Definitions

Etymology: The name comes from the ancient Greek "akmē," which meant a point, a peak, or the edge of a blade. The limpets it names have tall, cone-shaped shells that rise to a sharp tip, and that tip gave the name its sense. Naturalists took the Greek term and applied it to the group, so it is a scientific coinage rather than an old name for the animal. Because it was made for classification, it is a technical term with no popular history behind it. Its meaning rests on the shape of the shell: the pointed summit that the Greek word described.

Synonyms: limpet, mollusk, gastropod, sea snail
