"Unraveling the Enigma of Shark-Bitten Orcas in Deep-Sea Canyons"

A new study suggests that a group of killer whales spotted off the coast of California and Oregon over two decades may represent a previously uncategorized population of orcas. These orcas exhibit unique behavior and ecology, including deep-sea habitat preferences and distinctive scarring from encounters with cookiecutter sharks. The study's findings shed light on the presence of a distinct oceanic population of killer whales and highlight the importance of further research and observation to understand their behavior and ecological significance.

"Glow-in-the-dark predators: The mysterious cookiecutter sharks attacking boats"

A boat attempting a round-the-world voyage was attacked by cookiecutter sharks, a type of shark known for its vampiric teeth that can take 2-inch round chunks out of much larger prey. These sharks, which are bioluminescent and grow up to 20 inches long, usually feed in deep waters during the day and near the surface at night. They have been known to damage undersea cables and sonar components of nuclear submarines. While they are not typically man-eaters, their attacks can be extremely painful as they travel and dine in schools.
