About Amoria undulata (Lamarck, 1804)
The shell of Amoria undulata has an elongated, fusiform shape, and grows to between 60 and 120 millimeters in length. The species has a characteristic smooth, solid shell with a rounded shoulder profile, ending in a long, pointed, conical spire. The edge of the shell's suture is calloused. The aperture is elongated, and ranges in color from salmon to orange. In adult individuals, the outer lip is smooth and thickened. The base color of the outer shell surface is fawn or white-cream, marked with thin, axial, wavy brown lines. The foot of the snail shares similar base coloration, and has zigzag lines and stripes. This marine species is endemic to Australia, and is found off the coasts of New South Wales, Queensland, South Australia, Tasmania, Victoria, and Western Australia. These sea snails live intertidally on sand and mud, at depths from 9 to 503 meters. In their northern range, they inhabit deeper waters, and they only emerge to feed at night.
