A remora is a type of fish known for its unique ability to attach itself to larger marine animals, such as sharks and turtles, using a specialized suction disc on its head. This adaptation allows remoras to travel long distances while benefiting from the protection and food scraps provided by their hosts. Remoras are typically small, ranging from 15 to 30 inches in length. They are often found in warm ocean waters and are known for their gray or brown coloration, which helps them blend in with their surroundings. This symbiotic relationship is beneficial for both the remora and its host.
