Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include greater than 90% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). [5] They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite [citation ...
All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. All three sponge body plans (asconoid, syconoid, and leuconoid) can be found within the class Calcarea. Typically, calcareous sponges are small ...
They are found in all oceans of the world, although they are particularly common in Antarctic and Northern Pacific waters. [ 3 ] They are more-or-less cup-shaped animals, ranging from 10 to 30 centimetres (3.9 to 11.8 in) in height, with sturdy skeletons made of glass -like silica spicules , fused to form a lattice.
Venus' flower baskets are found in the western Pacific Ocean nearby the Philippine Islands. Other species of this genus occur throughout oceans around the world, including near Japan and in the Indian Ocean. [4] This sponge's habitat is on the rocky areas of the benthic seafloor, where it lives and grows connected to hard substrate for its ...

Researchers in Russia on Monday unveiled the remarkably well-preserved remains of a 50,000-year-old female baby mammoth found in thawing permafrost in the Yakutia region of Siberia.
Spongilla was first publicly recognized in 1696 by Leonard Plukenet and can be found in lakes, ponds and slow streams. [2] Spongilla have a leuconoid body form with a skeleton composed of siliceous spicules. They are sessile organisms, attaching themselves to hard substrate like rocks, logs and sometimes to ground.
