Lifespan, longevity, and ageing
Maximum longevity: 35.8 years (captivity) Observations: The mata mata turtle is one the most bizarre-looking and, some would argue, ugly animals on the planet. Little is known about its lifespan in the wild. In captivity, specimens have been known to live over 30 years (http://www.pondturtle.com/). There are anecdotal reports of animals kept as pets living over 35 years, which is plausible. Also spelled "matamata".
