The Clathrinida are an order of sponges in the class of calcareous sponges . It is a species-rich order with variable growth forms and all stages of development, from olynthus-like sponges with simple, non-branching tubes to complex species with complex inflow and outflow systems. Type family is Clathrinidae Minchin , 1900.

features

Clathrinida are calcified sponges with exclusively free (not hypercalcified) needles ( sclerite , spicula), without hypercalcified outer layer, calcified scales or plates.

Systematics

Clathrinida is considered to be a monophyletic , homogeneous group. Borojevic et al. (1990) therefore proposed a single order Clathrinida which includes all calcinea without a hypercalcified skeleton, as opposed to a division into two orders, Clathrinida and Leucettida, as suggested by Hartman (1958).

6 families with 16 genera have been described of Clathrinida:

The World Register of Marine Species also mentions Clathrinida incertae sedis Borojevic, Boury-Esnault, Manuel & Vacelet , 2002.
