Marine Animal Facts To Keep You Awake

Marine animals are full of fascinating quirks. Did you know that some species, like dolphins and whales, never truly fall asleep? Instead, they rest one half of their brain at a time while the other stays awake to keep them swimming and breathing. Octopuses are masters of camouflage, capable of changing both their color and texture to blend seamlessly with their surroundings. Sharks have a super sense called electroreception, allowing them to detect electrical signals given off by other animals, even those hidden in the sand. Sea turtles can navigate thousands of miles across the ocean and return to the same beach where they hatched using Earth's magnetic field as a guide.
