Description

The calyx contains the digestive system and is covered by a soft membrane called the tegmen that may be rounded into a mound or look like a drum skin over the calyx; * The anus is also on the upperside, in some species at the top of a cone or tube that brings it above the feeding current to prevent fouling of the feeding process; Feather stars usually have arms in multiples of 5, most have at least 10 arms. Some can have 80-200 arms! mouth faces upwards Ce sont des filtreurs passifs (plancton en suspension) The side of the feather star that faces downwards has a claw-like appendage called the cirri that is used to grip the surface; régénération des bras aisée; pas de plaque madréporique reproduction: dioecism, fécondation externe; Juvenile feather stars start with 5 arms but repeatedly grow back two arms in place of each arm branch that is shed. This branching happens near the calyx.
