The Mediterranean Feather Star (Antedon mediterranea) is a marine (saltwater) crinoid in the Antedonidae family of unstalked feather starfish.
The Mediterranean Feather Star can be a range of colours, such as white, yellow, orange, red, deep purple, and brown. It has a calyx – a small cup-shaped structure that is surrounded by five pairs of feathery arms. These 10 arms have 40 grasping cirri which are curl-like tufts, feathers, or fringes. The arms are like tentacles. The arms are prehensile, which means that they can grasp objects, food, and hard surfaces. In danger, the arms can roll up. The arms are fragile, but they can regenerate (re-grow) if they break off.Continue reading “Mediterranean Feather Star”
