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]
