The most notable case of cane toad consumption by birds involves the scavenging of dead ‘road-kill’ toads by raptors including the black kite and the whistling kite. [17] These birds have learned to eat only the tongue of the toad, leaving the rest of the carcass behind. [17] In this way, the raptors minimise the quantity of toxins ingested.
A young cane toad. The cane toad in Australia is regarded as an exemplary case of an invasive species.Australia's relative isolation prior to European colonisation and the Industrial Revolution, both of which dramatically increased traffic and import of novel species, allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the ...
The toad is able to rapidly acclimate to the cold using physiological plasticity, though there is also evidence that more northerly populations of cane toads in the United States are better cold-adapted than more southerly populations. [46] These adaptations have allowed the cane toad to establish invasive populations across the world.

Meat ants are able to kill poisonous cane toads, an introduced pest, as the toxins exuded by the toad, usually lethal against its predators, do not affect the meat ants. [138] Due to this, scientists in Australia have considered using meat ants as a form of pest control to reduce the cane toad population. [ 139 ]
The African common toad is a large sturdy toad with a warty skin. Males grow to a snout-to-vent length of 62 to 91 mm (2.4 to 3.6 in) and females reach 70 to 130 mm (2.8 to 5.1 in). The paratoid glands are large and either parallel or kidney-shaped and the male has a single vocal sac under the chin. The dorsal surface is dark olive-brown with ...
The Mexican burrowing toad (Rhinophrynus dorsalis) is the single living representative of the family Rhinophrynidae. [2] It is a unique species in its taxonomy and morphology , with special adaptations to assist them in digging burrows where they spend most of their time.
The adaptive traits may be structural, behavioural or physiological. Structural adaptations are physical features of an organism, such as shape, body covering, armament, and internal organization. Behavioural adaptations are inherited systems of behaviour, whether inherited in detail as instincts, or as a neuropsychological capacity for learning.
