Calyx podatypa is a species of sea sponge belonging to the family Phloeodictyidae. It is native to the Caribbean. The species was first described in 1934 by American spongiologist Max Walker de Laubenfels. [1] It is commonly found in shallow reefs, among seagrass and on mangrove roots. It is described as being mostly hollow with growths that ...
Discodermia calyx is a species of bowl-shaped sponge that is found in shallow waters in central and southern Japan. [2] The species is distributed by the central Kuroshio current and is therefore localized along this current. Like many other sponges, D. calyx are very porous. They use the pores in their outer walls to draw in water which they ...
Sea lilies are crinoids with a calyx and five pairs of feather-like arms standing on a long stalk which is retained throughout the animal's life. This stalk is attached to the substrate by means of an enlarged, terminal disc or alternatively by means of several branching, irregular radicular cirri arising from the lowest part of the stem. [3]
In most living species, especially the free-swimming feather stars, the arms branch several more times, producing up to two hundred branches in total. Being jointed, the arms can curl up. They are lined, on either side alternately, by smaller jointed appendages known as "pinnules" which give them their feather-like appearance.
The length of the calyx and stalk are approximately the same. There are 30 to 120 secondary tentacles arranged in clusters at the tip of the arms. Each conad contains 10 to 70 gonadal sacs. This species is commonly mis-recorded as Haliclystus auricula. It was separated from this species in 1997.

Haliclystus antarcticus has a 'stalk' (peduncle) which is a half to two thirds the length of its calyx. The inside of the peduncle is divided into four chambers. The calyx itself is about 3.5–16.2 mm tall and 4.1–23.4 mm wide. It is cone shaped and semi-translucent with a smooth outer surface.
