Short-range attack hunters, poison-tipped beach quills often strike in colonies. Individually among the smallest animals on Darwin IV, in packs they can fell even the largest animals on the planet. Each beach quill can propel itself with enormous velocity over short distances by means of a folded, muscular "foot" that snaps the animal through the concealing undergrowth toward its target. Beach quills stab into their prey, each of the animal's quills delivering a dose of neurotoxin.
