Craspedida
Craspedida is an order of choanoflagellate, with members with an exclusively organic covering. Craspedid genera ''Salpingoeca rosetta'' S. rosetta has been named for the rosette-shaped colonies formed by its cells. Recent studies show a bacterial sulfonolipid, called rosette inducing factor (RIF-1) produced by ''Algoriphagus machipongonensis ''Algoriphagus'' is a genus in the phylum Bacteroidota (Bacteria). Etymology The name ''Algoriphagus'' derives from:Latin masculine gender noun ''algor'' -''oris'', cold; Greek masculine gender noun , glutton; New Latin masculine gender noun '' ...'' triggers colony formation in S. rosetta.

Monosiga Brevicollis
The choanoflagellates are a group of free-living unicellular and colonial flagellate eukaryotes considered to be the closest living relatives of the animals. Choanoflagellates are collared flagellates, having a funnel shaped collar of interconnected microvilli at the base of a flagellum. Choanoflagellates are capable of both asexual and sexual reproduction. They have a distinctive cell morphology characterized by an ovoid or spherical cell body 3–10 µm in diameter with a single apical flagellum surrounded by a collar of 30–40 microvilli (see figure). Movement of the flagellum creates water currents that can propel free-swimming choanoflagellates through the water column and trap bacteria and detritus against the collar of microvilli, where these foodstuffs are engulfed. This feeding provides a critical link within the global carbon cycle, linking trophic levels. In addition to their critical ecological roles, choanoflagellates are of particular interest to evolutionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salpingoeca Rosetta
''Salpingoeca rosetta'' is a species of Choanoflagellates in the family Salpingoecidae. It is a rare marine eukaryote consisting of a number of cells embedded in a jelly-like matrix. This organism demonstrates a very primitive level of cell differentiation and specialization. This is seen with flagellated cells and their collar structures that move the cell colony through the water. Similar low level cellular differentiation and specification can also be seen in sponges. They also have collar cells (also called choanocytes due to their similarities to choanoflaggellates) and amoeboid cells arranged in a gelatinous matrix. Unlike ''S. rosetta'', sponges also have other cell-types that can perform different functions. Also, the collar cells of sponges beat within canals in the sponge body, whereas Salpingoeca rosetta’s collar cells reside on the inside and it lacks internal canals. Despite these minor differences, there is strong evidence that Proterospongia and Metazoa are highly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
