Horned Brimshell Pedipeworm
A small change can be observed between this creature and its ancestor, the brimshell flatworm. In this form, the animal developed five small pairs of legs with which it can walk on firm land, but it generally is placed close to the water, which it still depends on to absorb its food. Its old shell was flattened and small thorns had appeared, allowing the creature, with a very slow locomotion, to defend itself from some predators. When eating them, the predators feel an awkward sensation proportionate to the thorns and, generally, they liberate the pedipeworms. Its horns had been prolongated and also developed a primitive system of perception, located on small points on the long horns. With these sensors, they are capable to interpret environmental variants as smells, allowing them to orient themselves. This is a very important sense, since these creatures have no eyes.
