Scientific Details

This pale orange species species is from the subgenus Arenochalina, sponges that characteristically incorporate sand and foreign material and/or filamentous algae into their fibre skeletons.

Brief species characters:
Growth form: encrusting.
Mineral skeleton: siliceous.
Megescleres: monaxone.
Surface texture: velvety, oscules prominent.

Family level characters:
Sponges in this family may also be encrusting, massive, branching or fan-shaped but the species treated here are restricted to those having a combination of two features; a surface skeleton of spicules lying parallel or tangential to the surface of the sponge, and possession of asymmetrical chelate microscleres, known as anisochelae. Superficial sculpturing of these sponges is often visible through the transparent surface in the form of grooves and ridges.

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.
