Sponges have several cell types:
* Choanocytes (also known as "collar cells"), flagellated cells which function as the sponge's digestive system, are remarkably similar to the protistan choanoflagellates.

Sponges are filter feeders. They draw water in through the pores located throughout their body wall into a central cavity. The central cavity is lined with collar cells which have a ring of tentacles that surround a flagellum.

Sponges are found in virtually all aquatic habitats, although they are most common and diverse in the marine environment. Many species contain toxic substances, probably to discourage predators.

Sponges are the principal diet of hawksbills once they enter shallow coastal waters and begin feeding on the bottom. While diet studies have focused on the Caribbean, there is evidence that eating sponges is a worldwide feeding habit.

The sponges (Porifera) were long thought to have diverged from other animals early. They lack the complex organization found in most other phyla. Their cells are differentiated, but in most cases not organized into distinct tissues.

Hawksbills nest on beaches in tropical oceans of the world, often sharing beaches with green turtles. Nests are typically placed under vegetation.

Feeds on sponges, algae, bryozoans, zoantharians, gorgonians, and tunicates.
Life History
Spawning pairs are strongly territorial, with usually both members vigorously defend their areas against neighboring pairs.

Leaves are chewed and then wadded to make a sponge to soak up water from rain-filled plants. They form gloves from leaves when climbing prickly surfaces.

We find simple aquarium sponge filters to be the most cost efficient. They also do not cause much turbulence, which is good when dealing with angelfish. One or two large sponge filters will handle most aquariums.

The walls also had a number of moray eels, small triplefins, sponges, tunicates, anemones, and the wonderful Lord Howe Coralfish, a tropical species in the butterflyfish family that reaches the edge of its range in the Poor Knights.

The males now become greatly emaciated, and cease to gobble, their breast-sponge becoming flat. They then separate from the hens, and one might suppose that they had entirely deserted their neighbourhood.

Encrusting sponges are obvious on the exterior, as are the effects of two boring sponges. Smaller borings are the result of Cliona, whereas Siphonodictyon produces larger holes. Halimeda flakes and worm tubes are also present.

The hawksbill lives the early part of its life in the open ocean but then is more often found around coral reefs and shallow lagoons, where it feeds mostly on sea sponges.

They are carnivores that slowly ply their range grazing on algae, sponges, anemones, corals, barnacles, and even other nudibranchs. To identify prey, they have two highly sensitive tentacles, called rhinophores, located on top of their heads.
