Haliotis cracherodii, the black abalone, is a species of large edible sea snail, a marine gastropod mollusk in the family Haliotidae, the abalone. [3]This species is relatively small compared with most of the other abalone species from the eastern Pacific, and it has a relatively smooth dark shell.
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 (known as tremata), characteristic of the genus. These holes are respiratory apertures for venting water ...

Pleurotomariacea is one of two names that are used for a taxonomic superfamily of sea snails that are an ancient lineage and are well represented in the fossil record.The name Pleurotomariacea is used by paleontologists, who, because they usually have only the hard parts of mollusks to study, often use a slightly different scheme of classification from that used by scientists who study living ...
Due to Black Abalone (Haliotis Cracherodii) being native species to the Channel Islands being overly harvested, their populations are now low making them an endangered species by the National Oceanic and Atmospheric Administration (NOAA) Fisheries since October 2011. [53]
