The sandtrap replaced its ancestor the stumpworm sucker on Krakow Beach. It now has a semi-subterranean lifestyles where it will gig itself into the sand without its eyes peaking out. When a scuttlecrab or bubblehorn walks by it will have it long tail spring out from under the sand and grab it with its talons. Once pinned it will inject its prey with acidic fluid from its hollow tooth. This fluid digests the prey on the inside, and it sucks the goo out with its hollow tooth, much like a spider.
