Went on a good dive at Silver Steps in Falmouth yesterday.The visibility wasn’t that great, but for the most part we were rummaging under overhangs in gulleys just off the coast. Sweeping aside the kelp reveals many fine red seaweeds, sponges, bryozoans and small Devonshire cupcorals. We saw the ubiquitous Tompot blenny Parablennius gattorugine as well as a Bib (or Pout) Trisopterus luscus. Overhead there were many Sandeels as well as some relatively large Pollock Pollachius pollachius hunting them:However, there was a much more remarkable fish we spotted, namely the Black-faced blenny Tripterygion delaisi. We first saw a male, bright yellow with a black head and beautifully skyblue-lined fins. Only after a while we noticed the inconspicuously coloured female. The male is coured this way only in the breeding season. (We later saw another larger male, no female, although that was probably closeby.) My fish guides tell me that this Mediterranean species was first spotted in the UK in the 70s and that it is currently present in only two or three locations on the South West coast. Some browsing on the web has told me that in recent years they have been recorded in more locations but they still must be relatively rare (and I therefore won’t be attempting to catch them). Global warming will likely extend the range of this species more firmly northwards; one of the very few positive effects of our addicition to carbon… Lastly, I now managed to get a shot of the Candy striped flatworm Prostheceraeus vittatus:
cool black head fish!
