Psalm 104:24-25: Biodiversity, with Echinoderms (starfish and their relatives)

Biodiversity poster, Psalm 104: brittle star and sponge
The animals in the picture above are brittle stars, a member of the same phylum as starfish, sea urchins, and others, and a sponge, also an animal. Echinoderms, among other oddities, have five-fold symmetry. The graphic serves as a link to a Flickr picture, which, among other information, has the credit for the original photo. (Altered and posted with permission of the underwater photographer.)

Here's an amazing video, less than three minutes, from the BBC, showing starfish (also known as sea stars), Nemertean worms, and sea urchins, swarming around a dead seal pup, off the coast of Antarctica.

I thank a friend who looked at one of the previous posts in this series for the tip on this video.

Thanks for looking and reading.
