i know dilophosaurus was referred to as poisonous in both the novel and the film, but it is actually venomous. the distinction between a poisonous animal and a venomous animal lies in how it delivers its toxin. a venomous animal, such as a snake or a spider, delivers its toxin via a bite or a sting. a poisonous animal, such as a frog or a caterpillar, delivers its toxin via secretion or ingestion. in other words, venomous animals have an apparatus for delivering the toxin, while poisonous animals do not. coming to my point, i was disappointed to hear harding, the park veterinarian, refer to dilophosaurus as "poisonous" in the new ign footage.
