Weed Eels are a specific variety of venomous eels which have excellent natural camouflage; indeed, a group of weed eels looks very much like a bunch of seaweed due to their “shaggy” scales and coloration. An individual weed eel is around 5 feet long and weighs about 300 pounds. Colonies of weed eels live in chaotic networks of tunnels with multiple “holes” or entrances arranged in clusters, and by extending themselves from these holes they complete the illusion of being just a patch of weeds.
