Air-breathing visitors to seamounts: Marine mammals Kristin Kaschner
Abstract Pinnipeds and cetaceans are widely reported as more abundant in the vicinity of abrupt topographies like seamounts, yet there are few rigorous quantitative analyses. Some species such as the Hawaiian monk and Galapagos fur seals, Commersons and spinner dolphins, with slope or mesopelagic foraging habits, are characteristic of island arcs with many seamounts. Elephant and crabeater seals and beaked whales also tend to forage at seamounts, while Common dolphins, Bottlenose whales, Risso’s dolphin, Dall’s porpoise and pilot whales appear to be associated with strong bathymetric gradients, including seamounts. Here, a global habitat suitability model is used to forecast local abundances of marine mammal species by species. Results show a significant association of marine mammal abundance with seamount-rich locations.
