The geologist J. Bret Bennington noted in 1996 that though Dilophosaurus probably did not have a frill and could not spit venom like in the movie, its bite could have been venomous, as has been claimed for the Komodo dragon. He found that adding venom to the dinosaur was no less allowable than giving a color to its skin, which is also unknown.
It uses its venom primarily as a means of defense. The spitting cobra has the ability to direct venom up to three metres away from its location. [1] The trajectory of the venom that the cobra sprays is not at random. The spitting cobra has evolved to aim the venom that it spits into or as close as possible to the antagonist’s face and eyes.

The spitting spiders Scytodes can spit a venomous sticky fluid that traps its victims and also poisons them. [1] The bombardier beetle is unusual by using a violent exothermic chemical reaction to launch a boiling noxious chemical spray in a rapid burst of pulses from special glands in its abdomen, accompanied with a popping sound.
Dilophosaurus was one of the earliest large predatory dinosaurs, living in what is now North America during the Early Jurassic, about 193 million years ago. The genus name means "two-crested lizard". It was smaller than some later theropods, about 7 meters (23 ft) in length, with a weight of about 400 kilograms (880 lb). It had a pair of plate ...

Platypus venom is entirely different from other venomous creatures. While more research is needed, scientists believe it contains specific proteins that target the nervous system. Heptapeptide 1 ...
Toxungens have evolved in a variety of animals, including flatworms, [4] insects, [5] [6] arachnids, [7] cephalopods, [8] amphibians, [9] and reptiles. [10]Toxungen use possibly also exists in birds, as a number of species deploy defensive secretions from their stomachs, uropygial glands, or cloacas, and some anoint themselves with heterogenously acquired chemicals from millipedes ...
Jellyfish sting using microscopic cells called nematocysts, which are capsules full of venom expelled through a microscopic lance. Contact with a jellyfish tentacle can trigger millions of nematocysts to pierce the skin and inject venom.
