A single shore entry dive by Gary, Fran and Nevar of 240 minutes. Maximum depth 5.7 m, 20 C water temperature up to 12 m viz.

This is our first dive of June and just to be sure about it the water temp was 20C. Goniodoridella sp. 1, Cratena lineage and Unidentia remain the most common and with plenty of egg masses. Plocamopherus ceylonicus was recorded today as well with the back part of the dorsum chewed off which included the gills. And to top off another nice dive was another new species...a member of the Retusidae family - Pyrunculus phialus (A. Adams, 1862). And lastly, today was the coolest water temp this year 20C.
