Carinaria
''Carinaria'' is a genus of medium-sized floating sea snails, pelagic gastropod molluscs in the family Carinariidae. Anatomy The cylindrical and elongate body consists of three parts : a short proboscis, a well-developed trunk and tail region of variable size. The size of this tail goes from very small in ''Carinaria galea'' to very large in ''Carinaria cristata''. The well-developed swimming fin is located in both sexes at the back of the trunk and has at its back margin a small fin sucker. The right tentacle is small or vestigial. The cuticle is thick and gelatinous. The shells are known as “Venus slippers.” Species The World Register of Marine Species includes the following species within the genus ''Carinaria'': * ''Carinaria cithara'' Benson, 1835 – harp carinaria * '' Carinaria cristata'' (Linnaeus, 1767) – Indo-Pacific * ''Carinaria galea'' Benson, 1835 – helmet carinaria; Indo-Pacific * '' Carinaria japonica'' Okutani, 1955 – Japan, North Pacific * ''Carin ...

Carinaria Cristata
''Carinaria cristata'', commonly known as the glassy nautilus, is a species of pelagic marine gastropod mollusc in the family Carinariidae. It is found in the Pacific Ocean and is described as being holoplanktonic, because it spends its entire life as part of the plankton. It was first described by Carl Linnaeus in 1767. Its fragile shell was much prized by early conchologists for their collections, being so rare that it was said to be worth more than its weight in gold. Description ''Carinaria cristata'' is a very large gastropod mollusc that can reach a length of . The shell is a ribbed, cap-shaped cone, about as wide as it is long. It is relatively small, and the body is too large to retract inside it. The body consists of a short proboscis, a central portion and a crested tail. The whole is roughly cylindrical and has a swimming fin on the opposite side from the shell, with a small sucker on its edge. The gelatinous body is translucent, and the gut and its contents can be s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carinaria Galea
''Carinaria galea'', common name the helmeted carinaria, is a species of sea snail, a marine pelagic marine gastropod mollusc in the family Carinariidae. It was first described in 1835 by William Henry Benson, an amateur malacologist in the Bengal Civil Service. Description Benson described the shell of ''Carinaria galea'' in detail as "Shell dextral, with the last whorl incurved, compressed, conical, nearly embracing the terminal spire, marked with transverse rugae, broadly keeled. Keel with very oblique rugae, which are curved upwards in the direction of the spire. Aperture transverse, ovate, narrowed towards the keel." It is a large snail reaching a total body length of . The shell is conical, taller than it is wide, and has a well-developed keel. The body is slender and cylindrical and cannot be retracted into the shell. It has a thin skin with a few large tubercles. The body is transparent and the mouthparts, gut and dark retinas can easily be seen. A pigmented area contai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carinariidae
Carinariidae, known by the common name "heteropods" like their relatives in the Pterotracheoidea, is a taxonomic family of swimming or floating sea snails, pelagic marine gastropod molluscs in the clade Littorinimorpha. Distribution The snails of this family occur worldwide in the pelagic zone of tropical to subtropical seas. floating or swimming by moving up and down the fin-shaped front part of their foot. Feeding habits They feed on jellyfish, larvae of other snails and on zooplankton. Anatomy The cylindrical body of these snails can be divided in three regions: the proboscis, the trunk and the tail region. The body is elongated and much longer than the reduced shell. But in ''Pterosoma'' the trunk is wider and is somewhat disc-shaped. The taenioglossan radula has seven teeth in each row: one central tooth, flanked on each side by one lateral and two marginal teeth. The central tooth has three central cusps and on each side a large process backing away from the center. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine. Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French National Assembly founded the Muséum ...

Tentacle
In zoology, a tentacle is a flexible, mobile, and elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work mainly like muscular hydrostats. Most forms of tentacles are used for grasping and feeding. Many are sensory organs, variously receptive to touch, vision, or to the smell or taste of particular foods or threats. Examples of such tentacles are the eyestalks of various kinds of snails. Some kinds of tentacles have both sensory and manipulatory functions. A tentacle is similar to a cirrus, but a cirrus is an organ that usually lacks the tentacle's strength, size, flexibility, or sensitivity. A nautilus has cirri, but a squid has tentacles. Invertebrates Molluscs Many molluscs have tentacles of one form or another. The most familiar are those of the pulmonate land snails, which usually have two sets of tentacles on the head: when extended ...

Arthur William Baden Powell
Arthur William Baden Powell (4 April 1901 – 1 July 1987) was a New Zealand malacologist, naturalist and palaeontologist, a major influence in the study and classification of New Zealand molluscs through much of the 20th century. He was known to his friends and family by his third name, "Baden". Biography Early life The name Baden had been a given name in a Powell family since 1731, when Susannah Powell née Thistlethwayte (1696–1762) gave to her child (1731–1792) the maiden name of her mother, Susannah Baden (1663–1692). The name Baden, particularly when associated with the surname Powell, became famous in 1900–1901, the year Arthur William Baden Powell was born, because of the siege of Mafeking, the most famous British action in the Second Boer War, which turned the British commander of the besieged, Robert Baden-Powell, into a national hero. Throughout the British Empire, babies were named after him. No family connection has yet been established between Arthur W ...
