The number of species recognized worldwide ranges between 30 [3] and , [4] with over species-level taxa described. The most comprehensive treatment of the family considers 56 species valid, with 18 additional subspecies.

The shells of abalones have a low, open, spiral structure, and are characterized by having several open respiratory pores in a row near the shell's outer edge.

The thick inner layer of the shell is composed of nacre , which in many species of abalone is highly iridescent, giving rise to a range of strong, changeable colors, which make the shells attractive to humans as decorative objects, in jewelry, and as a source of colorful mother-of-pearl.

The shell of abalones is convex , rounded to oval shape, and may be highly arched or very flattened. The shell of the majority of species is ear-shaped, presenting a small, flat spire and two to three whorls.

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. 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 from the gills and for releasing sperm and eggs into the water column.

They make up what is known as the selenizone which forms as the shell grows. This series of eight to 38 holes is near the anterior margin. Only a small number are generally open.

The older holes are gradually sealed up as the shell grows and new holes form. Therefore, the number of tremata is not characteristic for the species.

Each species has a number of open holes, between four and 10, in the selenizone. This number is not fixed and can vary within a species and between populations.

Abalones have no operculum. The aperture of the shell is very wide and nacreous. The exterior of the shell is striated and dull.

The color of the shell is very variable from species to species, which may reflect the animal's diet. The animal shows fimbriated head-lobes.

The side-lobes are also fimbriated and cirrated. The rounded foot is very large. The radula has small median teeth, and the lateral teeth are single and beam-like.

About 70 uncini are present, with denticulated hooks, the first four very large. The soft body is coiled around the columellar muscle , and its insertion, instead of being on the columella, is on the middle of the inner wall of the shell.

The gills are symmetrical and both well developed. These snails cling solidly with their broad muscular foot to rocky surfaces at sublittoral depths, although some species such as Haliotis cracherodii used to be common in the intertidal zone.

Abalones reach maturity at a relatively small size. Their fecundity is high and increases with their size from 10, to 11 million eggs at a time.

The spermatozoa are filiform and pointed at one end, and the anterior end is a rounded head. The larvae are lecithotrophic.

The adults are herbivorous and feed with their rhipidoglossan radula on macroalgae , preferring red or brown algae. By weight, about one-third of the animal is edible meat, one-third is offal, and one-third is shell.

The shell of the abalone is exceptionally strong and is made of microscopic calcium carbonate tiles stacked like bricks.

Between the layers of tiles is a clingy protein substance. When the abalone shell is struck, the tiles slide instead of shattering and the protein stretches to absorb the energy of the blow.

Material scientists around the world are studying this tiled structure for insight into stronger ceramic products such as body armor. The number of species that are recognized within the genus Haliotis has fluctuated over time, and depends on the source that is consulted.

The number of recognized species ranges from 30 [3] to Those that have been reviewed tend to show that the abalone in general is declining in numbers, and will need protection throughout the globe.

Juveniles feed on microscopic algae. When juveniles reach about 5 mm in length they start feeding on larger species of algae.

They prefer drifting red algae. All rights reserved. ABN: 18 You may display, print or reproduce this material only in an unaltered format for your personal or non-commercial use, or for use within your organisation.

Apart from any use permitted under the Copyright Act , all other rights are reserved. Divers measure each abalone before removing from the reef and the deckhand remeasures each abalone and removes excess weed growth from the shell.

Sport harvesting of red abalone is permitted with a California fishing license and an abalone stamp card. In , the abalone card also came with a set of 24 tags.

This was reduced to 18 abalone per year in , and as of the limit has been reduced to 12, only nine of which may be taken south of Mendocino County.

Legal-size abalone must be tagged immediately. A person may be in possession of only three abalone at any given time.

As of , Abalone season is May to October, excluding July. Transportation of abalone may only legally occur while the abalone is still attached in the shell.

Sale of sport-obtained abalone is illegal, including the shell. Only red abalone may be taken, as black , white , pink , flat , green , and pinto abalone are protected by law.

That year, they extended the moratorium to last through April, An abalone diver is normally equipped with a thick wetsuit , including a hood, bootees , and gloves, and usually also a mask, snorkel , weight belt , abalone iron, and abalone gauge.

Alternatively, the rock picker can feel underneath rocks at low tides for abalone. Abalone are normally found on rocks near food sources such as kelp.

An abalone iron is used to pry the abalone from the rock before it has time to fully clamp down. Divers dive from boats, kayaks, tube floats, or directly off the shore.

