common name for members of the aquatic animal phylum Porifera, and for the dried, processed skeletons of certain species used to hold water.
s have several cell types:
* Choanocytes (also known as "collar cells"), flagellated cells which function as the '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.
Blue Adocia species
The exact identity of this beautiful, bright blue has not yet been ascertained. It is soft and spongy in texture and grows in irregular branches with a row of large, round osculae running along each branch.
Sponges are an important part of the ecosystem; they're a source of food for nudibranchs, chitons, sea stars, turtles and some fishes.

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.
s 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 s 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.
Spawning pairs are strongly territorial, with usually both members vigorously defend their areas against neighboring pairs.

Juveniles and adults show a wide variety of prey, mostly such as conchs, clams, crabs, horseshoe crabs, shrimps, sea urchins, s, fishes, squids, and octopuses.
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 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 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.
Habits: Adults feed on fish, gastropods, echinoderms (sea urchins), and in particular, s. A throat lined with spines aids in digestion of s.
An alternative to fruit is to cut a piece of new sponge to fit inside a small animal feeding bowl or custard-size cup.
Use a filter or internal box filter that does not use chemical filtration or Carbon, for these products will remove many types of medications.
Diet: Hawksbills are omnivorous, consuming sea grasses, sea urchins, barnacles, small animals and their favorite food, sponges.
Members of the phylum Porifera, ("pore-bearer") are commonly known as s, and approximately 5,000 have been described by scientists. Until the 18 th century, scientists mistook them for plants.
The dolphins break sponges off and cover their snouts with them thus protecting their snouts while foraging.
The males now become greatly emaciated, and cease to gobble, their breast- 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 s.
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.
They feed mainly on s by using their narrow pointed beaks to extract them from crevices on the reef, but also eat sea anemones and jellyfish.
Chimps sometimes chew leaves to make them absorbent and then use them as a sponge, dipping them in water and sucking out the moisture.

They create tools from natural objects and have been observed using rocks to smash nutshells, sticks as weapons, and even leaves as sponges. This fascinating behavior, however, is not instinctual, but is culturally acquired through observation.
