Meet The Sea Bunnies, The Strange Sea Creatures Japan Has Fallen In Love With

Despite its cute and cuddly appearance, this little sea creature is actually a kind of slug. When you hear the word “slug” your first reaction probably isn’t “adorable”, but after checking out these Jorunna parva sea slugs, you might feel differently.

The sea bunny's "ears," or the two antenna-like structures on top of its head, are most definitely sensory organs. Called rhinophores, they detect chemicals in the water that helps sea bunnies find food and mates, says Valdés. The rhinophores are covered in little flaps that boost their detection capabilities, allowing J. parva to sense its environment very efficiently. The structure on the sea bunny's behind that looks like a little "flower" are its gills.
