Starsharks are a species only portrayed in the Nintendo Comics System, and inhabited the asteroid field around RX 338. These creatures possess an incredibly powerful bite and are able to exist in an environment without atmosphere, something only few other known creatures (such as Ridley, Dark Samus, Leviathans, and Phazon Metroids) are known to be capable of. These creatures likely derive their name from the pentagonal arrangement of their pectoral fins, in addition to their previously mentioned habitat of a planetary asteroid field.
"Even worse, the asteroid field around RX 338 is infested with deadly Starsharks! These creatures feed on anything, from starship hulls to living flesh!"
