These exsurgents look like four-armed starfish, capable of walking like quadrupeds on their spiny limbs. Each appendage ends in thin, clawed digits useful for climbing and tool use. The arms also house sensory bands for hearing and infrared vision. The underside of the creature houses a circular mouth ringed with hooked teeth. This mouth can distend outwards like a leech, enveloping much larger prey than it might seem. Wrappers are ideally suited for microgravity habitats due to a series of vent sacs capable of significant thrust.
