What is the evolutionary dilemma regarding Osedax? [5], Smith and his colleagues suggested in 1989 that such species may use whale falls as stepping-stones to extend their range across multiple chemosynthetic communities. However, in deeper water (depths of 2,000 m/6,600 ft or greater), fewer scavenger species exist, and the carcass can provide sustenance for a complex localized ecosystem over periods of decades.
