Long-spine Porcupinefish Mating | Diodon holocanthus | Lembeh Strait, Indonesia

Male long-spine porcupinefish (Diodon holocanthus) pursuing a female fish. This was the culmination of several hours of activity involving a number of males pursuing this female, until finally only one male was left. During the pursuit, the female swam at rapid speed in seemingly random directions, as if she were trying to lose the males. She hid in crevices at times, forcing the males to search for her. The males nipped and bit her constantly. The actual mating event took place well after sundown, with the fish swimming out to a deep part of the channel at about 23 meters, then rushing toward the surface, releasing eggs and sperm at about 12 meters depth.
