A spongivore is an animal anatomically and physiologically adapted to eating animals of the phylum Porifera, commonly called sea sponges, for the main component of its diet. As a result of their diet, spongivore animals like the hawksbill turtle have developed sharp, narrow bird-like beak that allows them to reach within crevices on the reef to ...
All freshwater and most shallow-water marine sponges have leuconid bodies. The networks of water passages in glass sponges are similar to the leuconid structure. [18] In all three types of structure, the cross-section area of the choanocyte-lined regions is much greater than that of the intake and outlet channels.
The cells in the sponge walls filter food from the water. Whatever is not uptaken by the sponge is pumped through the body out of a large opening. The class demosponges are the most abundant and diverse of the sponge classes. Some of the sponges in this class have skeletons made from silicon-containing spicules, spongin fibers, or both ...
Callyspongia (Cladochalina) aculeata, commonly known as the branching vase sponge is a species of sea sponge in the family Callyspongiidae. [1] Poriferans are typically characterized by ostia, pores that filter out plankton, with an osculum as the opening which water leaves through, and choanocytes trap food particles.
Cliona celata, occasionally called the boring sponge, is a species of demosponge belonging the family Clionaidae. [1] It is found worldwide. This sponge bores round holes up to 5 millimetres (0.20 in) in diameter in limestone or the shells of molluscs, especially oysters.
About 311 million years ago, in the Late Carboniferous, the order Spongillida split from the marine sponges, and is the only sponges to live in freshwater environments. [8] Some species are brightly colored, with great variety in body shape; the largest species are over 1 m (3.3 ft) across. [ 6 ]
Chondrocladia lyra, also known as the lyre sponge or harp sponge, is a species of carnivorous deep-sea sponge first discovered off the Californian coast living at depths of 10,800–11,500 feet (3,300–3,500 m) by Welton L. Lee, Henry M Reiswig, William C. Austin, and Lonny Lundsten from the Monterey Bay Aquarium Research Institute (MBARI).
Cladorhizidae sponges are typically found on oceanic ridges and seamount systems, where they attach to the seafloor and extend their feeding structures into the water column to capture passing prey. Due to their deep-sea habitat, little is known about the ecology and behavior of these sponges.
