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.
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.

Protoconch of Haliotis asinina when the torsion is complete. There are two different developmental stages which cause torsion. The first stage is caused by the development of the asymmetrical velar/foot muscle which has one end attached to the left side of the shell and the other end has fibres attached to the left side of the foot and head.
