bioluminescent Archives - DOES GOD EXIST? TODAY

Several Bible passages encourage us to look at the creation around us and know there is a God by what He has made. Romans 1:20 says, “For the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and divine nature have been clearly seen being understood from what has been made, so that men are without excuse.” We can see the power and nature of God by looking at the things in the natural world all around us. One of those things is squid communication by bioluminescence.

Humboldt squid (Dosidicus gigas) living 1500 feet (457 m) below the ocean’s surface in total darkness hunt for food in groups. These are big animals averaging six feet (1.8 m) long, but they don’t bump into each other. Recent research has shown that Humboldt squid use squid communication by bioluminescence. The squid have small light-producing organs in their muscle tissue, and they can convey information by changing the pigmentation pattern.

Scientists from Stanford University and the Monterey Bay Aquarium Research Institute say that what these squid do is similar to humans using turn signals in traffic. But even more than that, they can use changes in pigmentation patterns in a way similar to how humans arrange words in a sentence. Ben Buford of Stanford says that this is an example of a complicated form of animal communication never seen before in deep-sea creatures.

The more we learn about creation, the more we see complexity and design that speaks of a Creator who built into every animal the tools for survival. Squid communication by bioluminescence is just one more evidence of design. Indeed we can know there is a God through the things He has made.

More than a mile (2250 meters) below the ocean, there is a world of darkness. Finding a mate in that dark place could be a challenge, but a species of anglerfish with the scientific name Haplophryne mollis has the problem solved. The solution is to keep your mate permanently attached. The so-called ghostly seadevil finds a mate in the dark and doesn’t let go.

The female sends out pheromones, chemicals which attract the males. The males, which are much smaller than the females, have a keen sense of smell to detect the pheromones in the water. Ghostly seadevils are called anglerfish because they have a “fishing lure” in front of their face to attract other fish which they eat. In the case of the ghostly seadevil, only the female has the lure, and it’s bioluminescent, meaning that it glows in the dark.

Once the male has detected the pheromone, he looks for the glowing lure. He examines the shape, color pattern, and flash pattern of the lure to tell if this is a female of his same species. If it is, he clamps onto her with his teeth and doesn’t let go. Eventually, their skin grows together, and their blood vessels join. She provides his nourishment, and he fertilizes the eggs which she lays. The eggs float upward to the ocean’s surface where they hatch, and the larvae feed on plankton. As they mature, the seadevils migrate back down into the ocean depths and repeat the cycle of life.

This is a drawing because pictures are hard to get in the dark ocean. In this case, you can see that two males have attached themselves. You can also see the bioluminescent lure on the front of the female fish’s head, and that’s how the ghostly seadevil finds a mate in the dark. They have a “ghostly” appearance because their bodies are translucent like many creatures living in darkness. This cycle of life seems strange, but it has too many coincidences to be accidental. We think it shows the creativity of the God who designed life to survive everywhere on Earth.
