What is so unique about the sunfish?

The sunfish, or mola mola, is unique for its distinctive shape, resembling a giant pancake with a flattened body and a large dorsal fin. It is one of the heaviest bony fish, weighing up to 2,200 pounds, and can reach lengths of over 10 feet. Sunfish are known for their behavior of basking in the sun at the ocean's surface, which helps to regulate their body temperature and shed parasites. Their unusual swimming style, often seen "on their sides," further adds to their fascinating characteristics.
