Cane Toads and the Rain

The heavy rains we are experiencing is bringing Cane Toads out into the open,fortunately they are not so prominent as in other parts of Queensland,however,we did have a visitor last night and Ann quickly gave it a dose of Dettol which provides almost instant death and these creatures are a danger to animals in particular dogs.Humans can also be infected by them.Strangely they are not to be found anywhere when the weather is hot and it is difficult to understand how they appear so quickly with rain !! When on our travels in Kuramba on the Gulf of Carpenteria Frog skins were made into handbags,purses etc and I have NO idea who would buy them

The cane toad (Rhinella marina) formerly 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

Currently, most attempts to curtail the invasion of cane toads have been unsuccessful. Many of these strategies involve the physical trapping of toads, but these methods also capture unintended native species.Since the largest selective pressure on cane toads currently is intraspecies competition, these physical removals often only improve the conditions for untrapped toads. Also, since migration is high, any area purged of toads would most likely be reinvaded quickly.Many new ideas have been proposed to control the cane toad population. Some have suggested introducing a native viral or bacterial pest of the toads, but this has potential to once again invade native species. Two similar strategies have been proposed, both of which focus on fecundity. One involves the release of sterile males into the population. These males would compete for resources with other males, while themselves not being able to reproduce. A second strategy would be to insert a gene in female toads which would allow them to only create male offspring. In theory, this would limit the reproductive rates and control the population. It is difficult to determine the efficacy and dangers of these approaches, as these methods have never been attempted, especially on a large scale.On 13 June 2012 news reports cited a new research breakthrough regarding cane toad control. Research has confirmed that cane toad tadpoles are attracted to the toxin produced by adults and spawn. Tadpoles are believed to cannibalize toad spawn as a food source. Researchers used cane toad toxin to successfully lure cane toad tadpoles, implying that in controlled areas tadpoles could be captured and eradicated.The RSPCA has guidelinesfor the humane culling of cane toads. Inhumane ways include spraying with DettolPhenyl and using golf clubs, but these are illegal in most states and territories .[citation needed] Due to concerns over potential harm to other Australian wildlife species, the use of Dettol as pest control was banned in Western Australia by the Department of Environment and Conservation in 2011.
