So what did the footage reveal? It revealed only a short glimpse into the lives of billfish but, as is to be expected billfish live in a very blue world. In addition, to the footage an on-board depth/temperature recorder register each fish making quick deep dive away from the boat followed by a series of undulating dives from 50-70 feet. As they made these dives they swam through as described by Crittercam creator, Greg Marshall, a "bouillabaisse" of planktonic life. Watching these fish swim away from the boat, one assumes that they swim through a clear world but, in reality they spend their lives in a pelagic soup. In addition, the camera placement on the black marlin allowed a view of the animal's eye which is incredibly active. The eye is continually moving, presumably trying to pick up on the movement of their next meal or a potential predator. These initial deployments did not reveal feeding or social behaviors but, subsequent use of the cameras will be devoted to longer deployment times in an attempt to unlock further secrets of billfish behavior.
