A video that was captioned “Why Orcas are the apex predators of the ocean” showed clips of the killer whales working together to get a meal by creating waves that will knock out seals taking cover on ice sheets.
The orcas would first peer to see a seal resting on an ice sheet, then they would swim in a group right underneath the ice sheet, thereby creating a wave that would destroy the ice or sweep off the seals.
