Variable blenny. Plymouth - August 2023

Variable (or ringneck) blenny on the Breakwater fort
A less often sighted blenny in UK waters but a number of them were seen darting about the seabed near the breakwater fort in Plymouth.

This was the first time I have photographed this fish. Whilst I might have seen this fish before I can't be sure, so I'm counting this as a new species for me.
