Athoracophorus is a genus of air-breathing, land slugs, terrestrial pulmonate gastropod molluscs in the family Athoracophoridae.
Species in the genus Athoracophorus include:
The body of the animal is limaciform, subcylindrical and tapering behind; inferior tentacles wanting. Mantle is anterior, small, triangular, lateral, adherent, enclosing the shell-plate. There are no longitudinal furrows above the margin of the foot, and no caudal mucous pit. There is no distinct locomotive disk. External respiratory and anal orifices are on the right central margin of the mantle. Orifice of the combined genital system is behind and below the right eye-peduncle. [1]
The shell-plate is internal, flat, calcareous, oblong and sometimes in separate grains. [1]
Jaw is smooth, with median projection and quadrate accessory plate. [1]
Lingual membrane is with peculiarly shaped teeth, with long, narrow, curving, base of attachment, and low, transverse, multifid cusp. [1]
The animal has peculiar dorsal grooves. [1]
Aplysiidae is the only family in the superfamily Aplysioidea, within the clade Anaspidea. These animals are commonly called sea hares because, unlike most sea slugs, they are often quite large, and when they are underwater, their rounded body shape and the long rhinophores on their heads mean that their overall shape resembles that of a sitting rabbit or hare. Sea hares are however sea snails with shells reduced to a small plate hidden between the parapodia, and some species are extremely large. The Californian black sea hare, Aplysia vaccaria is arguably the largest living gastropod species, and is certainly the largest living heterobranch gastropod.
A siphon is an anatomical structure which is part of the body of aquatic molluscs in three classes: Gastropoda, Bivalvia and Cephalopoda.
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.
Limax maximus, known by the common names great grey slug and leopard slug, is a species of slug in the family Limacidae, the keeled slugs. It is among the largest keeled slugs, Limax cinereoniger being the largest.
Schizoglossa novoseelandica is a predatory species of air-breathing land slug or semi-slug, a terrestrial gastropod mollusc in the family Rhytididae. It is the type species of the genus Schizoglossa and is found only in New Zealand. The survival of this species is not threatened; it is not listed in the 2009 IUCN Red List nor is it in the 2005 New Zealand Threat Classification System lists.
The pneumostome or breathing pore is a respiratory opening of the external body anatomy of an air-breathing land slug or land snail. It is a part of the respiratory system of gastropods.
Athoracophoridae, common name the leaf-veined slugs, are a family of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the infraorder Stylommatophora, the stalk-eyed snails and slugs. Many of the species have an attractive pattern on their dorsal surface which resembles the veins in a leaf, hence the common name.
Geomalacus is a genus of large air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the family Arionidae, the roundback slugs.
Fiona pinnata, common name Fiona, is a species of small pelagic nudibranch, a marine gastropod mollusk in the superfamily Fionoidea. This nudibranch species lives worldwide on floating objects on seas, and feeds mainly on barnacles, specifically goose barnacles in the genus Lepas.
Philomycidae are a family of air-breathing land slugs. They are terrestrial pulmonate gastropod mollusks in the superfamily Arionoidea.
Anostoma, common name the up-mouth snails, is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Odontostomidae. Snails in this genus are found in Brazil.
Hyalimax is a genus of small, air-breathing, land slugs, terrestrial pulmonate gastropod molluscs in the family Succineidae, the amber snails. This genus has no external shell, but it has an almost flat internal shell plate.
Juliidae, common name the bivalved gastropods, is a family of minute sea snails, marine gastropod mollusks or micromollusks in the superfamily Oxynooidea, an opisthobranch group.
The respiratory system of gastropods varies greatly in form. These variations were once used as a basis for dividing the group into subclasses. The majority of marine gastropods breathe through a single gill, supplied with oxygen by a current of water through the mantle cavity. This current is U-shaped, so that it also flushes waste products away from the anus, which is located above the animal's head, and would otherwise cause a problem with fouling.
Mariaella is a genus of air-breathing land slugs, a terrestrial pulmonate gastropod mollusks in the family Ariophantidae.
Mariaella dussumieri is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Ariophantidae.
Spergo glandiniformis is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.
Tellimya ferruginosa is a species of small marine bivalve mollusc in the family Lasaeidae. It is found on the eastern side of the Atlantic Ocean.
Lutraria lutraria is a species of large marine bivalve mollusc in the family Mactridae. Its common names include the otter shell and the common otter shell. It occurs in coastal regions of the north east Atlantic Ocean where it lives buried in the sand.
Eulima glabra is a species of small parasitic sea snail, a marine gastropod mollusk in the family Eulimidae. The species is one of a number within the genus Eulima.
