Pinzon harbours its own endemic species of Galapagos tortoise (Geochelone ephippium). It has a saddled back carapace which enables long neck extension. Their main food includes grasses, cacti, lichen, moss and leaf litter.

Numbers dwindled to about 200 in the mid 1960's and it appeared that the population was not increasing because all hatchlings were being eaten by introduced rats.

Numbers have increased by about 50% thanks to the rearing programme which has been rearing giant tortoises on Santa Cruz and transferring them to Pinzon once they are larger: at a 'rat proof' age. See Conservation Issues for further details.

Whilst Pinzon is of limits for land based visitors, we can dive here, most often on day trips from Sta Cruz. This is a dive site suitable for beginners and intermediate divers.  We usually dive on the east side where two tower-shaped rocks emerge. A wall covered in black coral drops to 10 meters and from there is a sandy slope that drops to more than 50 meters. Species commonly observed include the red lipped bat fish, sea horses, sting rays, turtles and white tip reef sharks.

The island is also home to a number of sea lions, the pups of which make for playful diving companions.
