Brook Lamprey
Ken sent me these pictures taken today at Darley Bridge of Brook Lamprey. From Ken's description it sounded like they were involved in some sort of display/spawning. This is not a species with which I'm familiar at all but I'll take a look tomorrow.

Most interesting! I saw almost exactly the same here this afternoon, in NW France. I assumed that one size/colour was male and the other the female, but nothing I can find in my books nor even on-line says that the sexes are different colours or sizes.
ReplyDeleteAlso, not apparent in the photo above, but here the darker ones appeared to be distinctly smaller than the bigger much lighter ones, but they; One bigger light one with one or even two smaller dark ones; were most certainly engaging in spawning behaviour, i.e. intertwining, and the darker ones hanging on to stones with their suckers and 'digging' in/moving the very small gravel with their tails. Stupidly I took stills rather than filming. Hopefully they may be there again tomorrow, and I can film.
