Spinecrawler

Evolved from S. spinagatorus in Zone H that moved into zone 6 while hunting. They developed to hunt smaller species. They developed vibration sensitive mechanoreceptors on their head are localized on either side of the head helping S. piscespinus to better detect its prey.

Found in zones H and 6, they grow up to 6 feet long. They feed on S. kelpalantus, R. unguladontus, R. pelagicoptera, G. makarealri, C. populator, T. therophagus, T. pelagicus, R. parvus, juvenile R. vagarium, and F. clamus. They hunt in open waters to Racomitrium forests, using their long broad tail to swim. They hunt by moving slowly then quickly dart at prey using its long jaws to grab the prey. Their air sac hump allows them to swim in the water better by helping them float.

Their mechanoreceptors allow them to hear vibrations underwater to hunt and avoid being predation. Their coloration is a dark green back with a grey underside. The males have a brighter green color. This coloration allows them to camouflage in the vegetation of zone 6.

Pairs usually mate for life and newer males would try to impress females to get them to pair. When they are paired they will mate then lay 4-8 eggs on a nest they dug. If the nest is going to be flooded they will relocate nest. Once the eggs hatch the mate pair would brood their young and take turns teaching them how to swim and hunt, while the other will be hunting to bring them food. When they are subadults the parents chase them off to fend for themselves. If one of the mated pair dies the survivor will mourn for a week before going back to its regular basis but extremely old bonds may lead to the survivor to not eat or drink and would not leave their dead mate's corpse alone and mourns it until it dies as well from starvation.
