The sea slug of the Jorunna parva

The sea slug of the Jorunna parva species was discovered back in 1938 by the Japanese marine biologist Kikutaro Baba, but then the information did not spread beyond publications in scientific journals.
Now the whole world has learned about the unusual slug: first, in the Japanese segment of the Internet, and then everywhere, videos and photographs of the mollusk, which received the unofficial name of the sea rabbit, began to appear.
