Orcas May Specialize In Eating Sharks
While many dolphin species are smaller and less powerful than sharks, there is one dolphin that can make even the biggest sharks look like juveniles. They are orcas, also known as killer whales, and they are the largest member of the dolphin family. Average male orcas range from 20 to 26 feet long and weigh around 6 tons. Even the largest great white shark on record, at 21 feet long, would find itself at a size disadvantage against your average orca.
But do orcas use their size advantage to target sharks? Evidence suggests that may be true. In the waters off the coast of Costa Rica, orcas have been seen working together to take down a shark. It seems they are able to induce tonic immobility in a shark by turning it upside down, and rendering it still. In 2014, a video went viral in which a group of killer whales expertly teamed up to kill and eat a tiger shark.
These killer whales seem to erase all the advantages other predators usually have over dolphins, and they don’t take that for granted. In addition to sharks, they have been known to eat larger whales, walruses, seals, and sometimes even moose and deer that have gone for a swim.
