Tropidurus albemarlensis

Description:

found on the santa cruz island of galapagos. There are seven different species of Tropidurus, lava lizards, found in the Galápagos. The seven different species are T. grayi, T. bivattatus, T. pacificus, T. habellii, T. delanonis, T. albemarlensis, and T. duncanensis. According to Michael H. Jackson in his 1993 field guide, "One species occurs on all the central and western islands (which were perhaps connected during periods of lower sea levels), while one species each occurs on the six other more peripheral islands." Evidence supporting the Theory of Evolution is found when observing the lava lizards of different islands. It is believed that all of the different species of lava lizards evolved from one single species.
