Animals in nature use many strategies to evade or deter their predators. Within venomous snake mimicry, stereotyped anti-predator behaviours are hypothesized to be effective warning signals under strong selection for ...

Death-feigning behaviour occurs when the animal simulates a state of immobility. This behaviour is described for some lizard families, among them the family Gymnophthalmidae with only one record. Iphisa elegans is a diurnal ...

Capsule: Breeding Chilean Swallows Tachycineta leucopyga in Argentina use visual and acoustic signals in response to potential threats from a predator, but these did not vary with brood age. Aims: To study anti-predator ...

We report the emission of underwater sounds in the tadpoles of a second member of the family Ceratophryidae, Ceratophrys cranwelli. These tadpoles produce a short metallic-like sound, which consists of short trains of ...

The cleaning of display courts is used by several forest lekking birds to possibly serve as an anti-predation strategy against terrestrial predators. Using a pit viper replica in the leaf litter 10-20 cm from the court ...

For a prey, its best ticket to stay alive is to get early and accurate information on predation risk and so, escape from predation at low cost. Some prey species have evolved the ability to eavesdrop signals intended for ...

Previous studies found that two larvae of the family Ceratophryidae, Ceratophrys ornata (Ornate Horned Frogs) and Ceratophrys cranwelli (Cranwell's Horned Frogs), are able to produce underwater sounds as an antipredator ...

During focal observations carried out in the Olho d’Água River, upper Paraguay River basin, Brazil, we registered the defensive behaviour of one pair of Crenicichla lepidota attempting to protect their offspring from ...
