.

Do not allow human trickery to mislead you religiously or otherwise. “Work out your own salvation with fear and trembling” (Philippians 2:12) from God’s Word. Salvation is free and available to anyone. The bottom line is beware of snake charmers, monsters, hoaxes, and other deceptions. Use your God-given intelligence to investigate all claims, and you will find truth in Christianity, not the tricks of men.

Zoopharmacognosy Animal Doctors

Zoopharmacognosy Animal Doctors Zoopharmacognosy is a word you don’t see every day. It’s actually a combination of three Greek words which mean “animal” (zoo), “drug” (pharma), and “knowing” (gnosy). It refers to animals using plants, soils, insects, or drugs to solve specific medical problems. It is animals (not humans) medicating themselves. Mammals, birds, and even insects use zoopharmacognosy to cure medical problems, and sometimes to prevent them. Here are a few examples.

It is fairly common to see a sick dog or cat eating grass to induce vomiting.

Sick chimpanzees swallow bitter leaves of Aspilia, a plant that contains an anti-parasitic chemical. The leaves are covered with bristles and bitter tasting so the chimps roll up the leaves and swallow them whole like we might take a pill.

Others chimps and bonobos with diarrhea will split open the stem of an Aframomum plant and suck the bitter juice. The juice contains chemicals which kill parasites which cause diarrhea.

Spider monkeys in Brazil have been seen eating seed pods from a tree known as monkey ear or elephant ear (Enterolobium cyclocarpum) during mating season. The fruit contains progesterone which promotes female fertility.

Brown bears make a paste from the chewed roots of osha (Ligusticum porteri) mixed with saliva and rub it into their fur to repel insects and soothe the bites. The plant contains coumarins which repel fleas and ticks.

To get rid of lice, many songbirds with put ants on their feathers or even roll in an anthill. The ants secrete formic acid, which kills feather lice.

Ants infected with Beauveria bassiana, a soil fungus, will eat harmful substances that are antifungal.

Many kinds of animals will eat dirt to absorb toxins, to combat parasites, or as an antacid. Sometimes they eat dirt to supplement minerals that are missing in their diet.

Pregnant elephants will chew the leaves of a specific tree in the Boraginaceae family to induce labor. Kenyan women make tea from those leaves to help with childbirth. In many cases, people have learned medicines and tonics from animals.

There are many more examples of zoopharmacognosy in which animals act as their own doctors. How did animals get this knowledge? It seems to be instinctive, not learned. Perhaps this instinct was put within the genetic code of these animals by their Creator.

Saguaro Desert Old-Timers

The saguaro (pronounced suh-wah-roh) cactus is found only in the Sonoran Desert areas of southern Arizona, northern Mexico, and a small area of southeast California. We call them saguaro desert old-timers for a good reason. Saguaros grow very slowly as a single stem for perhaps 75 years before developing arms. Plants with five arms may be 200 years old.

Saguaro flowers bloom at night from April to June. They close by noon the next day, never to open again. Saguaro flowers can only be fertilized by cross-pollination so there must be a creature to carry pollen from one plant to another. Because the flowers bloom at night, bats are the pollinators. They drink the nectar and transfer pollen from plant to plant.

A successfully pollinated flower will produce a green, oval-shaped fruit with bright red pulp. Many desert creatures eat the fruit and aid the saguaros by spreading their seeds. Only a small percentage of the seeds will ever germinate, but that’s okay because each flower produces as many as 4000 seeds.

Not only do the saguaros have a symbiotic relationship with the bats which consume their nectar and the many creatures who consume its fruit, but it also provides shelter for many desert animals. Saguaros become apartment houses for birds, lizards, desert rodents, and reptiles, as well as a whole entourage of insects.

Saguaros are remarkably well-designed for life in a dry climate. The outside of the plant has pleats like an accordion. The pleats allow expansion for storing large quantities of water when the rains come. As with other cacti, the saguaro has needles rather than leaves to reduce the loss of moisture by transpiration.

