#echinoids — Public Fediverse posts

The Eccentric Sand Dollar (Dendraster excentricus) is a cousin of sea urchins and sea cucumbers. It uses tiny spines to scoot along or burrow into the sand. The photo shows its exoskeleton — the smooth, patterned “shell” you might find washed up on the beach.

"ecosystems of the deep sea have emerged again and again after multiple #MassExtinctions... But there is increasing evidence that parts are much older. A team has now provided the first #fossil evidence for a stable colonization of the deep sea floor by #invertebrates for at least 104 million years."
