Abalone is an ocean-dwelling gastropod, a mollusk with head bearing tentacles, eyes and a foot. They are members of the Haliotidae family and genus Haliotis, which means sea-ear, referring to the flattened shape of the shell. They secrete nacre, microscopic calcium carbonate tiles from the epithelial cells of their mantle tissue. The material is a mineral with a specific crystal structure called aragonite. The inner nacreous layer of the mollusk has an iridescent play of color which is commonly called “mother of pearl”. The color banding on abalone shells is due to changes in the types of algae eaten.
(clams, oysters and mussels are in the family)
