Biology – BIOL1000
Abstract
The black abalone or Haliotis cracherodii as it is known from its genus species designation is a large, edible sea snail. The shell coloring on the outside is a dark blue or green or black, and the interior is a pearly iridescent colour. The shell shape is spiraled and very smooth. It uses a muscular foot to adhere itself to rock bases, and is fairly nocturnal for its own protection. It is lives along the coast of California down to parts of Mexico. On January 14, 2009, the black abalone was put on the Endangered Species List. It is a dying species because of human involvement and is greatly affected by a disease known as Withering Syndrome.
