The tube rocket is a deuterostome radially symmetrical organism distantly related to the rock worm. It swims through the water by passing water through its muscular gut, It was the fastest creature seen in the early xenocambrian era. It would catch prey simply be swimming up to them and sucking them into itself with the unfortunate side effect of it not being able to swim while digesting a large meal making it vulnerable to attack. As it grows one of its five sides starts to dominate the others and would have a substantial amount more neuron density than its other sides.
