Steve is in town and we need to get in the river. Some interesting species were recorded today. We haven't seen Gymnodoris amakusana in quite a while. Two Lophodoris sp. 1 and Placida kevinleei great to see. Knoutsodonta maugeansis with eggs was a treasure especially on the black slate. A new species was also recorded today, the shell of Haminoea sp. 20 at about 2 mm. Cratena pawarshindeorum was still around, one animalk was being eatin by what appeared to be a a tube worm, so I plucked it out and it happily crawled away with about 80% of it body!