Saguaro desert old-timers are designed in a marvelous way to live in the harsh conditions of the desert while providing food and shelter for various desert creatures. They are another indication of a Master Designer of life.

Romantic Get-Away Inside a Sponge

Venus flower basket
The Venus’ flower basket (Euplectella aspergillum) is a deep ocean sponge with fascinating properties and an unusual symbiotic relationship with a pair of crustaceans. We call it a romantic get-away inside a sponge.

The Venus’ flower basket is classified as a glass sponge because its body is made of silica, which is chemically the same as glass. The silica fibers are woven together to make a hollow, cylindrical vase-like structure. The fibers form a fine mesh which is rigid and strong enough to survive deep underwater. The picture shows a Venus’ flower basket more than 8400 feet (2572 meters) under the ocean’s surface.

Glassy fibers thin as a human hair but more flexible and sturdier than human-made optical fibers attach the sponge to the ocean floor. The sponge forms the fibers at ocean temperatures while human-made glass fibers require high-temperature furnaces to melt the glass. Human-made fibers are brittle while the sponge’s fibers are more flexible. Scientists are studying these sponges to find ways to make better fiber-optic cables.

We think it’s amazing that the Venus’ flower basket lights its fibers using bioluminescence to attract prey. Even more interesting to us is the symbiotic relationship these sponges have with some crustaceans called Stenopodidea. The Venus’ flower basket holds captive two of those small shrimp-like creatures, one male and one female, inside the sponge’s hollow mesh tube. The captive creatures clean the flower basket by eating the tiny organisms attracted by the sponge’s light and consume any waste the sponge leaves. The sponge provides the crustaceans with protection from predators.

As the crustaceans spawn, their offspring are small enough to escape from the basket and find their own sponge-home where they grow until they are trapped. Because a pair of crustaceans spend their lives together inside the sponge, Asian cultures sometimes use a dried Venus’ flower basket as a wedding gift to symbolize “till death do us part.”

The Venus’ flower basket and the crustaceans benefit each other by mutual cooperation, which we call symbiosis. One more thing, the bioluminescence comes from bacteria that the sponge collects. This amazing three-way partnership occurs deep under the ocean where humans have only recently explored. We think this romantic get-away inside a sponge is another evidence of Divine design, not chance mutations.

Unique Spiders with Amazing Speed

Unique Spiders with Amazing Speed One of the evidences for God is the specialized design features built into living organisms. There are indications of design and intelligence that are difficult, if not impossible, to explain by chance. There are about 35,000 named species of spiders, but scientists are still discovering more unique spiders.

Spiders have many features that allow them to provide balance in the natural world by eating insects which would otherwise pose a threat to all life on Earth. Spiders capture their prey in various ways. We usually think of spiders making webs. Most of them do, but not all. Many unique spiders use other tactics to grab insects, while the ones that make webs use a variety of shapes and patterns in a variety of locations. Even the way they use their webs varies.

One family of spiders called ray spiders (Theridiosomatidae) make cone-shaped webs. But even ray spiders don’t all use their cone-shaped webs in the same way. In the Peruvian Amazon, there is a ray spider that weaves a cone and attaches a single strand of silk to its tip. The spider reels in the strand to put tension on the web. Instead of waiting for an insect to fly into the web, this spider takes a more proactive approach. When an insect flies in front of the cone, the spider releases the single strand. With the tension released, the web shoots out with the spider riding the tip of it like a slingshot. The helpless insect gets nabbed in mid-air. For obvious reasons, this spider is called the slingshot spider.

The tip of the cone with the spider attached reaches the target with amazing speed before the insect can escape. Scientists have measured the acceleration of the spider riding the slingshot at 100 times the acceleration of a cheetah, the fastest land animal on the planet. As far as unique spiders, we believe that the slingshot spider holds the title of world’s fastest spider.

