Opihi, limpets with a cone-like shell, have been overharvested for more than a century. In 1900, roughly 150,000 pounds of opihi were harvested for commercial sale in Hawaii. By 1944, opihi sales were down to 13,000 pounds. “The fishery had crashed,” says Dr. Chris Bird, a marine ecologist with The Hawaii Institute of Marine Biology (HIMB). Bird explains that the value of opihi is increasing due to the fact they’re getting harder and harder to find. In 2009, opihi were the fifth most expensive seafood harvested in Hawaiian waters, at $6.80 per pound wholesale, according to NOAA and the Hawaii Division of Aquatic Resources. (...)
Opihi Facts

Opihi Makaiauli
(Cellana exarata) want to be splashed, and don’t mind being dry between tides. The low ribs of their shells are dark and their troughs light. They grow to about two inches across.
Opihi Alinalina
(Cellana sandwichensis) crave constant splash or surge and can’t tolerate drying out for long periods. Their shells grow to about 2 and a half inches across and have a scalloped edge that was used by Hawaiians for shredding coconut meat.
Opihi Koele
(Cellana talcosa) are sometimes submerged and can live in depths of up to 10 feet. Koele are the largest of Hawaiian opihi, growing up to four inches across. Their shells are smooth and thick with a low profile.

Opihi Facts
Hawaii has three endemic species of opihi and each live in different sections along the rocky intertidal zone. They’re also very specific about what they like—and what they don’t.
