A giant eel can traverse water. It in amphibious. It is part of the large family of serpents. It has no limbs. A giant eel cannot pick up objects. It is able to lay eggs. It is a carnivore.

The behaviour of eels in fresh water extends the air of mystery surrounding them. They move freely into muddy, silty bottoms of lakes, lying buried in the daylight hours in summer. ... Eels are voracious carnivores, feeding mainly at night and consuming a wide variety of fishes and invertebrate creatures. Contrary to earlier thinking, eels seek living rather than dead creatures and are not habitual eaters of carrion.
