Male and female sea urchins are easily induced to shed massive numbers of eggs or sperm. The eggs are mature at release and are fertilized externally simply by mixing egg and sperm. The resulting embryos are optically transparent and develop synchronously in nothing more than sea water.

Can you eat sea urchin eggs?

They're the edible parts of the sea urchin. Take a spoon and scrape each one out. The gonads are also called roe, though this isn't technically correct because roe refers to a mass of eggs inside a fish. The gonads are the only edible parts of the urchin, so don't eat anything else inside the shell.

Do sea urchins produce eggs?

Sea urchins reproduce by sending clouds of eggs and sperm into the water. Millions of larvae are formed, but only a handful make it back to the shoreline to grow into adults.
