Drone footage captured a pod of orcas, also known as killer whales, attacking and eating another whale, presumably a southern right whale, in the waters near the Valdes Peninsula in Argentina. The video is believed to be the second documented instance of orcas preying on a southern right whale calf. Experts say the footage demonstrates the hunting tactics of orcas, such as their method of surrounding the calf and the precision in their attacks. #nature #science #orca #killerwhale #argentina #mar
