2.2 The marine environment is crucially important
to the survival of a large number of land or coastal organisms. Reptiles
(sea turtles and the native marine iguanas), mammals (two endemic
seal species and a wide variety of cetaceans) and sea birds (Galapagos
penguins, albatross, petrels, flightless cormorant, boobies, seagulls,
pelicans and frigates, including a surprisingly high number of endemic
species) depend not only on the inshore waters but the whole area
of the Galapagos marine reserve and beyond, so important are the "bajos",
the Equatorial Front, the upwelling zones of the Cromwell current
and the equatorial currents as feeding grounds.
