Vortex Snakes are relatively harmless enemies which will only hurt you if you bump into them. They are long, brown, and composed of segments, like a train's cars. All can be killed with a dual charge attack. A large stinger grows from the rear of their bodies, most likely a defensive appendage or peharps used to burrow into the ocean floor. Appearing prominently in the Lunar Bay and Dark Sea levels, they seem to have either evovlved from the surrounding fauna in the Dark Vortex Future or are a species direct from Planet Vortex.
When they die, they dissappear in a puff of foam, with a hissing sound.
In New Machine, a species will actively pursue Ecco through the room near the end of the level.
