Chondrocladia concrescens

Chondrocladia concrescens (formerly Cladorhiza concrescens), is a carnivorous sponge in the family Cladorhizidae. It is thought that the object known as the Eltanin Antenna may be an individual of this species.[2] Alexander Agassiz described the sponges as having "a long stem ending in ramifying roots, sunk deeply into the mud. The stem has nodes with four to six club-like appendages. They evidently cover like bushes extensive tracts of the bottom."[3]
