The Abalone, sometimes called "sea ears", because of his shape, is a marine mollusc that spends its life hang on a rock, eating seeweed. Its unique shell, well known thanks to its beautiful mother of pearl, protects it angainst predators and sunlight. Haliotis Cracherodii is a unusual abalone, slightly more modest than his cousins, has an elegant shell dark green and blue colored, which encloses a silvery interior with pale pinkish and greenish iridescence. And especially when polished. Unfortunately, the black abalone is affected by a disease that dangerously decreases their number.
