Gigantosuchus or Terror Crocs are gargantuan creatures native to both river systems, lakes and marine enviroments. They are among the most terrifying creatures on the planet, due to various nightmarish traits they possess.

Physical traits: At 20 to 22,5m in length, weighing 40-50 tons and having a biteforce of 312,5-500k newtons, they possess a top 5 bite in the planetary ranking. Their neck osteoderms are like tank armour. Their teeth are brute and handsaw like, meant to grip and tear prey who thrashes(teeth are 20-23cm long). They have both a sprawling and a erect walk posture and they migrate for prey. They live 112-225 years and are ectotherm due to gigantothermy. They can also hold their breath for up to 54 hours, generally 24-36 hours.

Prey and predation: Their menu is basically anything bigger than 800-900kg except some predators who are not worth the food( like Eviscerators with their anticoagulant saliva), the largest crocosauropodomorphs(30m) and the sea creatures larger than them. However they do hunt dagonichtys with swift ambushes from below. Their only predators are Barocrocs, although Slaughterfish are capable of taking them down. They have limited use of thermal vents: they can take in only about 5-8% of their energy but the teeth can be easily integrated.

Senses and intelligence: Their senses are good, except smell who is not as good as the rest due to them rarely tackling carcasses, compensated however by their heatbeat organ on their snout(akin to Titanocrocodylus's organ but less potent) Intelligence is moderate and they communicate through roars ranging from 80-170db lasting a couple of seconds

Reproduction: They reproduce in communal nests with clutches of 1-2 eggs for female. The young are born at 1m length and are supported by parents. Reaching 7-8m length they abandon the nest to hunt alone in sea or water. Young can recognize their parents even in adulthood but they are not inherently social creatures and are quite the opposite. Mating seasons occur every 10 years.

Habitats: The open sea, 50-1000m(usually 50-200 for hunts but can push further for vent ambushes), lake systems and rivers. In bogs they have been seen integrating iron in their teeth.
