Happy Father’s Day from the Gold-specs jawfish (Opistognathus randalli)! Dads-to-be of many jawfish species carry eggs in their mouths. This behavior helps protect offspring from predators. To attract females, male jawfish do a “dance” that involves a series of sweeping movements and fin-flashing. And the crescendo of this courtship ritual? Males open their mouths as wide as possible to boast their mouthbrooding potential!
