The population that has often been known as the Galápagos green turtle have been recorded and observed in the Galápagos as far back as the 17th century by William Dampier. Not much attention has been paid to them due to the overwhelming research done on the Galápagos giant tortoises. Only over the last 30 years have extensive studies been performed covering the behaviors of the Galápagos green turtles. Much of the debate that has surrounded them recently is over the binomial classification of the species. At one point the name "Chelonia agassizii" was applied to this population as a separate species. Analysis of mitochondrial and nuclear DNA of 15 nesting beaches. however has demonstrated that there is not only no significant distinction of this population but that it would be paraphyletic to recognise it. As such the species name "Chelonia agassizzii" is considered a junior synonym of "Chelonia mydas" as such it is considered as a local cariant of the populations of the East Pacific waters and those of other nesting areas.
