Located directly across the street from the Cabras/Piti power plant are two very shallow and distinctive "channels" in the reef. The channel just west of the Seaman's Club is the inflow water supply for the plant, The 2nd channel, located directly across the street from the main entrance to the plant, is the outflow channel.
For years these were used as training sites for divers, and still offer some very easy dives and quite a variety of marine life. They are also very good for snorkeling.
The best areas to observe the many small critters here are along the sides of both channels.
Hell's Fire Anemone: these are found in the sand areas on the side and bottom of these channels. These anemones are so named 'stinging sea anemones' because of their capacity to sting humans badly. Although all anemones have stinging cells or nematocyst found in their tentacles, these anemones have a dangerous sting that is extremely powerful and is very painful.
The Hell's Fire Anemone has tentacles with a leaf shaped or feather-like appearance, thus they are also known as the Pinnate Anemone. They bury their foot and body in the sand with only their oral disc and tentacles emerging. When disturbed they can retract their entire body into the sand and be virtually invisible.
