The killer whale is a very social animal and they hunt together in packs called pods. They work together to kill seals and even larger prey like whales. The largest killer whale found was 9,8 m (32 ft) in length and weighed 10,000 kg (22,000 lb). As killer whales grow their heads become shorter as they age. The females breed up to age 40, meaning on average they might raise 5 offspring during their life. The lifespans of wild whales average around 50 years with a maximum age of 80 to 90. The oldest known killer whale was a female named granny. She was estimated to be 103 years old.
