Remora fish, known commonly as suckerfish, are technically not parasites. They’re just along for the ride. You’ll often see them stuck onto a large marine animal like a shark or a whale and sometimes even small boats, getting free transportation across miles of the ocean while spending very little energy. |

These odd creatures have flat foreheads that look like the bottom of a shoe. But it’s this strange suction-cup forehead that allows remora fish to cling onto dolphins even as they twirl into the air and slam back down into the water. |
