Acarnidae
Acarnidae is a family of sponges belonging to the order Poecilosclerida. It has a global distribution, although several genera occur primarily in colder temperate waters, and several have very restricted ranges. It is estimated that there are several hundred species. Description Species form encrusting, massive, fan-shaped or digitate (small, un-splitting branches growing from a spreading base) growth forms that may burrow into the substrate. The species of many genera produce fistules. The outer skeleton is made of tylotes (long, slender megascleres with knobs at both ends) which may be modified to have a spined base as well as strongyles (megascleres with both ends blunt or rounded). These form tangential and/or paratangential tracts, often with an irregular or halichondroid arrangement. The inner skeleton is made of styles (megascleres with end pointed and the other end rounded) or modified styles. These form massive networks to create isodictyal (triangular meshes in whic ...
