Euplectella is a genus of glass sponges which includes the well-known Venus' Flower Basket. Glass sponges have a skeleton [ 2 ] made up of silica spicules that can form geometric patterns. These animals are most commonly found on muddy sea bottoms in the Western Pacific and Indian Oceans. [ 3 ]
Venus' flower basket (Euplectella aspergillum) is a species of marine glass sponge found in the deep waters of the Pacific Ocean, usually at depths below 500 m (1,600 ft). Like other sponges, they feed by filtering sea water to capture plankton and marine snow . [ 1 ]
Bolosoma stalked glass sponge. Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed siliceous spicules, often referred to as glass sponges.They are usually classified along with other sponges in the phylum Porifera, but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma.
Euplectellidae is a family of glass sponges (Hexactinellids) belonging to the order Lyssacinosa, first represented in the Ordovician fossil record, substantially older than molecular estimates of the clade's age. [1]
The generic name, Euplectella, is derived from the Latin plecto, meaning "to weave", and the prefix eu-, in reference to the "complexity of the interweaving of its component threads". [2] The specific epithet, gibbsa, is derived from the Charlie-Gibbs fracture zone, the species' type locality. [3]
Among extant sponges, only the calcareous sponges can produce calcite spicules, whereas other classes' spicules are siliceous. Some lineages among demosponges and a few calcareans have massive calcium carbonate basal skeletons, the so-called coralline sponges or sclerosponges.
In 1901, sponge divers found a strange device off the coast of the Greek island of Antikythera in the Aegean Sea. The device is a wooden box with a complex system of gears and a hand crank.
The generic name, Euplectella, is derived from the Latin plecto, meaning "to weave", and the prefix eu-, in reference to the "complexity of the interweaving of its component threads". [2] The specific epithet, sanctipauli, is derived from the São Paulo Ridge in the southwest Atlantic Ocean, the type locality of the species. [3]
