Cellana sandwicensis

Cellana sandwicensis is a species of limpet, a type of marine gastropod in the family Nacellidae. It is endemic to the Hawaiian Islands, where it is known as the Hawaiian limpet or 'opihi in the native Hawaiian language.

Taxonomy

The Cellana sandwicensis was first described by the British malacologist Lovell Augustus Reeve in 1855. It belongs to the genus Cellana, which includes about 60 species of true limpets. The species name "sandwicensis" refers to the "Sandwich Islands," an old name for the Hawaiian Islands.

Description

Cellana sandwicensis has a conical shell, which is characteristic of limpets. The shell is usually less than 5 cm in diameter. The color varies from black to brown, often with radial streaks or bands. The interior of the shell is white with a blue or green tinge.

Habitat and distribution

This species is endemic to the Hawaiian Islands. It is found on rocky shores, where it grazes on algae. It is most common on the windward sides of the islands, where the surf is heavy.

Ecology

Cellana sandwicensis plays a crucial role in the ecosystem by controlling the growth of algae on the rocks where it lives. It is also an important food source for a variety of predators, including humans.

Human use

In Hawaii, Cellana sandwicensis is harvested for food. It is considered a delicacy and is often eaten raw or cooked in a variety of dishes. However, overharvesting has led to a decline in populations in some areas.

Conservation

While Cellana sandwicensis is not currently listed as endangered, its populations are monitored due to concerns about overharvesting. Conservation efforts include regulations on harvesting and public education about the importance of this species to the ecosystem.
