Bubblerorm

The bubblerorm replaced their ancestor, the blurorm. Their most striking adaptations that of their reproductive organs. They now produce about twenty microscopic buds, which grow in the bubble sac in front of their body. They nurse these with digested particles for a few days, then release them into the sand where they mature then rupture in about two days. They now also have a more advanced nervous system, with a network of nerves running along their bodies, centering in two nerve clusters and the bases of the hair like appendages.
