FAQ

• Saccopharyngiformes is an order of unusual ray-finned fish superficially similar to eels, but with many internal differences. Most of the fish in this order are deep-sea types known from only a handful of specimens such as the Umbrella Mouth Gulper Eel. 
• Saccopharyngiformes are also bioluminescent in several species. Some, such as the swallowers, can live as deep as 10,000 feet (3,000 m) in the ocean, well into the aphotic zone.
• Saccopharyngiforms lack several bones, such as the symplectic bone, the bones of the opercle, and ribs. They also have no scales, pelvic fins, or swim bladder. 
• The jaws are quite large, and several types are notable for being able to consume fish larger than themselves. Their myomeres (muscle segments) are V-shaped instead of W-shaped like in all other fish, and their lateral line has no pores, instead it is modified to groups of elevated tubules.
• DIET: The gulper eel eats fish, copepods, shrimp, and plankton. It uses its mouth like a net by opening its large mouth and swimming at its prey. Due to the gulper eel's specialised body shape, it is a poor swimmer and relies on the luminescent organ at the tip of its tail to attract prey.
