sea lilies
Feathery ocean invertebrates
Sea lilies are marine animals that resemble flowers, with feathery arms radiating from a cup-shaped body atop a long stalk anchored to the seafloor.
Despite their plant-like appearance, they're echinoderms—relatives of starfish and sea urchins.
Most species live in deep water.
The unstalked forms are called feather stars.
