According to Starfinder’s bleeding condition rules:
You take the listed amount of damage at the beginning of your turn each round until this condition ends. Your bleeding can be stopped with a successful DC 15 Medicine check as a standard action, or through the application of any ability that restores Hit Points.
Some aliens have innate capabilities that allow them to restore hit points and can stop the bleeding in this way. Other aliens have the Medicine skill (or an ally with the Medicine skill) and can thus stop the bleeding that way. But what about unintelligent monsters, or aliens that simply have no medical training? Are they doomed if they get the bleeding condition and don’t have some capable healer at hand to stop the bleeding?
