Hamacantha

Hamacantha is a genus of sponges in the family Hamacanthidae. This species in this genus differ from those in the other genera in this family through the presence of diancistras, distinctive microscleres. These are thought to aid in framing the skeleton by joining monactine megascleres. This genus contains 30 species in three subgenera.

Hamacantha is a genus of sponges in the family Hamacanthidae. This species in this genus differ from those in the other genera in this family through the presence of diancistras, distinctive microscleres.2 These are thought to aid in framing the skeleton by joining monactine megascleres (that is megascleres that grow in only a single direction).3 This genus contains 30 species in three subgenera.4
