Lately there has been a lot of swell and wind and with inclement weather coming time to check it out. Upon descent the water column was thick with particulate. The sun was out when I entered and a short time later it all became rather dark making seeing details almost nil...rain moved in!

Get in while the going is great...lots of nudibranchs and clear water. Saw some species I didn't see Monday and didn't see some species I saw on Monday! A juvenile and adult Pleurobranchus peronii were spotted today. Nice to Plocamopherus ceylonicus from under a rock. Tenellia puellula was a treat! Have seen this before and now I am separating it from Tenellia sibogae - Tenellia sp. 80 New Species with white based rhinophores and white spots on the cerata. As I thought another great dive in this magnificent river.
