Nudibranchs

There are hordes of predators lurking in oceans around the world, leaving a
trail of slime everywhere they hunt. They seemingly have no fears, even of the
deadliest seafloor creatures. Instead of fleeing in terror from an adversary’s
poison barbs, they calmly steal their prey’s defenses for their own armor, storing
the toxins inside their own skin to frighten other enemies.

They come in all shapes and sizes—some are brightly colored, bold, and flashy,
sporting colorful blue stripes or bright pink polka dots, while others stay
hidden, camouflaged among their surroundings. They can be short or long, round
or flat, bold or subtle, but these real-life monsters aren’t science fiction.
In fact, the tiny nudibranch is one of God’s most common—and beautiful—creatures.

A type of sea slug, nudibranchs (NEW-de-branks) are gastropods, which means
“stomach-foot.” There are more than sixty thousand named species of gastropods
(snails and slugs), and they live everywhere, from land to sea, in almost every climate and habitat, crawling around on
their “foot.” Nudibranchs are just one example of the adaptability of this huge class of animals. More than three
thousand known species of nudibranchs
inhabit oceans and saltwater
seas worldwide, especially warm coastal waters.

What’s in a Name?

The name nudibranch means “naked gill.” While they don’t have gills
like fish, nudibranchs do have exposed tentacle-like bulges on their backs through
which they breathe. They have tiny eyes, embedded in the skin on their backs,
that can discern light and dark, but they get around primarily by feel and smell.
Two horns on their head, known as rhinophores, pick up chemical clues in the
water around them, guiding them to food or other nudibranchs, or warning them
about approaching predators. Sometimes a nudibranch will follow another sea
slug’s slime trail or go the other way if the chemicals in the slime signal
danger.

But why should a humble sea slug have been endowed with such a magnificent
variety of color and beauty? Like the flowers of the field, which were more
splendidly arrayed than King Solomon (Matthew 6:28–29), the nudibranch displays
the glory and creativity of the Designer, whose love for beauty is evident in
His creation. Flaunting bright colors and whimsical patterns, nudibranchs glide
gracefully over the ocean floor, tentacles rippling in the current, a feast
for the eyes, if not for the palate.

Nudibranchs are born with shells, like snails, but shed them as they grow into
adulthood. It might seem foolish to give up their armor, but the nudibranch
enjoys the best of both worlds—in their shell-less state their beauty is revealed
for all to see, and they can deploy more sophisticated weapons. God has equipped
them with some of the weirdest defense mechanisms on the planet.

Look, But Don’t Touch

Some nudibranchs blend into their surroundings using camouflage, while others
sport bright, vivid colors that serve as a warning to would-be predators that
this tasty treat might not be safe to eat. Although this kind of warning is
common in nature (who hasn’t heard of poison dart frogs?), scientists have a
difficult time explaining why conspicuous creatures are less likely to be preyed
upon.

Perhaps the Creator placed in His creatures the instinct to back away from
bright colors and then gave those bright colors to the creatures that would
otherwise be vulnerable. These vivid colors are effective not only as a defense
mechanism but also as a striking example of beauty in creation, providing visual
delight for man, the one earthly creature designed to recognize God’s handiwork
and worship Him for it.

While the vivid colors are sometimes a false alarm, for most nudibranchs the
warning ought to be heeded. Some of them taste foul, and others are inherently
poisonous, releasing an acid when touched or irritated. And as you will see,
others have “stolen” defenses that are downright amazing.

These beautiful colors may
appeal to humans, but they
flash a warning to other sea
creatures: “Don’t eat me!”
Though highly poisonous, the
red-gilled nudibranch wasn’t
born deadly. It eats poisonous
food and stores the poison in
its skin to ward off predators!

You Are What You Eat

You’ve probably heard that you are what you eat (a good reminder to eat healthy
food to have a healthy body), but the nudibranch takes this adage to extremes.

Nudibranchs are carnivores, preying on anemones, sponges, barnacles, other
sea slugs (sometimes even their own species), and other dangerous or toxic prey
that most sea creatures avoid. Then they become what they eat.

Some nudibranchs that feed on jellyfish or anemones, for example, will ingest
the poisonous stingers, but instead of digesting them—and probably dying from
the poison—they will pass the stingers through their gut to the surface of their
skin, storing them in their tentacles, where they are useful for defense.

Evolutionists find the nudibranch difficult to explain. From an evolutionary perspective the creature doesn’t
make sense.

Similarly, other nudibranchs will feed on poisonous sponges and store the poison
in their bodies, ready to sicken anything that eats them. No one knows exactly
how nudibranchs survive ingesting poison or stingers. Scientists believe they
have specially protected cells with thick membranes, but how the process works
is unclear.

Evolutionists find the nudibranch and its thieving ways difficult to explain.
After all, from an evolutionary perspective the creature doesn’t make sense:
its vivid colors are conspicuous to predators, it eats poisonous prey but doesn’t
die, and it somehow borrows the defense mechanisms of the creature it just consumed.
It is difficult to imagine how such a creature could have evolved by chance.

It makes much more sense to believe that the nudibranch was specially designed
by God, who created these incredible creatures with the skills necessary to
survive in a fallen world. Fascinating, beautiful, and quite often deadly, the
nudibranch is one of the most striking examples of our Creator’s creativity
and ingenuity.
