It is defined as a genus of the family Cheloniidae of sponges that contains the finger sponge and the dead-man's-fingers. It has perforations all over its body and thus gives a honeycomb appearance. Mermaid’s glove is the common name of Haliclona oculata. The Chalina is generally called the Finger sponge since it looks like the fingers in our hand.
