View scientific description and taxonomy

Scientific Details

These fistulose sponges are characterised by their possession of elongate, rod-shaped microxea microscleres with diamond-shaped tips.

Brief species characters:
Growth form: bladder-like.
Mineral skeleton: siliceous.
Megescleres: monaxone.
Surface texture: fistulose.

Family level characters:
Many of the species in this family take burrowing, excavating or encrusting forms with protruding fistules.

Order level characters:
This order contains the highest diversity of sponge species in the phylum, spread amongst 25 families. 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.
