Sheep Of The Sea Are Cutest Slugs We've Ever Seen

It’s a sheep! It’s a cow! No, it’s Costasiella kuroshimae (or ‘Leaf Sheep’ for short). This adorable little sea slug, whose beady eyes and cute feelers make it look like a cartoon sea sheep, feeds on algae – just like the real thing.

The unique sea slug with big beady eyes, a flat face and little feelers that resemble hands looks like a cartoon sheep of sorts, hence how it earned the nickname 'leaf sheep'. Instead of chowing down on grass like real land-based sheep, there's nothing this underwater creature loves more than eating algae.
