Galapagos Tortoise (Geochelone nigra)

The Galapagos tortoise (Geochelone nigra) is the largest of all living tortoises, reaching lengths of up to 4 feet and weights of over 350 lbs. Galapagos tortoises have long lifespans often living for over 100 years. These reptiles are vulnerable and suffer from the threats of introduced species. Cats and rats prey on young tortoises while cattle and goats compete for the tortoise's food source.

The Galapagos tortoise's shell (carapace) is black and its shape varies among the subspecies. The carapace of some subspecies is upturned just above the neck, enabling the tortoise to reach its neck up to grasp onto taller vegetation (Source: Burnie and Wilson 370).
