Echidnas Are Extremely Sensitive to Heat

Echidnas Are Extremely Sensitive to Heat

One of the most curious animals on our planet is the short-beaked echidna found in Australia, Tasmania, and New Guinea. This animal is a monotreme, a mammal that lays eggs. The echidna and the duckbill platypus are the best-known animals in this grouping. Echidnas eat ants, so they are also known as spiny anteaters. What you probably don’t know is that echidnas are extremely sensitive to heat. 

An echidna’s body temperature is normally 38 degrees Celsius (100.4 degrees Fahrenheit). If the environmental temperature hits 35 degrees Celsius (95 degrees Fahrenheit), it can be fatal for echidnas. This may sound like an impossible situation since Australia can be very hot, especially in the Dryandra Woodland and Boyagin Nature Reserve. That is where a large echidna population lives about 170 km (105 miles) south of Perth. 

Research published in Biology Letters studied 124 echidnas to see how the animals could handle the heat since they can’t dissipate it by panting, sweating, or licking. The researchers found that echidnas blow bubbles from their noses. The bubbles burst and wet the nose tip. As the moisture evaporates, it cools the animal. The evaporation of water at 100.4 degrees Fahrenheit removes 540 calories per gram of water evaporated. Even though echidnas are extremely sensitive to heat, evaporation protects them from injury.

In addition to the bubble-blowing snout, echidnas have quills to protect them from predators. The echidna’s unique design is very difficult to explain by chance evolution. Instead, God has designed creatures to survive as they deal with the varied conditions around the planet. Everywhere we look, we see that a wonder-working hand has gone before.

Conflict Between Scientific Evidence and the Bible

Conflict Between Scientific Evidence and the Bible- Petrified Forest
For the past two days, we have been reviewing some of the things we saw and learned on the Canyonlands Educational Tour of last month. We explained our approach to the physical evidence of creation and all of the Scriptures that tell what happened. We say that the two sources must agree. If the same God who gave us the Bible also did the creating, they cannot disagree. If there seems to be a conflict between scientific evidence and the Bible, we either have bad science or bad theology or both. And there has been plenty of both.

There has been great conflict between the physical evidence that the Earth is very old and denominational interpretations of the Bible’s creation week. As we visit the Grand Canyon, Bryce Canyon, Zion National Park, the Painted Desert, and the Petrified Forest, the massive amount of evidence that the Earth is much more than 6,000 years old becomes obvious. So how do we resolve this apparent conflict between scientific evidence and the Bible? If we are not locked into those denominational belief systems, we can take the Bible literally. By that we mean, look at who wrote it, to whom they wrote it, why they wrote it, and how the people it was written to would have understood it.

Genesis was written in the style of Hebrew poetry to all of humanity–those living in the days of Moses as well as those living in the 21st century. We cannot expect the account to deal with quantum mechanics, because the people of Moses’ day would not have understood it. The animals described in Genesis are animals that people of Moses’ day would know. Don’t look for duckbilled platypuses, echidnas, penguins, or dinosaurs in the Genesis account. Don’t look for descriptions of stellar production of heavy elements or evolution of stars or even continental drift.

We could list hundreds of things that you would not expect in the biblical account because the ancient Israelites would have no way to understand them. Furthermore, there would be no reason to give such details, and the Bible would be too heavy to carry. For that reason, the Bible begins with the single sentence: “In the beginning, God created the heavens and the earth.” That sentence prepares the reader for a simplified description of the actual production of humans and their domesticated animals on the planet we call home. There is no conflict between scientific evidence and the Bible when taken literally. We will have more on that tomorrow.

Earth Movers

Echidna
Echidna

They are designed to move dirt. The echidna is one of only two mammals that lay eggs. (The other is the duckbilled platypus.) Every year the short-beaked echidna (Tachyglossus aculeatus), lays one leathery egg which is about the size of a grape. The egg is put into the mother’s pouch, and it hatches in about ten days. Two patches of pores in the pouch ooze milk and the baby, which is called a puggle, laps the milk from the mother’s skin. The baby hangs on to the mother for weeks as she forages. When it the starts growing spines, the mother will put the puggle into a burrow, and it is on its own.

Echidnas get their food by clawing and poking their snouts into termite hills or ant nests. They flick out their sticky tongues and draw in the insects. The echidnas’ toes point backward on their hind legs and forward on the front. Their short legs slant outward, and they move both left feet at once and then both right feet at once, so they rock as they walk. They may look awkward while walking, but they are well-designed to move dirt. Echidnas spend 12% of their day excavating so that in a single year each echidna will churn up 204 cubic meters of soil. That’s enough to bury 100 full sized refrigerators.

Turning over the soil mixes nutrients and aerates the soil to benefit the Australian ecosystem in which the echidna lives. The echidna improves the soil while removing ants and termites making this animal an important part of God’s design for this planet. Everywhere we look we see testimony to the wisdom of God.
