Jenny, the world’s oldest gorilla in captivity died at the age of 55 in the Dallas zoo. She suffered from an inoperable stomach tumor. This is the second gorilla the zoo has lost this year. Hercules, a 43-year-old silverback died of a heart attack recently. The zoo is keeping an eye on the four remainining gorillas to make sure they don’t slip into a depression. The scary thing is that one of the four gorillas is 46-years-old.
BTW – The lifespan of a gorilla in the wild is about 35 years.
