The West Indian sea egg: Tripneustes ventricosus (Lamarck, 1816), also known as the Sea Egg or White Sea Urchin, is an edible sea urchin species native to the tropical and subtropical waters of the western Atlantic Ocean. It is widely distributed throughout the Caribbean Sea, the Bahamas, and the coastal waters of Florida, where it has long been valued as a traditional seafood resource.
This species is relatively large, reaching a test diameter of 10–15 cm. It is characterized by a dark-colored test, ranging from black and deep purple to reddish-brown, covered with short white spines. Like several related species, it often carries pieces of seagrass, shell fragments, and other debris on its body as camouflage and protection from intense sunlight in shallow waters.
For culinary purposes, the edible portion is the gonad, commonly known as uni. The roe is typically bright yellow to orange in color and is prized for its rich sweetness, creamy texture, and mild oceanic aroma. Feeding primarily on seagrasses and marine algae, the species develops a delicate flavor profile that is highly appreciated throughout the Caribbean.
The West Indian sea egg has supported important local fisheries, particularly in Barbados and other Caribbean islands. However, intensive harvesting during the twentieth century contributed to significant population declines in some regions. As a result, seasonal fishing closures, conservation measures, and aquaculture-based restocking programs have been implemented to help rebuild natural populations.
Although rarely encountered in Japanese sushi restaurants, Tripneustes ventricosus remains one of the most culturally and commercially important edible sea urchins in the Caribbean and is highly regarded for the quality of its uni.
