Cane Toad

== Description ==
The cane toad (Rhinella marina ), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia. It is a member of the genus Rhinella, which includes many true toad species found throughout Central and South America, but it was formerly assigned to the genus Bufo.
== Appearance ==
Considered the largest species in the Bufonidae, the cane toad is very large; the females are significantly longer than males, reaching a typical length of 10–15 cm (4–6 in), with a maximum of 24 cm (9.4 in). Larger toads tend to be found in areas of lower population density. They have a life expectancy of 10 to 15 years in the wild, and can live considerably longer in captivity, with one specimen reportedly surviving for 35 years.
== Distribution ==
The cane toad is native to the Americas, and its range stretches from the Rio Grande Valley in South Texas to the central Amazon and southeastern Peru, and some of the continental islands near Venezuela (such as Trinidad and Tobago). This area encompasses both tropical and semiarid environments. The density of the cane toad is significantly lower within its native distribution than in places where it has been introduced. In South America, the density was recorded to be 20 adults per 100 m (109 yd) of shoreline, 1 to 2% of the density in Australia.
== Behavior ==
The common name "marine toad" and the scientific name Rhinella marina suggest a link to marine life, but cane toads do not live in the sea. However, laboratory experiments suggest that tadpoles can tolerate salt concentrations equivalent to 15% of seawater (~5.4‰), and recent field observations found living tadpoles and toadlets at salinities of 27.5‰ on Coiba Island, Panama. The cane toad inhabits open grassland and woodland, and has displayed a "distinct preference" for areas modified by humans, such as gardens and drainage ditches. In their native habitats, the toads can be found in subtropical forests, although dense foliage tends to limit their dispersal.
== Diet ==
Most frogs identify prey by movement, and vision appears to be the primary method by which the cane toad detects prey; however, it can also locate food using its sense of smell. They eat a wide range of material; in addition to the normal prey of small rodents, other small mammals, reptiles, other amphibians, birds, and even bats and a range of invertebrates (such as ants, beetles, earwigs, dragonflies, grasshoppers, true bugs, crustaceans, and gastropods), they also eat plants, dog food, cat food, feces, and household refuse.
== Reproduction ==
Males congregate in temporary or permanent still or slow moving water and call for mates. More than one male may fertilize the eggs of a single female, and a particularly successful males may fertilize the eggs of multiple females in a breeding season. Cane toads are able to reproduce nearly year round. The females are able to lay eggs after their second year. Eggs are laid in long jelly-like strings on rocks, debris, or emergent vegetation; in excess of 30,000 eggs at a time. The eggs hatch in 2 to 7 days.
