Conolophus pallidus (the Santa Fe land iguana or Barrington land iguana) is a species of lizard in the family Iguanidae. It is one of three species in the genus Conolophus and is endemic to Santa Fe Island in the Galapagos. The Santa Fe land iguana is similar to the Galapagos land iguana except that the Santa Fe land iguana is paler yellow with a longer more tapered snout and more pronounced dorsal spines. The Santa Fe land iguana grows to a total length (including tail) of 0.91 m (3 ft) with a body weight of up to 11 kg (25 lb).[4] Being cold-blooded, it absorbs heat from the sun basking on volcanic rocks and at night sleep in burrows to conserve its body heat. These iguanas also enjoy a symbiotic relationship with the island's finches; the birds remove parasites and ticks, providing relief to the iguana and food for the birds.
