"The Japanese sea urchin, or uni, is a dark spiky, round sea creature that varies in size, depending on type, from 1-1/4 to 1-1/2 inch to over 4 inches in diameter. Only the ovaries are eaten. Fresh uni is one of the regular items for sushi toppings and is also used for making hors d'oeuvres. It provides an interesting golden coating for some seafood, such as squid, that is to be grilled and also an unusual dressing for many shellfish. Salted uni is also available."

The male roe, or testes, are more likely to be orange in color rather than yellow, as the female roe, or ovaries.

We use the word roe because it sounds nicer."
