In captivity, breeders are inseminating Killer Whales much younger than they would naturally breed in the wild, resulting in very high miscarriage and stillbirth rates as well as increased mother and calf mortality rates. At some time after birth, it is a common practice to separate the mother and calf. However, in the wild Killer Whales live in family pods for their entire lifetime. This separation is traumatic for both the mother and the calf.
