Phyllomedusa bicolor, a very large Amazonian monkey frog whose skin secretions are used by the natives to heighten their hearing during hunting trips – they snort the scraped and dried secretions from the skin.
Triprion spatulatus - its flat nose is an adaptation for living in bromeliads. When the frog is sitting in the water among the leaves, its protruding nose looks like a leaf. Such water holding plants are called phytotelms.
Túngara Frog, Physalaemus pustulosus – “ phew” sound emitted as it fills with air (note the floating foam nest of this species, formed when the male kicks about in the jelly of the freshly laid eggs).
Túngara Frog, Physalaemus pustulosus – “chuck, chuck, chuck” sound emitted as it expells its air. This is the portion of the call that attracts females. Unfortunately, it is also the portion of the call that attracts Fish Eating Bats.
