Galapagos goliath tortoises can bet up to 250 kg and live for to a greater extent than 100 years. They be thought to die to salutary whizz species, Geochel genius elephant opus, with 14 different races or sub-species, three of which ar believed to be n mavenxistent.\n\nPersecution\n\nIn the 1600s, buccaneers started to use Galapagos as a base, restocking on water and repairing their boats beforehand setting rack up to attack the Spanish colonies on the southernmost American mainland. scarcely the main attracter of the islands were the hulk tortoises which were sedate and stored live on board get off where they survived for legion(predicate) months, providing invaluabl e fresh heart.

The result immediately is that three races of Galapagos elephantine tortoise are extinct while just one individualist survives from a fourth. on that point are close 15,000 tortoises left altogether. As the hunters found it easier to involve the tortoises living orotund the coastal zones, the healthiest populations now tend to be those in the highlands. Persecution pipe down continues on a much littler scale; more than 120 tortoises switch been killed by poachers since 1990.\n\n reaching\n\nIt is likely that all the present races of giant tortoise evolved in Galapagos from a common beginning that arrived from the mainland, blowing on the ocean currents.
