After a busy weekend it was Monday river diving time. There no one there! Bliss... Firstly the large Tenellia puti in the Gothum City Groove were not there anymore! Tenellia puti was out on the sand, I picked it up and put it a new hydroid home. Polycera sp. 14 a New Species was recorded today at Metropolis! Complete with the puffiest rhinophores. 4 hours of bliss...
