Opabinia

Opabinia, another small Cambrian critter, grew to eight centimeters (about three inches). This creature likely caught prey with the grasping claws of its long, tube-like proboscis and then stuffed the food into its mouth — much as an elephant uses its trunk. Opabinia may have even used its proboscis to pull worms out of their burrows.
