Found here and only here, so endemic to Norfolk Island, the Norfolk Island blenny, Parablennius serratolineatus, is a teeny, little shy guy, who hangs out quite a bit at one end of Slaughter Bay and also in Cemetery. You’ll see them elsewhere, of course, but those are the places where I can almost guarantee you will find them.

I’ve often spotted them sheltering among the spines of sea urchins. About 10 to 13 mm in length, with a broad dark stripe and some faint brown spots on their head, once you’ve seen one, you’ll keep seeing them.

They are so localised that they are very vulnerable to habitat degradation and possible effects of climate change.
