Ericusa is a small taxonomic genus of medium-sized predatory marine gastropod molluscs in the family Volutidae, the volutes. [1] [2]
Ericusa are endemic to Australia. They are found in temperate waters from southern Queensland to southern Western Australia.
The shells of Ericusa have a small rounded protoconch, are biconical with a rounded shoulder and have an elongate aperture with 4 distinct columellar plicae and a thickened outer lip. The whorls are regular, smooth and convex. The protoconch is globose and deviates 45° from the axis of the shell. The colour pattern of Ericusa is pink or yellow brown overlaid with a varied brown pattern.
The largest species with shells exceeding 200 mm in length are Ericusa fulgetrum and Ericusa sowerbyi.
Ericusa are nocturnal and prey on invertebrates. They have a large foot and siphon and they lay relatively large solitary eggs. [3]
Several infraspecific taxa of Ericusa fulgetra have been named, on the basis of colour patterns of the shell.
Volutidae, common name volutes, are a taxonomic family of predatory sea snails that range in size from 9 mm to over 500 mm. They are marine gastropod mollusks. Most of the species have no operculum.
Haliotis asinina, common name the ass's-ear abalone, is a fairly large species of sea snail, a tropical gastropod mollusk in the family Haliotidae, the abalones, also known as ormers or paua. Both the common name and the scientific name are based on the shape of the shell, which is long, narrow and curved, resembling the shape of a donkey's ear.
Melo miltonis, the southern bailer or southern baler, is a large sea snail, a marine gastropod mollusc in the family Volutidae, the volutes.
Cymbiolacca is a small taxonomic genus of medium-sized predatory marine gastropod mollusc in the family Volutidae, the volutes. This genus is often treated as a subgenus of Cymbiola Swainson, 1831.
Volutoconus is a small taxonomic genus of four rare species of sea snails, medium-sized predatory marine gastropod mollusks in the family Volutidae.
Amoria is a taxonomic genus of medium-sized predatory marine gastropod in the family Volutidae.
Scaphella junonia, common names the junonia, or Juno's volute, is a species of large sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Scaphella is a genus of large sea snails, marine gastropod mollusks in the family Volutidae, the volutes.
Nannamoria is a small taxonomic genus of small-sized sea snails, predatory marine gastropod molluscs in the subfamily Amoriinae of the family Volutidae, the volutes.
Amoria benthalis is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Amoria damonii, common name Damon's volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes. It forms a complex of attractive, large shells which has been studied extensively by Abbottsmith.
Amoria hunteri, common name Hunter's marbled volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Cymbiola aulica, also known as the Princely or Courtier Volute is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Cymbiola nobilis is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes. The snail's shell is commonly collected in the sea shell trade, which has resulted in overharvesting of the snail.
Ericusa fulgetrum, the lightning volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Ericusa sericata, common name : the silk-like volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Ericusa sowerbyi, common name the spindle-shaped volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Livonia mammilla, common name false melon or false baler, is a species of sea snail, a marine gastropod mollusk of the genus Livonia in the family Volutidae, the volutes.
Volutoconus grossi, common name Gross's volute or McMichael's Volute or Tin Can Bay Volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
The subfamily Fulgorariinae contains sea snails, marine gastropod mollusks in the family Volutidae.
