Amalda obesa is a species of sea snail, a marine gastropod mollusk in the family Ancillariidae.[1]
Description
[edit]The length of the shell attains 18.8 mm.
(Original description in Latin) The shell is oval and inflated. It is pale with dark mottling and a central dark band. The spire is short and pyramidal, with the whorls that have defined edges. The aperture is large and features a single tooth, while the small varix is white.
This species is more obese than Amalda oblonga, with a shorter spire. The middle of the body whorl has a broad brown band, above and below which are rows of brown spots; the margination is also variegated. [2]
Distribution
[edit]This marine species occurs off Port Elizabeth, South Africa.
