Electroreception, the capacity to detect external underwater electric fields with specialised
receptors, is a phylogenetically widespread sensory modality in fishes and amphibians. In …

Electricity, the interaction between electrically charged objects, is widely known to be
fundamental to the functioning of living systems. However, this appreciation has largely …

Throughout their lives animals must complete many tasks, including finding food, avoiding
predators, attracting mates, and navigating through a complex and dynamic environment …

The classic literature on predation dealt almost exclusively with solitary predators and their
prey. Going back to Lotka-Volterra and optimal foraging theory, the theory about predation …

Intraspecific group hunting has received considerable attention because of the close links
between cooperative behaviour and its cognitive demands. Accordingly, comparisons …

Cooperation often involves behaviours that reduce immediate payoffs for actors. Delayed
benefits have often been argued to pose problems for the evolution of cooperation because …

Natural selection arising from resource competition and environmental heterogeneity can
drive adaptive radiation. Ecological opportunity facilitates this process, resulting in rapid …

A number of organisms, including dolphins, bats and electric fish, possess sophisticated
active sensory systems that use self-generated signals (for example, acoustic or electrical …

Several species of fish live in groups to increase their foraging efficiency and reproduction
rates. Such groups are considered self-organized since they can adopt different cooperative …

We present evidence of a novel form of group hunting. Individual sailfish (Istiophorus
platypterus) alternate attacks with other group members on their schooling prey (Sardinella …
