Puri Jati is a black sand beach with an easy water entry, although you may have to ford the small fresh water stream to get to the water's edge. The black sand bottom slopes gradually out to a depth of about 10m, at which point the slope increases, leading more quickly to deeper water. On our two days of diving there, we only went to the edge of the steeper slope, spending most of our time in the shallows on top. The flat sand had sea grass close to the beach, giving way to a large number of a couple of kinds of solitary corals that have a most peculiar symbiotic relationship with a sipunculid worm living in an empty gastropod shell. The coral grows on the shell, which becomes occupied by the worm, who is then able to provide some mobility to the coral and keep it from being buried in the soft sediment. There were a couple of obstructions--poles with concrete bases and old tires--placed out there to attract marine life, and they were often surrounded by fish and other animals. But much of the life was just randomly distributed on the sand. Among many other things, we saw frogfish (Antennarius pictus), ornate ghost pipefish (Solenostomus paradoxus), more marine catfish (Plotosus lineatus), sea pens, cuttlefish, various scorpaenids including Inimicus didactylus and Parapterois heterura, lots of young Pterois volitans lionfish, commensal emperor shrimp (Periclimenes imperator) on sea cucumbers, various burrowing crabs and echinoids, and a lot more. We saw only one nudibranch species, three specimens of an interesting (probably) Godiva species moving among the eel grass near the beach. Like many beaches on the north coast of Bali, the shore was lined with traditional, brightly painted Balinese outriggers called jukung.
A fresh water stream cut through the beach and flowed into the ocean. Perhaps this accounts in part for the interesting animals.
The small parking area held a couple of vans from other dive groups.
Our dive guide Romon knew the area well. His sharp eyes picked out a tiny pipehorse that was hard to see even when you knew it was there.
