There are two found on the upper levels of Lost Izalith and six more (four don't respawn) located through a destructible floor, in a pit close to Siegmeyer of Catarina. A total of four chaos eaters can be farmed each pass.
Chaos Eaters are large, multi-eyed, multi-legged demons that are able to grab and throw their opponent into their gigantic mouths, located on top of their heads, swallowing and excreting them through one of their "legs". They can also spray a corrosive white mist, through said legs, quickly damaging the player's equipment.
Despite having multiple eyes, it is still possible to sneak up behind them.