The largest abalone recorded in California is The mollusc Concholepas concholepas is often sold in the United States under the name "Chilean abalone", though it is not an abalone, but a muricid.

Haliotis iris or blackfoot paua is the ubiquitous New Zealand paua , the highly polished nacre of which is extremely popular as souvenirs with its striking blue, green, and purple iridescence.

Haliotis australis and Haliotis virginea are also found in New Zealand waters, but are less popular than H.

Like all New Zealand shellfish, recreational harvesting of paua does not require a permit provided catch limits, size restrictions, and seasonal and local restrictions set by the Ministry for Primary Industries MPI are followed.

In addition, no person may be in possession, even on land, of more than 20 paua or more than 2. Paua can only be caught by free-diving; it is illegal to catch them using scuba gear.

An extensive global black market exists in collecting and exporting abalone meat. When such permits to harvest are abused, it is frequently difficult to police.

The limit is strictly enforced by roving Ministry for Primary Industries fishery officers with the backing of the New Zealand Police. Poaching is a major industry in New Zealand with many thousands being taken illegally, often undersized.

Convictions have resulted in seizure of diving gear, boats, and motor vehicles and fines and in rare cases, imprisonment. The largest abalone in South Africa, Haliotis midae , occurs along roughly two-thirds of the country's coastline.

Abalone-diving has been a recreational activity for many years, but stocks are currently being threatened by illegal commercial harvesting. For the last few years, however, no permits have been issued for collecting abalone, but commercial harvesting still continues as does illegal collection by syndicates.

Export permits are still required, however. The abalone meat from South Africa is prohibited for sale in the country to help reduce poaching; however, much of the illegally harvested meat is sold in Asian countries.

Ormers Haliotis tuberculata are considered a delicacy in the British Channel Islands as well as in adjacent areas of France , and are pursued with great alacrity by the locals.

This, and a recent lethal bacterial disease, [49] has led to a dramatic depletion in numbers since the latter half of the 19th century, and "ormering" is now strictly regulated in order to preserve stocks.

The gathering of ormers is now restricted to a number of 'ormering tides', from January 1 to April 30, which occur on the full or new moon and two days following.

No ormers may be taken from the beach that are under 80 millimetres 3. Gatherers are not allowed to wear wetsuits or even put their heads underwater.

Kempthorne-Leigh of Guernsey was arrested by a police officer in full diving gear when illegally diving for ormers. The highly iridescent inner nacre layer of the shell of abalone has traditionally been used as a decorative item, in jewelry , [5] buttons, and as inlay in furniture and in musical instruments such as on fret boards and binding of guitars, etc.

Abalone pearl jewelry is very popular in New Zealand and Australia, in no minor part due to the marketing and farming efforts of pearl companies.

Unlike the Oriental Natural, the Akoya pearl, and the South Sea and Tahitian cultured pearls, abalone pearls are not primarily judged by their roundness.

The inner shell of the abalone is an iridescent swirl of intense colours, ranging from deep cobalt blue and peacock green to purples, creams and pinks.

Therefore, each pearl, natural or cultured, will have its own unique collage of colours. The shells of abalone are occasionally used in New Age smudging ceremonies to catch falling ash.

They have also been used as incense burners. Abalone has been an important staple in native cultures around the world, specifically in Africa and on the North American West coast.

The meat was used as food, and the shell was used as currency for many tribes. Abalones have been identified as one of the many classes of organism threatened with extinction due to overfishing and the acidification of oceans from anthropogenic carbon dioxide , [54] as reduced pH erodes their shells.

In the Chilean Pacific coast, the species called loco Concholepas concholepas has a hard, black shell, and is eaten by many people.

Abalone have unique features: the shell is round, with two to three spirals. The last spiral is grown into a large "ear"-like shape, which explains the name 'ear-shell'.

The inside of the shell is shiny, from silvery white to green-red mother-of-pearl. Abalones can start to give birth at a small size.

Their fertility is high and increases with size from 10, to 11 million eggs at a time. Young albalones, called larvae , feed on plankton.

The adults eat plants and feed on algae. They like to eat red algae. The shell of the abalone is known for being very strong.

It is made of very tiny calcium carbonate tiles stacked like bricks. Between the layers of tiles is a sticky protein substance.

Allergic skin reactions and asthma attacks can happen when breathing the dust made when these tiles are broken down. The colorful inside part of the abalone shell can be used for decorative inlays , in guitars , for example.

Sport harvesting of red abalone is allowed with a California fishing license and an abalone stamp card.

Abalone may only be taken using breath-hold techniques: freediving or shorepicking.
