Fun Abalone Facts For Kids

Belonging to the genus Haliotis and therefore aptly called the escargot of the sea, abalones are gastropod mollusks considered culinary delicacy the world over, especially in parts of Latin America. Abalones are normally found in the cold waters of Southern California, South Africa, New Zealand, western North America, and the Channel Islands. Abalones are relentlessly hunted.

The mortality rate of the egg and the sperm is approximately 99% due to the fierce ocean currents and unpredictable underwater temperatures. Should the egg actually get fertilized, filter-feeding animals like clams, krill, and sponges lie in wait.

If the odds are beaten still, and the larva matures into a juvenile, nocturnal predators like crabs, lobsters, and octopuses await them in the dead of the night. You would think that when the transition from juvenile to adult takes place, the poor abalone would be safe.

But the biggest plague upon the wild abalone is also the plague devastating the rest of the planet. Mankind. Read on for more abalone facts for kids, details about the kingdom, phylum, class, subclass, white abalone, red abalone, and a lot more.

Abalone Interesting Facts

What type of animal is an abalone?

The aforementioned sea snail wild abalone belongs to the Haliotidae family, genus Haliotis and is a univalve mollusk akin to the escargot it is often compared to. The abalone species have evolved complex appendages to prevent predation, like knobs and spines. The geometrical construction that nature has bestowed upon abalone is nothing shy of magic.

The shell of the abalone is seen in a variety of iridescent blue, green, and purple. This sheen, coupled with the exquisite meat makes abalone a very desirable commodity.

The symmetrical, open spiral whorls increase in length exponential rate and begin resembling an ear. They are therefore called ear shells. The last ear shell occupies 90% of the total abalone shells volume.

What class of animal does an abalone belong to?

Abalones belong to the class Gastropoda, which comprises 40,000 species of snails and slugs. They are found in the cold waters of the ocean and on land.

Most gastropods are an essential part of the gourmet cooking industry. They are used for research purposes in early evolutionary studies. They come in all shapes and sizes and genders, some are asexual and some, like, Lymnaea stagnalis, are hermaphrodites.

How many abalones are there in the world?

White abalone, or Haliotis sorenseni, were estimated to have a population of two to four million, back in the 1970s, however, due to excessive and unrestricted fishing norms, only a few thousand white abalones remain. Alas, as the abalone smartens up, so do their predators.

Octopuses and shellfish are replaced by more efficient aggressors like the bat ray and the otter.

The white abalone species faces the threat of extinction within 10 years unless immediate action, especially in terms of fishing restrictions, is taken. Red abalones are another species that exist along with Haliotis tuberculata.

Where does an abalone live?

Abalones are found in the waters of every continent, except for Antarctica.

What is an abalone's habitat?

Living abalones are marine reef dwellers, seeking out rocks near food sources like (kelp and other algae) and crevices to hide within and move about occasionally by virtue of their muscular foot. White abalones are indigenous to the open rock and boulder habitats of the coast of North America.

Black abalones, or Haliotis cracherodii, reside on rocky substrates in intertidal and shallow subtidal reefs of Southern California.

Who do abalones live with?

Abalones are found in clusters.

How long does an abalone live?

An abalone lives anywhere from 25-40 years, with each type of abalone falling somewhere within this spectrum.

How do they reproduce?

Most species of abalone, like the red abalone and white shell abalones, spawn all year round. Low tides for abalone reproduction are preferred.

The males release up to 10 billion sperm and the females release several million eggs at a time. The rate of reproduction as well as the rate of success is directly proportional to the water temperature. However, for those suffering from limited ability, the mating season begins in July and lasts until October.

The sperm and the eggs are released into the ocean at the same time. They are carried by the current until they reach the larvae stage and anchor themselves onto their rocks.

What is their conservation status?

Wild abalones, also called abalones from the rock, are Endangered species.

In North America, sport harvesting of red abalone is permitted. It requires a fishing license, with the daily limit set at three per diver and a minimum abalone shell length of 7 in (180 mm).

Paua, as it’s called in New Zealand, is harvested recreationally, with the daily limit being 10 per diver with a minimum abalone shell length of 5 in (125 mm).

The problem of illegal abalone poaching for commercial harvest in South Africa is worse than ever before, and wild abalone has replaced ivory for the title of white gold.
