Found beneath a rock at low water along Uig Bay, Isle of Skye on 11th Feb 2017. Butterfish are quite common here, I found 4 within an hour of searching under rocks (lacking proper rockpools up here) but this is the first one I've found with eggs. Judging by the gravid body I'd say she's still got a fair few more inside! Butterfish are unusual in that both parents take turns guarding the eggs.
