I would use and argy to carry back to base and tamr in a pen. Start with darts because of low health then prime feed them. Get a higher lvl because oxygen lvl are much higher and then you can put the points into health and damage
They are skittish but not anywhere near faster than humans. They have low torpor and health, so tranq darts are recommended. Tamed like any carnivore, kibble is Archeopteryx. Can be found anywhere in and around the swamps.
