This long thin creature can puff itself up or shrink itself down. What is the name of this deep sea creature that can open its mouth so wide it can swallow creatures of its own size?

The gulper eel, otherwise known as the pelican eel, is able to open its mouth so far it can swallow prey of its own size. It is also able to puff itself up or shrink itself down. Gulper Eels can be found at depths of 1,640 feet to 1.83 miles (500 m to 3 km).
