Henry the tuatara is finally becoming a father. It took him a bit longer than you might expect at 111 years.

Henry has been kept in captivity for the last 38 years, during which time he showed very little interest in mating with some ready females. All that changed after Henry had a cancerous growth removed.

Suddenly Henry became horny for one of the three females that stayed with him at the Southland Museum on New Zealand's South Island. Mildred must have really caught his fancy because that's who he ended up impregnating. Mildred was able to lay a dozen eggs, even using Henry's centurion sperm.

Henry may even breed again. Henry's attitude has improved quite a bit over the years. For one 17 year stretch Henry was in solitary confinement because he was too aggressive towards his fellow tuatara.
