Marine Invertebrate Animals Designed to Disperse

The number of marine invertebrate animals is rather startling, and they are found in oceans all over the earth. A key to their dispersion is their larval forms. Like many other living things, the youngest stages are markedly different from their adult forms.

Most of the larvae are microscopic and can live in various conditions. This gives them the ability to travel great distances, often putting full development on hold until the right time. Biblical creationists note that these invertebrates were as diverse before the Genesis Flood as they are today.

Many times, creationists describe the way organisms adapt, grow, and other things to show that they are the products of design, not Darwinism. With marine invertebrate animals, another factor indicates the work of the Master Engineer: ocean currents. The critters are carried through the paths of the sea to all sorts of locations.

Marine invertebrate animals (jellyfish, crabs, snails, etc.) thrive within our global ocean, the largest habitable space on Earth. Their adult forms are commonly found on or within seafloor (benthic) habitats worldwide, from intertidal zones to the deepest plains and trenches that have been explored. It is estimated that these creatures account for more than 92% of marine animal diversity across all major ocean basins. The discovery of such a broad variety and distribution is no mystery: “God blessed them, saying, ‘Be fruitful and multiply, and fill the waters in the seas’” (Genesis 1:22a). In fact, there is ample evidence that many of the adult marine invertebrate forms originally created are still thriving within the world’s ocean today, having endured the Genesis Flood.
