Info

[captive] Loosejaw fish (Malacosteus niger) with a light organ beneath its eye. The are also called black dragonfish (Malacosteus niger) and are a deep sea fish mainly preys on copepods. This species is among the small group of deep sea fishes that are able to emit red light and also to see it. This has only lately been revealed by scientists. The black dragonfish shines on its prey to see it without the prey even noticing that it is floodlighted – and without ringing the dinner bell for other predator species. [size of single organism: 6 cm]. Atlantic Ocean, close to Cape Verde | Schwarzer Drachenfisch (Malacosteus niger)
