Chelonoidis niger vicina, commonly known as the Cerro Azul giant tortoise, Iguana Cove tortoise or the Isabela Island giant tortoise, is a subspecies of Galápagos tortoise endemic to Isabela Island in the Galápagos.[1]
Population history
[edit]This population was depleted by seamen in the last 200 years and by extensive slaughter in the late 1950s and 1960s by employees of cattle companies based at Iguana Cove. Their population is thought to overlap with Chelonoidis niger guentheri.
Description
[edit]It has a thick, heavy shell intermediate between saddle-backed and domed, and not appreciably narrowed anteriorly. Males are larger and more saddle-backed; females are more domed. Until eradication programs, virtually all nests and hatchlings were destroyed by black rats, pigs, dogs, and cats.[3]
