Just meters from the shores of the Japanese islands of Okinawa, a colorful array of coral reefs plays host to a wealth of amazing sea creatures. Two new species of pygmy squids have recently been discovered amongst them, and they’re pretty adorable to boot.

The new species were dubbed the Ryukyuan Pygmy Squid and Hannan’s Pygmy Squid, the latter of which was named after one of the underwater photographers who captured it and represents a whole new genus of squid. Their scientific names, however, were inspired by Japanese folklore.

Idiosepius kijimuna (the Ryukyuan), which has some red coloration, spends its time in the seagrass forests close to the shore. As a result, it was aptly named after Kijimuna, which are small, red-headed fairies that are said to live in Okinawa’s banyan trees.
