Turbo (gastropod)
''Turbo'' is a genus of large sea snails with gills and an operculum, marine gastropod molluscs in the family Turbinidae, the turban snails.Bouchet, P.; Rosenberg, G. (2012). Turbo Linnaeus, 1758. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=151576 on 2012-09-27 ''Turbo'' is the type genus of the family. Description The shells of species in this genus are more or less highly conspiral, thick, about 20–200 mm, first whorls bicarinate, last whorl large often with strong spiral sculpture, knobs or spines, base convex, with or without umbilicus. Species in this genus have a round aperture and a solid, dome-shaped calcareous operculum. This circular operculum commences as a multispiral disc, like that of a '' Trochus'', upon the outer side of which is deposited a thin calcareous layer by a lobe of the foot which projects partly over it. This arrangement produces an operculum which exhibits all the whorls ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbo Petholatus
''Turbo petholatus'' (common name: tapestry turban) is a species of sea snail, marine gastropod mollusk in the family (biology), family Turbinidae. Description The length of the shell varies between 30 mm and 100 mm. The imperforate shell is solid, polished and shining. Its color pattern is rich brown, variously ornamented with dark bands interrupted with white blotches and narrow stripes. The five Whorl (mollusc), whorls are flattened beneath the Suture (anatomy), suture, sometimes carinated above. The Aperture (mollusc), aperture measures about half the length of the shell. It is circular and pearly within. The Peristome (gastropod), peristome and Columella (gastropod), columella are tinged with greenish-yellow. The pattern on the shell is very similar to Turbo moolenbeeki, especially in the brown form Turbo petholathus. The circular Operculum (gastropod), operculum contains four whorls and a nucleus placed one-third the distance across the face. The outer surface ...

Aperture (mollusc)
The aperture is an opening in certain kinds of mollusc shells: it is the main opening of the shell, where the head-foot part of the body of the animal emerges for locomotion, feeding, etc. The term ''aperture'' is used for the main opening in gastropod shells, scaphopod shells, and also for ''Nautilus'' and ammonite shells. The word is not used to describe bivalve shells, where a natural opening between the two shell valves in the closed position is usually called a ''gape (bivalve), gape''. Scaphopod shells are tubular, and thus they have two openings: a main anterior aperture and a smaller posterior aperture. As well as the aperture, some gastropod shells have additional openings in their shells for respiration; this is the case in some Fissurellidae (keyhole limpets) where the central smaller opening at the apex (mollusc), apex of the shell is called an orifice, and in the Haliotidae (abalone) where the row of respiratory openings in the shell are also called orifices.

Turbo Bruneus
''Turbo bruneus'', commonly named the brown (Pacific) dwarf turban or the little burnt turbo, is a species of sea snail, marine gastropod mollusk in the family Turbinidae. These snails are called "turbo" because they can move quite quickly for a snail, using a muscular foot to glide along the ocean floor. They feed on algae and other small organisms that they scrape off rocks and other surfaces. Turbo bruneus snails are important members of their ecosystem because they help to control the population of algae and other small organisms, which can become overgrown and harm other marine life if left unchecked. Description The length of the shell varies between 20 mm and 50 mm. The size of the Turbo bruneus shells are basically about 5-6 centimeters in diameter and have a rounded, conical shape with a pointed vertex. The color of the shell is brown, with a glossy, polished appearance. These snails are found in a wide range of habitats, including coral reefs, rocky shore ...

ITIS
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. it contains over 839,000 scientific names, synonyms, an ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic gr ...

Radula
The radula (; : radulae or radulas) is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the mollusks, and is found in every class of mollusk except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth. Within the gastropods, the radula is used in feeding by both herbivorous and carnivorous snails and slugs. The arrangement of teeth ( denticles) on the radular ribbon varies considerably from one group to another. In most of the more ancient lineages of gastropods, the radula is used to graze, by scraping diatoms and other microscopic algae off rock surfaces and other substrates. Predatory marine snails such as the Naticidae use the radula plus an acidic secretion to bore through the shell of other mollusks. Other predatory marine snails, ...
