Chondrilla nucula, sometimes called the Caribbean chicken-liver sponge, is a species of sea sponge belonging to the family Chondrillidae. It is an amorphous shaped sponge that grows in flat, sometimes bulbous sheets in benthic communities. It is sometimes found in marginal, stressful systems such as caves.

Chondrilla nucula (Schmidt 1862) Small brown lumps, usually with paired pores, colonies rarely exceeding about 10 cm across. The surface is smooth and sometimes shiny. The common name of ’chicken liver sponge’ describes its appearance and texture. The sponge apparently can hang from ceilings, stretching itself as a means to disperse (see photo).
