Both fish are also generally darker in colour than these specimens. One problem with bringing up fish from the deep is the damage that they have to endure from the trawls. In this picture, you can see the photophore behind the eye as a silvery circle. This placement is generally thought to help vision, and possibly to attract mates. Dragonfish are found at depths of 30m to 600m.
Snipe eels are another pretty crazy looking fish.
When they reach their full length of up to 1.2m, they resemble a long piece of ribbon or string with a bulbous little head on the end. A curious thing about this fish is that their upper and lower jaws curve away from each other at the tips. The reason for this is that when they hunt their favorite prey, shrimp, the antennae can slip between the fish's jaws and are caught by the back-facing teeth of the eel. The meal is then worked inwards towards the mouth, and eaten. Siphonophores are colonies of animals related to jellyfish, each one of which is specialized to fulfill a particular function.
