Gadilinidae is a family of relatively large tusk shells, scaphopod mollusks in the order Dentaliida. [1]
Richard Kenneth Dell was a New Zealand malacologist.
The tusk shells or tooth shells, technically the Scaphopoda, are members of a class of shelled marine mollusc with worldwide distribution, and are the only class of exclusively infaunal marine molluscs. Shells of species within this class range in length 0.5–18 cm (0.20–7.09 in). Members of the order Dentaliida tend to be larger than those of the order Gadilida.
The Rostroconchia is a class of extinct molluscs dating from the early Cambrian to the Late Permian. They were initially thought to be bivalves, but were later given their own class. They have a single shell in their larval stage, and the adult typically has a single, pseudo-bivalved shell enclosing the mantle and muscular foot. The anterior part of the shell probably pointed downward and had a gap from which the foot could probably emerge. Rostroconchs probably lived a sedentary semi-infaunal lifestyle. There were probably more than 1,000 species of members of this class.
Dentaliida is one of the two orders of scaphopod mollusks, commonly known as elephant's tusk shells. The order Dentaliida contains most of the larger scaphopods, and is distinguished from the other order by the shape of its shell, the shape of the foot, and the arrangement of some of their internal organs.
Gadilida is an order of very small tusk shells, marine scaphopod molluscs.
Siphonodentalium colubridens is a tusk shell or scaphopod in the family Gadilidae of the order Dentaliida.
Antalis diarrhox is a species of tusk shell, a marine scaphopod mollusk in the family Dentaliidae.
Dentalium is a large genus of tooth shells or tusk shells, marine scaphopod molluscs in the family Dentaliidae. The genus contains 50 described species and about 50 extinct species.
Gadila is a genus of small tusk shells, which are marine scaphopod molluscs in the family Gadilidae.
Entalinidae is a family of tusk shells, marine scaphopod mollusks in the order Gadilida.
Costentalina is a genus of medium-sized tusk shells, marine scaphopod molluscs in the family Entalinidae.
Costentalina elegans is a species of medium-sized tusk shell, a marine scaphopod mollusc in the family Entalinidae. It is found in Australia and the Indian Ocean. It is an abyssal species and lives at a depth of 5100 to 5800 m.
Polyschides is a genus of gadilid tusk shell (scaphopod).
The Rhabdidae are scaphopod members of the same molluscan family, belonging to the order Dentaliida. It includes only one genus, Rhabdus, and five species, as follows:
Fustiaria is a genus of scaphopods in the order Dentaliida and is the only genus comprising the family Fustiariidae, with 24 species.
Dentalium elephantinum, the elephant tusk, is a species of scaphopod mollusc. Its shell is often deep green fading to white at its tip and has between eight and 17 strong ribs along its sides. Adults are about 70 mm in length with an diameter of about 11 mm at the shell aperture. It is native to Amboyna, the Philippine Islands, and the Red Sea.
Compressidentalium is a genus of tusk shells, marine scaphopod mollusks.
Laevidentaliidae is a family of relatively large tusk shells, scaphopod mollusks in the order Dentaliida.
Pulsellidae is a family of molluscs belonging to the suborder Gadilimorpha in the order Gadilida.
Pictodentalium is a genus of molluscs belonging to the family Dentaliidae.