This spider creates a very complex and well-designed food-collecting tool. The spider must make the cone in exactly the right shape, and with the right chemical make up of the strands for elasticity. Who taught the slingshot spider this amazing trick and gave it the physiology needed to carry it out? We see God’s design and chemistry in everything from the atom to the universe to every living thing on Earth, including unique spiders.

Half-Slumber Design in Animals

Half-Slumber Design in Animals We have a clock in our brain that is based on circadian rhythms. The clock is connected to Earth’s rotation, and it provides daily periods of rest and recovery called sleep. Animals have it too, and for many animals, sleep is a dangerous time if there are predators around. Scientists have discovered that many animals, especially marine mammals, have a half-slumber system designed to keep them safe and yet allow them to sleep.

The half-slumber system allows half of the brain to sleep while the other half is awake and able to respond to danger or navigational needs. Studies in dolphins have shown that there are different regions of the brain that work together to allow one side of the brain to function while the other side sleeps. The hypothalamus contains ventrolateral preoptic nuclei that exchange messages between the left and the right sides of the brain. They determine which side sleeps and which side remains alert to danger. This also allows movement of the dolphin’s fins and tails to generate body heat in the coolness of the marine environment. It also allows the animal to surface, to breath, and to swim with its companions.

Northern fur seals have a similar system but highly modified. The fur seals come out on land and assume a posture that allows them to put one flipper in the water which they paddle with while keeping the other three flippers in the air to avoid heat loss. Their nostrils are out of the water, allowing breathing and one eye is open and looking for predators. The part of the seal’s brain that provides vision is not connected to the other functions of breathing or movement.

Birds also use the half-slumber design. Mallard ducks have a unique system where the ducks form a group. Ducks on the outside of the group have one eye open, and their brains function differently than ducks at the center of the group. Migrating birds that fly for very long times also use the half-slumber design with one eye and one side of the brain watching where the bird is going while the other side of the brain slumbers. Great frigate birds fly for ten days at a time using this system. Swainson’s thrush gets its sleep by taking micro naps when it is perched.

It seems that every creature using the half-slumber design to get its required sleep uses it differently. The changes are not small and are highly complex involving many organs. Intricate design differences in the brain primarily direct them. Studies of animal sleep are in an early stage, but the complexity of the system is undeniable. The Bible tells us that we can “know there is a God through the things He has made” (Romans 1:18-20). It is a very difficult challenge to understand just how complicated God’s design is. Even in our sleep, we demonstrate God’s plans and engineering.

Cat Tongues and Papillae

Cat Tongues and Papillae Alexis Noel and David Hu have been researching cat tongues as reported in the Proceedings of the National Academy of Sciences (December 2018). Using 3-D scanning with micro-computed tomography, they have discovered some interesting things.

The backward facing barbs (papillae) on cat tongues are not cones as had been previously thought. They are actually hollow structures similar to scoops for dipping ice cream. They have a U-shaped cavity that holds fluids extremely well. This shape enables cats to use the force of surface tension to pull up water as they lap it. It also allows them to wick saliva deep into their fur. When cats lick themselves, saliva is distributed all the way down to the roots of the hairs. Cats don’t have sweat glands except on their paws, so the distribution of saliva removes heat from their skin.

The papillae also allow cats to lick up oils and other contaminants on their fur. This not only keeps the cat clean, but it avoids odors. Applying this discovery may open the door to a whole new line of materials for use in home and industry. Dr. Noel gives one word of warning. Don’t let your cat lick a microfiber blanket, because the cat’s tongue will stick to the blanket!

Cat tongues are not like sandpaper but rather like Velcro. Velcro was discovered by scientists watching other examples in the natural world. Humans have copied the design of materials found in living organisms to create many of the substances we take for granted. We see God’s creative genius everywhere we look. “We can know there is a God through the things He has made” (Romans 1:19-20).
