A town in western Japan has turned the hatpin urchin, seen as a nuisance of the ocean as it devours seaweed, into a local delicacy.

Ainan in Ehime Prefecture has released a variety of the sea urchin fed with scraps of the town's signature agricultural products of broccoli and citrus.

Aptly named Uniccoli — a portmanteau of uni, the Japanese name for sea urchins, and broccoli — the product was developed in hopes of improving the local fishing environment, with the United Nations' sustainable development goals in mind.
