the mantle more or less envelops the shell, giving it a slug-like
appearance in life. The family is especially prolific in cool
waters. |

Abalone
| Abalone have bowl- or ear-like shells with a row of pores. The
interior is lined with mother-of-pearl. Large species have been
depleted in many parts of their natural range due to fishing. A
few species are being raised in captivity for sale or stock
enhancement. None occur in Hawaii. |
