Spinadraguanga spinagatorus
Evolved from S. spinaspinus larger members moved to zone 3 and zone F(nesting) in search for more Rostrovenator species to feed and sustain themselves. They evolved to be bigger as well to wrestler with more larger Rostrovenator species native to zone 3.
found in zone 3 and zone F they grow up to 6 feet long. Mostly found on the surface where they hunt and find prey that usually breach the surface to breathe. Once it finds a target they would propel itself fast enough then strikes down with its jaw on the neck while its claws slash the belly and wings to wound it from running. The prey would die from blood loss. The prey on P. natans, P. unculodon, R. gigas, R. letaligibbas, R. parvus, S. communis(occasionally) and R. rostrus. They would rather eat calves, subadults and juveniles of their large prey as it is easier to hunt them then the adults. They are seen mostly solitary in hunting but each territory would either have a mated pair or a solitary specimen. However some specimens have been seen in pairs working together to hunt adults Rostrovenator and Proplatecarpus as their prey usually both using their claws and jaws to bleed their prey to death. When on land in zone F they are seen defending their young from A. sarafacornis and D. aquacanthus easily out sizing and killing them with ease but would still pick on the young if there is an opportunity. They are usually only found in the shores of zone F or the jungles near the shore. Their humps are used as a swim bladder when swimming but deflates when they are on land.
When breeding mated pairs are usually bonded for life and newer males would try to impress females to get them pair to the male. When they are bond they will mate then lay their eggs(up to 4-8 eggs but only 2-3 survive due to predation from A. sarafacornis and D. aquacanthus) 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 nursing them (teach how to swim and hunt) while the other will be hunting to bring them food. When they are subadults they will chase them off to fend for themselves. If one of the mated pair dies the survived pair will mourn for a week before going back to its regular basis but extreme old bonds may lead to the survive pair to not eat or even drink and would not leave their dead mate corpse alone and morns it until it dies as well from starvation as if it wants to die with their mate.
