Abalone

Abalone are marine gastropod mollusks in the genus Haliotis, known for their flattened ear-shaped shells, rows of respiratory holes, and pearly inner layer.

Updated July 30, 20261 min readCited sources

Abalone are marine sea snails—edible mollusks known for their flattened ear-shaped shells, iridescent mother-of-pearl interior, and a distinctive row of respiratory holes along the edge.

What it is

Abalone belong to the genus Haliotis and are gastropod mollusks found in warm seas worldwide. They cling to rocky coastal waters, grazing on algae and seaweed with a muscular foot. Their shells are prized for nacre, or mother-of-pearl, used in jewelry and decoration.

Why it matters

Overfishing, disease, and habitat loss have pushed some wild abalone populations into decline, leading to protective measures in several regions—including Canada’s Pacific coast. Most commercial abalone is now farmed, making aquaculture a key source for the seafood market.

Key details

Abalone is considered a delicacy in cuisines worldwide, especially East Asian cooking. It is often tenderized and quickly cooked to avoid toughness. Conservation rules on wild harvesting vary by species and area, with some abalone species listed as threatened or endangered.

In short

  • Abalone are sea snails (genus Haliotis) with flattened, ear-shaped shells and mother-of-pearl interiors.
  • They are edible and used in various cuisines, but overharvesting has made many wild stocks protected or endangered.
  • Most abalone sold today is farmed rather than wild-caught.
  • Canadian Pacific waters have some species under conservation due to population declines.
Canadian angle

Abalone is relevant to Canadian readers through seafood consumption, marine conservation, and fisheries management on the Pacific coast, where some abalone species have been protected because of population decline.

Quick questions

What is abalone?
Abalone are marine sea snails with a flattened shell, a row of respiratory holes, and a nacreous interior. They are edible and often used in seafood dishes.
How to cook abalone?
Abalone is typically tenderized first, then quickly sautéed, steamed, grilled, or sliced thin for soups. Overcooking makes it tough.
Where to buy abalone?
Abalone is available through seafood markets, fishmongers, specialty grocers, and aquaculture suppliers. Availability depends on local laws and whether it is farmed or wild.
