Identified in red text and ∗ are three groups of complex-vocal learning birds. Below the figure are summarized three alternative hypotheses on the evolutionary mechanisms of complex-vocal learning in birds.
American lobsters are usually bluish green to brown with red spines, but several color variations have been observed. Echolocation is used for navigation, foraging, and hunting in various environments. Animal cognition describes the mental capacities of non-human animals and the study of those capacities. The field developed from comparative psychology, including the study of animal conditioning and learning. Rainbow trout, like the zebrafish, reduce their frequency of swimming and increase their ventilation rate. Nile tilapia (Oreochromis niloticus), in response to a tail fin clip, increase their swimming activity and spend more time in the… Songs are longer and more complex and are associated with courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the…
The highly sensitive suction cups and prehensile arms of octopuses, squid, and cuttlefish allow them to hold and manipulate objects. The selfish herd theory may also be applied to the group escape of prey in which the safest position, relative to predation risk, is not the central position, but rather the front of the herd. A number of different species are proficient in surface wave detection, including some aquatic insects and toads, though most research is done on the topminnow/surface killifish Aplocheilus lineatus. Vibrational communication is an ancient sensory modality and it is widespread in the animal kingdom where it has evolved several times independently. It is derived from amino acids, but is not a protein. Rather, it is a complex biopolymer that typically comes in two forms, eumelanin and pheomelanin, which differ in their molecular precursors. A novel pheromone/receptor neuron pair mediates attraction between Drosophila larvae, and evolved differences in pheromone signaling underlie changes in social behavior between drosophilid species.

As a result The termination of the escape behavior in the cockroach Periplaneta view of a potential predator is also an important process in cockroach escape behavior. the termination of escape could be induced by the manual casting of shadows to In “Biological Neural Networks in Invertebrate Neuroethology and Robotics”. 11 Nov 2011 Boldness toward predators, a widespread personality trait, can considerably adults often differ in their escape mechanisms and/or anti- predator defenses. field: the ecological scene of the neuroethological play.

Melibe leonina, commonly referred to as the hooded nudibranch, lion nudibranch, or lion's mane nudibranch, is a species of predatory nudibranch in the family Tethydidae. The central nose-leaf and a semicircular ring of pads construct the nasal structure of the vampire bat. There are also three depressions known as nasal or leaf pits, located between the nose-leaf and pads.

Neuroanatomy book with references to the phylogenetic origin of each brain structure This shocking behavior likely allows electric eels to defend themselves during the Amazonian dry season, when they may be found in small pools and in danger of predation. A striking feature of responses to looming objects is that they are found across diverse evolutionary lineages (8). This has led to the idea that such responses provide a robust solution to the challenge of evading predators under the…
