Raphitomidae
Raphitomidae is a family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". ''Malacologia'' 47(1-2). . 397 pp. Bouchet, Kantor ''et al''. elevated in 2011 the subfamily Raphitominae (which at that point had been placed in the family Conidae) to the rank of family. This was based on a cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. The family was found to be monophyletic. Description The Raphitomidae is the largest, most diverse and most variable taxon in the Conoidea, with the greatest number of species and the largest ecological range (from the tropics to the pole) and largest vertical range (intertidal to hadal depths). The shells of species in the Raphitomidae are very variable in shape (buccinoid to ovate, elongate-fusiform, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Snail
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example species in the genus '' Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large group of animals and a very diverse one. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide when they can move around in the air. These air-breathing species includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kermia
''Kermia'' is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae. This genus is closely related to ''Pseudodaphnella'' Boettger, 1895. They form together a genus-complex with a highly underestimated diversity, leading to intermixed clades. The lack of morphologic criteria requires the generic assignment of several species clearly to be reconsidered. Description The elongate, fusiform shell has a narrow aperture that is nearly half the length of the shell. The protoconch consists of two whorls. But only in a few species the sculpture of the protoconch is coarsely diagonally reticulate. The shell structure is reticulate with glossy nodules on the intersections of the ribs and lirae. The siphonal canal is short and wide. The U-shaped or linguiform anal sinus is deep, located near the suture and is surrounded by a thick outer lip. The outer lip is denticulate within. The columella is smooth. Distribution This marine genus is widely distributed in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
