Description

Genus Grantia Fleming, 1828

TYPE SPECIES. — Spongia compressa Fabricius, 1780 by original designation.

DIAGNOSIS. — Grantiidae with a syconoid organization. The cortex is composed of tangential triactines and/or tetractines, occasionally with small perpendicular diactines. Longitudinal diactines, if present, are not found exclusively in the cortex, but cross obliquely, at least a part of the choanosome and protrude from the external surface.

DESCRIPTION

Typical species of Grantia have long and regular radial tubes, which may be branched distally, and a relatively thin atrial and cortical skeletons. Diactines frequently protrude from the external surface of the sponge. Many species of Grantia that form small solitary tubes or large bushy sponges have been described from all oceans.
