A Comet Eater is one of many interstellar creatures (known as Leviathans) whose primary habitat is outer space. Like all space born wildlife, the comet eater grows to a massive size needing to consume matter in vast quantities to supplement internal biological reactors. Most leviathans tend to eat space craft for the exotic alloys in their hulls, the rich isotopes in their reactors and rare protein piloting them. Eaters are given their name sake preferring to consume icy as comets, basking in the long tails. Unlike most, the Comet Eater tend to stay in the comet cloud/belt outside solar systems. It lacks some of the more impressive propulsion systems of other space born creatures. Growing to an average size of 725km, they can collapse into system gravity wells and plunge into suns.
