Gulper Eel Facts
The gulper eel is a weird-looking, eel-like fish, which is mostly found in the deep seas. Here is a brief overview about this eel, that is otherwise known as pelican eel or umbrella-mouthed gulper eel.
- They have big mouths that are wide enough to swallow large prey. In fact, the length of the jaws is almost one-fourth of their body length.
- Even the stomach of the gulper eel is stretchable, and can hold large amount of food. However, this fish feeds on small crustaceans, in spite of having a big mouth and a stretchable stomach.
- Even though, gulper eels have big mouths, their teeth are small; and this indicates that they are not intended to prey upon large animals. Apart from crustaceans, gulper eel diet includes fish, seaweed, cephalopods such as squids and octopus, etc.
- The mouth of the fish acts like a net, as it swims into large groups of small fish and shrimp. Their wide open mouth fills with food as well as water. The water is slowly released through the gill slits.
- Even the eyes of this deep-sea creature are too small. Expert opinion is that their eyes are meant for detection of lights rather than formation of images.
- This fish has a tiny light-producing organ at the tip of its tail. This organ called photophore, has numerous tentacles, and glows pink, through bioluminescence.
- This light-producing organ can also produce red flashes, occasionally. These red flashes are used to attract prey, as they keep their tail tip near their wide open mouths; so that they can swallow fish and other organisms that move towards the light source.
- It is said that mature males have bigger eyes and olfactory organs; as compared to females, who do not change much, as they become sexually mature. It is with the help of these olfactory organs that males sense the pheromones released by the females. It is also said that after reproduction, gulper eels die.
