Kabutops, Known as the Shellfish Pokémon, is the evolved form of Kabuto. Kabutops is loosely based on trilobites as a counterpoint to Omanyte and Omastar representing ammonites. This can clearly be seen with the enlarged cephalon and the pygidium and thoracic spines. It was introduced in Pokémon Red and Blue, where the player-character plays a part in reviving the assumed-extinct species by giving a Fossil to the Scientist on Cinnabar Island. Kabuto's four insect-like legs have vanished and two long feet stand in their place. Two long sharp claws (or sickles) extend from Kabutops's exoskeleton and several plates close the opening that used to be there. There are six hard spikes going down from the back of its neck, three on each side that lead down towards the beginning of its tail. Its head is covered in a rock hard, semicircular shape armor. A tail protrudes from its back, bearing the same color as approximately seventy-five percent of its body. Its gills have also begun to change to make it land compatible. Kabutops lives in the water, and its sleek body enables it to swim faster by tucking in its limbs, folding up its claw-like sickles and wiggling. The creature comes out of the water to hunt. Kabutops is a predator, but its nature of feeding is vampiric; instead of killing its prey, it uses its razor sharp claws to open wounds in its prey, and then drink its blood. Adaptations in its body permit it to lead a more terrestrial lifestyle than its predecessors. It is also very adaptive as shown when its prey started living on land so Kabutops adapted to living on land as well.
