More about abalone

Abalone breed by releasing their eggs, or sperm, depending on their sex, into the water, through the holes in their shells. The female produces about 11 million eggs. The male sperm fertilizes the female eggs, which eventually develop into larvae, which float in the plankton.

After about seven days, the larvae sink to the seabed and begin to develop into adults. They will develop and grow for two years before they themselves are able to breed.

As you may imagine, only a small portion of this larvae survives to maturity. Many are swept away on ocean currents, others are eaten by predators such as starfish, crabs and fish.

A is for Abalone



Abalone are mollusks. They are found on seashores and shallow coastal waters in those parts of the world that have warm water, a rocky floor, and plenty of seaweed (their food of choice).

Abalones are part of a group of mollusks called gastropods. Gastropods have coiled shells. An abalone's shell is wide and flat and is used as a shield over its back.

The ridged outer surface of the shell is typically encrusted with algae, which allows it to blend into the surrounding rocks. The body within the shell is simple. It clings to and crawls across rocks using a "foot" - a large muscle. Around this foot are tentacles that detect chemicals in the water. It also has a pair of simple eyes, which can distinguish between light and dark.

Abalone are a popular seafood. Below is a video a diver made of hunting red abalone off the coast of Sonoma, CA for his dinner.
