Teuthology is the study of cephalopods. Cephalopods are members of the class Cephalopoda in the Phylum Mollusca. Some common examples of cephalopods are octopus, squid, and cuttlefish. Teuthology is a large area of study that covers cephalopod life cycles, reproduction, evolution, anatomy and taxonomy.

Beddomeia waterhouseae, also known as Claytons Rivulet freshwater snail, is a species of freshwater snail in the family Tateidae. This species is endemic to northern Tasmania in Australia. The holotype specimen was found in a very small tributary of Little Clayton's Rivulet and is held at the Australian Museum. B. waterhouseae is small and as an adult has a shell measuring between 1.7 to 3.7 mm in length. The shell shape is ovate-conic to broadly conic and has a thin inner lip and no columellar bulge. This species feeds on algae and detritus on rocks. The female of the species lay single eggs in capsules made of sand grains and attached to the underside of rocks or wood. B. waterhouseae is considered vulnerable by the IUCN as it has a very small range and is sensitive to water quality and so may be threatened by disturbances of its habitat. Other threats include habitat loss. Conservation activities such as assessment of the aquatic ecosystem and vegetal surveys are being undertaken in an attempt to preserve this species.
Beddomeia zeehanensis is a species of very small freshwater snail that has a gill and an operculum, an aquatic operculate gastropod mollusk in the family Hydrobiidae. The species was first described in 1993 by Winston Ponder and G.A. Clark.
Osteopeltidae is a taxonomic family of small, deep water sea snails, marine gastropod mollusks in the clade Vetigastropoda. These limpets feed on organic waste on the deep-sea floor; one species, Baleenopelta rotunda, feeds on decaying whale baleen.

Austropyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the Hydrobiidae family. Austropyrgus species are endemic to Australia, where they are found in virtually all freshwater habitats, from high mountain streams to isolated springs in the arid zone.
Austropyrgus centralia is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to northern South Australia. It is only known from a few small seeps and the shallow lower outflow of one larger spring in Dalhousie Springs, Lake Eyre basin.
Austropyrgus foris is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to eastern Victoria, Australia. It is only known from a small stream at Cape Liptrap, near Waratah Bay.
Velesunio wilsonii is a species of freshwater mussel endemic to Australia and comes from the Hyriidae family. Velesunio wilsonii mussels have a thick, dark shell that are sometimes flaky and mostly closed. Velesunio wilsonii have a fleshy foot that sometimes extends outside of the valves. The shell of the Velesunio wilsonii varies from oblong to a symmetrical circle. Velesunio wilsonii size ranges from 40 mm to 120 mm.
Phenacomargarites williamsae is a species of sea snail, a marine gastropod mollusk, in the family Calliostomatidae within the superfamily Trochoidea, the top snails, turban snails and their allies.
Caldicochlea is a genus of freshwater molluscs in the family, Tateidae, endemic to the mound springs of the Great Artesian Basin.
Caldicochlea globosa is a species of freshwater mollusc in the family, Tateidae, endemic to the Dalhousie Springs of the Great Artesian Basin. The species was first described in 1996 as Dalhousia globosa by Winston Ponder, Donald Colgan, T. Terzis, Stephanie Clark and Alison Miller. However, the genus name of Dalhousia had already been used, and thus in 1997, Ponder published the replacement genus name of Caldicochlea.
Buccipagoda is a genus of sea snails, marine gastropod molluscs in the family Buccinidae, the true whelks. It was first described in 1982 under the genus name Kapala by Winston Ponder with the name honouring the FRV Kapala, but the genus name had already been used. Hence, a replacement name was needed and given in 2010. The type species is Buccipagoda kengrahami, formerly Kapala kengrahami.
Xenostrobus is a genus of saltwater, brackish water and freshwater clams, marine bivalve molluscs in the subfamily Xenostrobinae of the family Mytilidae, the mussels.
