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 abalone, also known as ormers or pāua. 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.
The last whorl, known as the body whorl, is auriform, meaning that the shell resembles an ear, giving rise to the common name "ear shell". Haliotis asinina has a somewhat different shape, as it is more elongated and distended.
Haliotis asinina has a somewhat different shape, as it is more elongated and distended. The shell of Haliotis cracherodii cracherodii is also unusual as it has an ovate form, is imperforate, shows an exserted spire, and has prickly ribs. A mantle cleft in the shell impresses a groove in the shell, in which are the row of holes characteristic of ...
This list of abalone synonyms is a list of scientific names that have been given to abalone species worldwide. Carl Linnaeus described the type species Haliotis asinina in 1758, [1] and over the centuries a large number of additional species of abalone were named using the proper scientific process for naming a species.
Various gastropods from different types: black slug (a slug), Haliotis asinina (an abalone), Cornu aspersum (a land snail), Notarchus indicus (a seahare), Patella vulgata (a limpet), and Polycera aurantiomarginata (a nudibranch).

Protoconch of Haliotis asinina when the torsion is complete. A protoconch (meaning first or earliest or original shell) is an embryonic or larval shell which occurs in some classes of molluscs, e.g., the initial chamber of an ammonite or the larval shell of a gastropod. In older texts it is also called "nucleus".
Pāua are gathered recreationally and commercially, with strict catch limits are set for both. For recreational fishermen this is five pāua per person per day. The minimum legal size for caught pāua is 125 mm (5") for Haliotis iris and 80 mm (3 + 1 ⁄ 4") for Haliotis australis, measured in a straight line at the greatest length of the shell ...
