However, the devastation of great whale populations by unfettered whaling has possibly reduced their availability for killer whales, and caused them to expand their consumption of smaller marine mammals, thus contributing to the decline of these as well. Another conservation concern was made public in September 2008 when the Canadian government decided it was not necessary to enforce further protections (including the Species at Risk Act in place to protect endangered animals along their habitats) for killer whales aside from the laws already in place. [34][117][118][119] Predation by orcas on whale calves in high-productivity, high-latitude areas may account for great whale migrations during breeding season to low-productivity tropical waters where orcas are scarcer.

Wood cut engraved illustration, taken from 'The Treasury of Natural History' by Samuel Maunder, published 1848. This pattern is consistent with Ridgway and Brownson , who found a positive relationship between surface area and brain weight among odontocetes, including the killer whale, bottlenose dolphin, and common dolphin.
