Crinoids are a type of marine animal that belong to a group called echinoderms. Echinoderms include other creatures like starfish and sea urchins. Crinoids are often referred to as "sea lilies" because they have a flower-like appearance.

Crinoids have a long stem or stalk that attaches them to the ocean floor, and they have a body part called a "head" that sits at the top of the stalk. The head has arms or tentacles that spread out like a crown, which is why they are sometimes called "feather stars." These arms have tiny structures called "tube feet" that help the crinoid catch food particles from the water.

Crinoids are fascinating because they are mostly filter feeders. This means they use their arms to capture small organisms and particles floating in the water and then bring them to their mouth to eat. They can also use their arms to help them move around, although they are generally not very fast swimmers.

As creatures belonging to the Triassic, Silurian, and Devonian Period, they are approx. 400 MILLION Years old! 

Fossils have a spiritual significance for transformation, personal growth, and helping one through the process of change. They are spiritually known to instill quality and excellence into one’s environment. 

Overall, crinoids are unique and beautiful creatures that live in our oceans, and they are an important part of the echinoderm family.
