This centenarian Casanova has fathered approximately 40% of his subspecies.
Few have contributed to their species in the way Diego, a 100-year-old Galapagos tortoise has. After scientists studied members of his subspecies on the island of Española, his native home, they learned that the centenarian Casanova is responsible for fathering approximately 40% of all Chelonoidis hoodensis in the area.
Due to tourism and overexploitation of the island, populations of the tortoise dropped between 100,000 and 200,000 during the 19th century. Fortunately, Diego was blessed with a healthy libido and did his part to help perk up populations of his subspecies.
According to IFLScience, Diego has fathered approximately 800 offspring in his lifetime. Washington Tapia, a tortoise preservation specialist at Galapagos National Park, commented on Diego’s insatiable sexual appetite.
“He’s a very sexually active male reproducer. He’s contributed enormously to repopulating the island.”
Considering a Galagos Island turtle can live up to 190 years, it doesn’t seem likely that Diego is done fathering offspring. That’s a positive thing, because according to AFP news agency, populations of the Chelonoidis hoodensis are not back to their former health. At present, there are about 2,000 tortoises on the island of Española. On all islands, there are about 20,000 wild tortoises, made up of between 12 to 14 different subspecies and separate populations.
