both male and female of this species are the same in coloration.

Irritator, with a name like that you'd expect this species to be annoying but the reason is that its skull was irritating to reconstruct. Which gave this small fish eater its name. The irritator is the smallest spinosaurid on the island and can be found around the islands many rivers. Although its diet is mostly fish it will snack on small animals when the opportunity is there. And with its dark coloration it appears rather intimidating, but the irritator is the most harmless of the islands spinosaurids. The weird shape of the jaw aids the animal when fishing, as it is built like a fish trap and lined with long piercing teeth used for stabbing the fish it catches. The animals bright blue head is used as a lure for the females during the mating season. And its long clawed fingers are used for slicing its fish meals. All these things make the irritator a very interesting dinosaur indeed.
