Swordfish may be using deep dives to navigate the open ocean
Swordfish regularly hunt at great depths but occasionally dive even deeper, with some reaching over 1,000 meters below the surface. Scientists from Woods Hole Oceanographic Institution are studying why swordfish make such deep dives. These extreme dives occur in addition to their usual hunting activities.
Why it's good news: It shows that swordfish are capable of navigating and adapting to challenging underwater environments.
