Leviathan Class Organisms

Leviathan is a classification given to extremely large creatures. Although the wording of the Reaper Leviathan's data bank entry would seem to imply that the leviathan classification is exclusive to predatory life forms, this is not the case; any fauna species of a suitable size can be classified as a Leviathan. Leviathan is not part of a taxonomic classification so does not imply any of the species classified as such are related. In fact, the only two that appear to have any close relation are the Sea Emperor Leviathan and Sea Dragon Leviathan who share several features including an almost identical body shape, seven identically positioned tentacles, forelimbs and light producing organs protruding from their snouts. Despite being enormous when compared to the fauna of Earth, the leviathans inhabiting Planet 4546B in the present day are dwarfed by their predecessors; the three million year old Gargantuan Fossil at completion measured an estimated 6-8 times longer than a fully grown Sea Emperor specimen at 1200-1500 meters in length.
