Rhinopias prefer reefs exposed to swells and currents. They mimic crinoids so to find one a diver should carefully inspect all the crinoids of the reef. I have found them in waters generally shallower than 45 feet but there was one in Milne Bay at 67 feet. I have seen Rhinopias aphanes in green , black and pink and generally when you find one, there is likely to be the mate for the pair in the area. A head on shot of this fish emphasizes the lacy adornment.
Anemone fish exemplify a symbiotic relationship between a fish and an invertebrate animal.
The anemone fish benefit from the relationship because the anemone, which would normally consume a fish by stinging it and then eating it, provides protection both for the fish and its eggs. The anemone fish has developed an immunity over time to the anemone sting by incorporating in its slime the proteins of the anemone itself. The anemone fish Amphiprion Ocellaris is also called a clownfish because of its constant bouncing around within the host anemone. Many people incorrectly call this fish a Percula Clown when in fact Amphiprion Percula is a different albeit similar species. There are many more invertebrates than their are vertebrate animals.
