The '''Space Sharks''' [[Space Marine]] chapter are a Loyalist Chapter of Space Marines of the [[Second Founding ]] whose origin remains unknown and whose current homeworld is that of [[Mantis Warriors ]] former homeworld of [[Ootheca]]. There is some speculation that the '''Space Sharks''' may be a Successor Chapter of the [[White Scars]]. Part of the [[White Scars]] Legion's Scouting Company was separated from the rest of the Legion during the [[Horus Heresy]]. Upon returning after the end of the [[Horus Heresy]] they formed their own [[Space Marine]] Chapter specializing in the use of Scout Marines.⁶
