Aplysia californica is a curious beast indeed. The California sea hare is a species of sea slug; a hermaphroditic gastropod mollusc that feeds on seaweed and occasionally squirts ink if you piss it off. Charming little chap, really.

It's a bizarre feeling, yet it’s one that we’ve all probably experienced, at one time or another.  

Whether it’s the brush of a feather-duster, or a friend’s fingers under your chin, a great many of us are ticklish.
