Amphilectus Strepsichelifer
''Amphilectus strepsichelifer'' is a species of demosponges found in the Atlantic waters around Cape Verde, western Africa. The species name is a combination of the Latin ''strepsis'' = twisted, and ''chelifer'' = bearing chelae, reflecting the twisted condition of the chelae. The species was discovered in 1986 in the waters of Canal de São Vicente The Canal de São Vicente is a strait of the Atlantic Ocean separating the islands of Santo Antão and São Vicente, Cape Verde. At its narrowest point, it is wide. The ferry route between the ports of Porto Novo on Santo Antão and Mindelo on ..., west of São Vicente, at about 350 m depth, on hard bottom.

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 ...

Chelae
A chela ()also called a claw, nipper, or pinceris a pincer-like organ at the end of certain limbs of some arthropods. The name comes from Ancient Greek , through New Latin '. The plural form is chelae. Legs bearing a chela are called chelipeds. Another name is ''claw'' because most chelae are curved and have a sharp point like a claw. Chelae can be present at the tips of arthropod legs as well as their pedipalps. Chelae are distinct from spider chelicerae in that they do not contain venomous glands and cannot distribute venom. See also * Pincer (biology) * Pincer (tool) Pincers are a hand tool used in many situations where a mechanical advantage is required to pinch, cut or pull an object. Pincers are first-class levers, but differ from pliers in that the concentration of force is either to a point, or to an ... References Arthropod anatomy {{Arthropod-anatomy-stub ...

Canal De São Vicente
The Canal de São Vicente is a strait of the Atlantic Ocean separating the islands of Santo Antão and São Vicente, Cape Verde. At its narrowest point, it is wide.

Poecilosclerida
Poecilosclerida is an order of the demosponge class. It is the most speciose demosponge order with over 2200 species (World Porifera Database). It contains about 25 recognised families. They are characterised by having chelae microscleres, that is, the minute spicules scattered through the tissues, usually in the 10-60 μm range, have a shovel-like structure on the end. Most of the families are viviparous with parenchymella larvae that are uniformly ciliated The cilium, plural cilia (), is a membrane-bound organelle found on most types of eukaryotic cell, and certain microorganisms known as ciliates. Cilia are absent in bacteria and archaea. The cilium has the shape of a slender threadlike projecti .... Families As of 2018, the following families are recognized: References {{demosponge-stub ...

Fauna Of Cape Verde
The wildlife of Cape Verde is spread over its archipelago of ten islands and three islets, which all have parks under their jurisdiction by decree promulgated by the Cape Verde government. Located off the west coast of Africa, the total land area of the island nation is . The wildlife consists of many tropical dry forest and shrub land, endemic flora and fauna, and rare breeding seabirds and plants, which are unique to this group of islands. Some of the wildlife species of Cape Verde are considered as endemic, evolving over millions of years of isolation; the grey-headed kingfisher (''Halcyon leucocephala'') survived here on insects in the absence of water in the lands of the islands. In the process of development, many lands in the islands were converted to agricultural fields and several hundred varieties of herbaceous plant and tree species were introduced, resulting in depletion of the original vegetation. However, efforts are now underway at reforestation to improve the wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
