Look at me and these grey beebs. One is an African Grey, and I think the other is a ringneck.
Crinoids are really cool creatures! They’re marine organisms and they live anywhere from colorful coral reefs to deep, dark benthic zones. Though they resemble plants, they’re actually animals, much like anemones and sea sponges, meaning they don’t photosynthesize so they have to catch food for themselves. They do this using the long, frilly tendrils that are rooted around their mouth (and most of their other internal organs). They can manipulate these tentacles to draw little bits of food floating by into their mouths.
Most crinoids living today resemble the first two pictures; they look like big clusters of tentacles rooted in place on a rock. These are commonly called “feather stars,” since they are echinoderms, which means they are closely related to starfish. Crinoids possess the same fivefold symmetry as starfish, though it’s hard to tell due to the mess of tendrils.
But there are a few species of crinoids with long stalks that separate their bodies from their roots. These are called “sea lilies” and they are found in the deeper depths of the ocean, which is why they are more rarely seen. The third picture is one such sea lily.
Perhaps the most interesting feature about these creatures is their movement. Most of the time, crinoids will stay in place, content to gather food in a safe spot. But if threatened, they can detach themselves and just swim away! In fact, some sea lilies have even been observed crawling across the ocean floor! This is very different from similar-looking creatures like anemones and sponges, which usually stay rooted in place for life.
This behavior hearkens back to prehistoric times, when crinoids were much more widespread. Back then, crinoids were more mobile and more capable of escaping predators, and the long-stemmed sea lily-style crinoids were more common (fourth image).
Though these creatures are relatively obscure to most people, they inspired the designs of Lileep and Cradily, two fossil pokemon which are also my personal favorites. To learn more about that, check out this wonderful article.

I was bored so I got out my saxophone and took about ten minutes to figure out the notes to this. My favorite song from Mario Kart 8.
