Scientific Details

This cosmopolitan sponge genus contains many species which may be massive, lobate or fan-shaped, typically with an irregular surface. The species shown is thickly encrusting to conical.

Brief species characters:
Growth form: volcano.
Mineral skeleton: siliceous.
Megescleres: monaxone.
Surface texture: lumpy, oscules apical.

Family level characters:
Members of this family adopt various growth forms from massive to encrusting, branching or as hollow tubes (fistulose). The seven genera in this family are grouped together because of the similarities in their mesh-like skeletal structure and the combinations of spicules, which include rod-shaped megascleres with slightly swollen ends (tylotes) in the outer layer and the claw-like microscleres, chelae.

Order level characters:
This order contains the highest diversity of sponge species in the phylum, spread amongst 25 families. Member species have been recorded from all marine habitats. Poecilosclerid sponges are characterised by the presence of both organic (fibre) and inorganic (spicular) skeletal components, both usually well developed. Different spicule and skeletal elements are often localised to particular regions of the sponge. A diverse range of spicule types is displayed throughout this order including the c-shaped chelae microscleres that are peculiar to this order. Examples from 11 of the 25 families are included here.
