Evolutions/Adaptations: Added a second brain; increased neuron density, increased synapse connections that each neuron can create, the exoskeleton is harder, the sensory stalks fully ritired inside the body making 2 cavities(sensory cavities), the electroreceptors organs have an higher concentration of electroreceptors.
Other Changes: It’s brains are better able to recognise patterns wich help them evitate the thalasicaphantom, it also puts it’s brains to sleep alternativelly, when one brain is sleeping the other is awake.
Evolutions/Adaptations: added muscles around the gills that make them able to do active respiration; the upper mandibles are retractable, it has an higher concentration of photoreceptors in the eyes, it now does internal fertilization, the legs are longer, it has more segments.
Other Changes: the number of segments have increased to 5 segments, the longer legs make it able to run faster, it can out run the other land dwelling species, and it’s exoskeleton is too hard for other predators to damage, it truly is the apex predator of the land.
Evolutions/Adaptations: has muscles around the gills that make it able to do active respiration; has more segments, the upper mandibles are shorter, is tinier, the lower mandibles have stronger muscles, the males exoskeleton is reddish.
Other Changes: it became herbivore, and it uses the lower mandibles to rip off parts of plants and bring them to the mouth, and the upper mandibles are instead used for defence. It’s segments increased to 10, each segment is 4 cm long, it also is 7 cm tall, the males reddish exoskeleton is used to attract mates. After a female has been fertilized she will dig under the sand and lay her eggs into the hole and then cover it with sand.
Evolutions/Adaptations: has an organ that produces chemicals to break down food; higher concentration of chemoreceptors in the sensory stalks, has a slower metabolism, it is hermaphrodite, has a thicker exoskeleton.
Other Changes: it lives on the sea floor waiting for corpses of bigger animals that fall. Once it finds a corpse it will remain near it forming a temporary comunity until there is nothing left to eat from that corpse, it’s slow metabolism make it able to stay a long time without eating.
