Amoria undulata, common name wavy volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes. [1]
This marine species occurs off East Australia and Tasmania. [2]
The length of the shell varies between 60 mm and 120 mm. [2] These shells are elongated, fusiform, smooth and solid and roundly shouldered, with long pointed conical spire. Suture shows a callous edge. The aperture is elongate, salmon to orange in colour, with smooth outer lip, thickened in adults. The base colour of the external surface of the shell is fawn or white-cream, with thin axial wavy brown lines. Foot shows similar coloured zigzag lines and stripes. [3] [4] [5]
These sea snails live intertidally on sand and mud, at depths of 9 to 503 m. They live in deeper waters in their northern range. They emerge only at night to feed. [4] [5] [6]
These gastropods are carnivore, mainly feeding on other sea snails. In the spring Amoria undulata migrates from deep water to shallow water sandbanks to breed. It lays egg masses similar to a hollow cylinder, with a diameter of 16–20 millimetres (0.63–0.79 in). The embryos hatch as well developed juveniles and crawl away. [4] [5]
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.
Amoria is a taxonomic genus of medium-sized predatory marine gastropod in the family Volutidae.
Scaphella is a genus of large sea snails, marine gastropod mollusks in the family Volutidae, the volutes.
Voluta is a genus of medium to large sea snails, marine gastropod molluscs in the family Volutidae, the volutes.
Voluta musica, common name the music volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Voluta ebraea, common name the Hebrew volute, is a species of medium-sized sea snail, a marine gastropod mollusk in the family Volutidae, the volutes. The Hebrew volute is endemic to Brazil, where it is collected both for food and for its shell, which is highly desired for ornamental purposes. Recent studies indicate that natural populations of Voluta ebraea may be suffering declines due to overfishing and overexploitation.
