In a new study, researchers offer a novel explanation for why a type of Antarctic killer whale performs a rapid migration to warmer tropical waters. One tagged Antarctic killer whale monitored by satellite traveled over 5,000 miles to visit the warm waters off southern Brazil before returning immediately to Antarctica just 42 days later. This was the first long distance migration ever reported for killer whales.
