The ocean is home to a variety of fascinating creatures, some of which have surprising features and abilities. In this article, we will explore three of them: dolphins, octopuses, and taraba crabs. You may think you know these animals well, but there are some facts that might surprise you.
Dolphins Shed Their Skin Every Two Hours
Dolphins are known for their intelligence, social behavior, and echolocation skills. But did you know that they also have a very fast skin turnover rate? According to Scientific American1, dolphins shed their outer layer of skin every two hours, which is nine times faster than humans. This helps them maintain a smooth and streamlined body surface, which reduces drag and increases swimming efficiency. It also prevents parasites and infections from attaching to their skin. Dolphins may also rub their bodies on corals and sponges to remove dead skin cells and stimulate new growth.
Octopuses Have Nine Brains
Octopuses are among the most intelligent invertebrates, capable of solving problems, using tools, and changing their appearance. But did you know that they also have nine brains? According to Biomechanics in the Wild2, octopuses have one central brain in their head and eight smaller brains in each of their arms. This allows them to control their arms independently and process sensory information from their suckers. Each arm can taste, touch, and move without input from the central brain. The central brain, however, is responsible for deciding what the octopus wants or needs, such as searching for food or escaping from predators.
Taraba Crabs Are Delicious But Related to Hermit Crabs
Taraba crabs are a delicacy in Japan, known for their large size, long legs, and rich flavor. They are often referred to as the king of crabs and are enjoyed as a luxurious food. But did you know that they are not actually true crabs? According to Japanese Products Blog3, taraba crabs are closer to hermit crabs than to crabs in biological taxonomy. They belong to the infraorder Anomura, which includes hermit crabs and other crab-like crustaceans. Unlike true crabs, which have ten legs, taraba crabs have only eight visible legs. They also have the ability to walk lengthwise, unlike most crabs that can only walk sideways.
We hope you enjoyed learning about these amazing marine animals. Next time you see them in the ocean or on your plate, remember that there is more to them than meets the eye.
