Other desert keystone species include the desert tortoise of the Mojave (which digs burrows that other animals rely on for protection from predators and the desert heat) and the Australian dingo, which preys on both predators in the middle of the food chain, like invasive red foxes and feral cats, as well as a wide range of herbivores (e.g., kangaroos), helping to keep the Australian outback intact. Pummeled by waves and ocean currents, coral exoskeletons can experience bioerosion. For all the species it supports, the six-ounce seabird relies on just one food source: microscopic crustaceans called copepods that thrive west of Svalbard, where cold Arctic waters mix with the warm, salty Atlantic current.
