It is difficult to begin to count the number of native and endemic invertebrate species present in Galapagos, with new species being discovered by CDF scientists all the time. Invertebrates play crucial roles within the ecosystems of Galapagos, interacting with both plant and higher fauna species. Land snails are fascinating examples of adaptive radiation, the rapid development of new species to fill a niche within a particular ecosystem. More than 65 species are known to have evolved from a single ancestor. The islands are just as rich in insects such as moths, butterflies and ants, as well as many other types of invertebrates. It is sadly true that many invertebrate species have already become extinct, a result of human activities including habitat destruction and the introduction of alien species. Approaches aiming to maintain the ecosystems of Galapagos will hopefully help preserve the endemic and native invertebrates found there.
