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 ]
The calcareous sponges [2] [3] (class Calcarea) are members of the animal phylum Porifera, the cellular sponges.They are characterized by spicules made of calcium carbonate, in the form of high-magnesium calcite or aragonite.
From citrus to figs to fish, find out which foods you should be adding to your diet to get more calcium.
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 ]
Calcium carbonate biomineralization, the most widespread type among animal phyla, [37] evolved several times independently, resulting in multiple recruitments of the same genes for biomineralization in different lineages. [38] Among these genes, members of the alpha carbonic anhydrase gene family (CAs) are essential for biomineralization. [39]
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]
For example, for calcium the U.S. Food and Drug Administration set the recommended intake for adults over 70 years at 1,200 mg/day and the UL at 2,000 mg/day. [19] The European Union also sets recommended amounts and upper limits, which are not always in accord with the U.S. [ 20 ] Likewise, Japan, which sets the UL for iodine at 3000 μg ...
Calcium compounds are widely used in many industries: in foods and pharmaceuticals for calcium supplementation, in the paper industry as bleaches, as components in cement and electrical insulators, and in the manufacture of soaps. On the other hand, the metal in pure form has few applications due to its high reactivity; still, in small ...
