Abstract

Tetillidae Sollas (Demospongiae, Spirophorida) are for the most part globular sponges (‘golf ball’ sponges) belonging to a small order on account of their possession of sigmaspire microscleres and triaene megascleres. The characteristic megasclere is the protriaene, which is found in most members of the family with very few exceptions. In addition there are long oxeas and frequently anatriaenes, rarely also calthrops or amphitriaenes. The skeletal architecture is strictly radial. Eight valid genera are recognized, differentiated by presence of cortical structures, specialized pore-sieves, and composition of the spicule complement. Tetillids are common and ubiquitous sponges in all oceans and at all depths.
