An impressive and robust reptile, the Barrington land iguana is a slightly lesser-known relative of the famous marine iguanas which inhabit the Galápagos. Reaching lengths of over one metre and with a ridge of spines running from the top of the head down the back (2), the appearance of this iguana evokes the time of the dinosaurs (4). The yellow head has numerous conspicuous, large scales, much larger than those which cover the body, and a flap of skin hangs loosely from the throat. The body is largely pale yellow with brown underparts (2). Two species of land iguana are found on the Galápagos Islands (5); this species can be distinguished from its close relative Conolophus subcristatus
by being more uniformly yellow in colour and having more pronounced spines (4).
