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.[3][4]
Taxonomy
[edit]The species was first described by American zoologist Edmund Heller in 1903. Some authorities have questioned whether C. pallidus is a valid species in its own right or merely a variant or subspecies of the Galapagos land iguana found on other islands in the Galapagos.[5]
Etymology
[edit]Its specific name, pallidus, is Latin for "pale", denoting its lighter coloration than C. subcristatus.
Morphology
[edit]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.[3]
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).[6] Being cold-blooded, it absorbs heat from the sun basking on volcanic rocks and at night sleep in burrows to conserve its body heat.[6] 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.[3][7]
Diet
[edit]Santa Fe land iguanas are primarily herbivorous, however some individuals have shown that they are opportunistic carnivores supplementing their diet with insects, centipedes and carrion.[3] Because fresh water is scarce on the islands they inhabit, land iguanas obtain the majority of their moisture from the prickly-pear cactus that makes up 80% of its diet: fruit, flowers, pads, and even spines.[3][6] During the rainy season they will drink from available standing pools of water and feast on yellow flowers of the genus Portulaca.[6][7]
