These are some of the features that characterize a remote archipelago like our own, but one of the most important is that which can be called "ecological naïveté". In isolated places such as the Galapagos, there is what is known as a disharmonic distribution, where certain faunal groups are over -represented, and others virtually absent. One of the more conspicuous groups missing here are the large mammalian predators, so many species have genetically been bred out of their fear instinct, over the aeons.
This phenomenon can be observed wherever we go, even to the edges of the sea, where a renowned and feared predator such as the shark will swirl around one's ankles in the dozens, in a totally harmless fashion. One of our naturalists, Cecibel, actually counted over fifty of these animals in the shallows today, a record by even Galapagos standards!
