Japan and...SEA BUNNIES?
/That's what the Japanese on Twitter are calling this adorable little sea slug— Sea Bun, or Sea Bunny. They've hit Japanese Twitter like a rampaging storm.
In reality though, this is a real sea creature. It's scientific name is Jorunna parva, and the long, bunny like "ears" it has are actually a part of it's body called "rhinophores", which it uses for taste and sensing movement as they live on the sea floor. Jorunna parva also feature a sort of "bushy tail" on their bodies as well. Native to the Indian Ocean, it seems though that a lot of Japanese people are starting to go diving more to go and look at the sea buns.
Don't believe sea slugs are now a thing in Japan? Just watch this video by ダイブストアエグザイル.
