Power's Deepwater Bristlemouth (Vinciguerria poweriae)
Bildnummer 13357628
| Power's Deepwater Bristlemouth (Vinciguerria poweriae) is a Lightfish from the family Phosichthyidae. These mesopelagic fishes are part of the deep scattering layer a group of species that move from deeper mesopelagic waters at night, toward the surface, to feed in the productive epipelagic. At dawn, they go back to deeper waters. This is the largest migration of animals on Earth and it happens every day. The light producing organs on this fish (photophores) accomplish at least two items: (1) they produce a dim blue light that matches the light intensity from the surface and help to eliminate the silhouette of the fish from predators looking upward (counterillumination). (2) Undoubtedly, the photophores also help identify the individual to conspecifics in the darker waters of the mesopelagic. This individual was photographed in the Gulf of Mexico and trawled at night from between 200 meters depth and the surface (656' depth and the surface). Image courtesy of the DEEPEND project. | |
