Orca

Fascinating facts about the Orca

• Each orca's dorsal fin and saddle patch act like a fingerprint; unique nicks, scratches, and colour patterns let scientists identify individuals. This visual ID system lets researchers count exact numbers each year, turning vague population guesses into precise data that guide conservation actions.
• Off the west coast of North America, resident pods hunt fish while transient pods hunt marine mammals, a split that mirrors distinct cultural traditions passed down through generations. These dietary specializations show how learned behavior can create separate ecological roles within a single species.
• In late 2005 the southern resident orcas were added to the U.S. Endangered Species list, a stark reminder that even apex predators suffer when prey disappears, habitats degrade, or pollutants like PCBs accumulate, threatening the survival of whole family groups.
• A single male orca can reach 10 m (33 ft) and weigh over 10 t, making it the largest dolphin and giving it the power to tackle prey as big as other whales, shaping marine food webs from the top down.
• Orcas can grow to extraordinary lengths, with the biggest males measured at 10 m (33 ft). They are the largest members of the dolphin family and are apex predators.
