Cane Toads In Australia
June 1, 2013 by staff
Cane Toads In Australia, The cane toad (Bufo marinus) is an invasive species in Australia. The cane toad is the largest species in the family Bufonidae. Adult cane toads are usually heavy-built and weigh an average of up to 1.8 kg. (4 lbs.). Their size may vary from 15-23 cm.(4-9 in.) and their skin is warty. The coloration on their back and sides may vary from olive-brown or reddish-brown, gray, and yellow while their bellies are semi-yellow or semi-white with darker mottling. Their body is round and flat, has prominent corneal crests, and light middorsal stripes.
Their front feet are unwebbed, but their back feet have tough, leathery webbing. Cane toads have short legs and a ridged bony head that extends forward from their eyes to their nose. Behind their ears lie the parotid glands, which usually causes their head to appear swollen.
These glands are used for defense against predators. The parotid gland produces milky toxic secretion or poison that is dangerous to many species. This venom primarily affects the functioning of the heart. Envenomation is painful, but is usually not fatal for humans. However, it does have some effects, such as burning of the eyes and hands, and skin irritation.
