The lanced ketter has quickly developed from the ketter and has almost completely replaced it. The lanced ketter holds a few advantages over its predecessor. Its ears have enlarged, increasing its hearing range, and the smelling organs behind its eyes have refined themselves; it is now capable of smelling a mate or an intruding predator from a little over a kilometer away. The most notable difference is the lance-like appendage on the ketter's head which is used to skewer worms, most notably winged worms. The ketter will spot a winged worm and perch itself on the edge of a bubble tree branch or gyroleffo and leap straight at its prey with pin-point accuracy to skewer its prey on its head. The leaf on the lanced ketter's back can be pulled out slightly with its back muscles to aid in a more controlled fall, although it doesn't actually glide. Lanced ketters live in family packs of up to 30 members.
