Sea Bunnies

When you think sea slugs I bet the last word that comes to mind is “cute”. Slugs are easily one of the grossest animals in the world, or so I used to believe. Meet the Jorunna parva, a tiny Indo-Pacific sea slug that’s decked out in the cutest colors. However, despite their visual similarity to bunnies, they share little in common.

Their soft fur-like appearance is actually caused by groups of tiny rods called caryophyllidia that bunch around black nubs. Their “ears” are rhinophores, and they help detect chemicals instead of sounds. Although they may look cute and fluffy they’re also very toxic so you’ll have to be content to admire them from a distance.

From this angle it’s hard to see anything but a cute little bunny-rabbit.

In 2015 they were all the rage on Japan’s Twitter.

Unfortunately, they have very short life spans, and typically only live for a few months.

Sea Bunnies are hermaphrodites and can’t be distinguished by sex. When they mate, both parties are impregnated.

Their toxicity comes form the food they eat, and serves as its only means of defense.

Technically they belong to a category of slugs amusingly known as nudibranchs.

Once again it goes to show that you can’t judge a book by its cover.
