Tetilla (sponge)
''Tetilla'' is a genus of demosponges in the family Tetillidae. It is widely distributed. They are mainly found in deeper habitats. Description These globular sponges lack porocalices (special pore bearing pits) and auxiliary megascleres. The surface is covered with conical elevations (conules) or uniformly covered in minute spines. They have few oscules. These are typically located at the top. Spicule strands at the base act as a root system, attaching the sponge to the substrate. There is no visible cortex when a cross-section is taken. The spirally radiate skeleton is made of bundles of oxeas (needle-shaped spicules Spicules are any of various small needle-like anatomical structures occurring in organisms Spicule may also refer to: *Spicule (sponge), small skeletal elements of sea sponges *Spicule (nematode), reproductive structures found in male nematodes ( ...) originating from the center of the sponge. These become mixed with triaenes (elongated spicules with three rays ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demosponge
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order ( Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are ove ...
