Scientific Details

Members of this subgenus are characterised by having a uniform mesh size in the outer ectosome. The fibres within the deeper choanosome form a rectangular mesh and are cored by tracts of spicules. There are no free spicules seen in the microscopic sections of these sponges.

Brief species characters:
Growth form: ramose, branching.
Mineral skeleton: siliceous.
Megescleres: monaxone.
Surface texture: porous.

Family level characters:
Most growth forms are represented in this family of sponges including encrusting, massive, vase-shaped, tubular, fan-shaped, plate-like and branching. Species within the family are differentiated by two main features; the reticulation of spicules or mesh type on the surface (ectosome) and the presence or absence of spongin fibres in the internal region of the sponge (choanosome).

Order level characters:
This order contains the greatest biodiversity of sponges with representatives inhabiting all oceans and habitat types, including freshwater bodies, of every continent in the world. Sponges of this order are characterised by a triangular mesh formed by their fibre and/or spicular skeletal elements. This is termed an isodictyal skeleton. The megasclere spicules found in haplosclerid sponges are exclusively oxeas, with either sharply pointed, or rounded (strongylote) ends. Microscleres are present in representatives of only a few genera. Some of the more common marine species are included here.
