FEATHER STAR Meaning and
Definition
-
A feather star is a marine invertebrate belonging to the class Crinoidea, characterized by its graceful and delicate appearance resembling a feather or bouquet of flowers. Also known as crinoids, feather stars consist of a central body, known as the calyx, from which flexible, feathery arms extend in a radial pattern. These arms possess numerous slender appendages known as pinnules, giving them their distinctively feather-like appearance.
Feather stars are found in various marine environments, such as tropical reefs and deep ocean floors, attached to rocks or other substrates by a stalk or by clinging onto coral structures. They have the ability to move and change their position using their numerous jointed arms and feather-like extensions, allowing them to feed while perched or crawl across the seabed.
Feather stars are filter feeders, utilizing their feathery arms to capture tiny plankton and organic particles from the water. They possess a unique feeding mechanism, in which tube feet called tube dwellers line the pinnules, assisting in capturing prey. These tube feet transport captured food particles to the mouth located at the center of the calyx.
With their vibrant colors and intricate patterns, feather stars are not only fascinating to observe but also contribute to the biodiversity of marine ecosystems. They are often admired for their beauty and are a popular subject of study in marine biology due to their complex anatomy and ecological significance.

Etymology of FEATHER STAR
The word "feather star" is a combination of two terms: "feather" and "star".
The term "feather" refers to the long, delicate, and feathery appendages that give feather stars their distinctive appearance. These appendages, known as "arms", are covered with small, comb-like structures called "pinnules", which resemble feathers.
The term "star" is used because feather stars belong to a group of marine invertebrates called "crinoids", which are related to starfish. Crinoids have a central body, known as a "calyx", from which the feathery arms radiate, somewhat resembling the appearance of a star.
So, the combination of "feather" and "star" accurately describes the physical characteristics of these organisms, which are marine animals classified under the class Crinoidea.
