Spikedshell Bubblehorn

When the Horned Brimshell Pedipeworm acquired independence from the aquatic environment, it needed to develop a stronger shell to protect itself from predators. Its old shell was inflated and developed a big number of thorns. The olfactory sensors in its horns had evolved antennae with globular extremities, with which the creature better perceives odors. Its feeding, which had before occurred in the presence of water due to the need of dissolved foods, started to occur on land, where the creature started to acquire coprophagic habits, feeding on the fresh excrement of the terrestrial creatures. For this it also uses its olfactory sensors, which touch the excrement and take it into the mouth of the Bubblehorn. This creature has an important role in the ecosystem of Sagan 4, eliminating part of the waste of other terrestrial creatures which before had remained abandoned, and it also brought, during its move onto land, some adhered microscopical creatures within its body, whom had also contributed to the elimination of waste. This insertion of new creatures into the ground promoted the release of a great amount of organic substance, fertilizing the ground and promoting the appearance of new forms of life, in special plants.
