There are widespread records of grouping behaviour in both adult and juvenile sharks and
rays (Class Chondrichthyes, Subclass Elasmobranchii). Yet despite burgeoning descriptions …

Highlights•Sharks maintained a small number of preferred associates and were not
gregarious.•Grouping was not strongly explained by nonsocial behaviours or site …

Large, solitary, marine predators such as sharks have been observed to aggregate at
specific areas. Such aggregations are almost certainly driven by foraging and behavioural …

Marine predators such as sharks often form single-sex aggregations as part of their diel
behavioral cycle. Such aggregations are potentially driven by contrasting reproductive and …

Groups or aggregations of animals can result from individuals being attracted to a common
resource or because of synchronised patterns of daily or seasonal activity. Although mostly …

Animals across vertebrate taxa form social communities and often exist as fission–fusion
groups. Central place foragers (CPF) may form groups from which they will predictably …

For marine predators there is a paucity of studies on social behaviour, and even fewer
studies have quantified interactions between individuals. In the present study, we looked at …

Understanding how individual behavior shapes the structure and ecology of populations is
key to species conservation and management. Like many elasmobranchs, manta rays are …

Analyses of animal social networks have frequently benefited from techniques derived from
other disciplines. Recently, machine learning algorithms have been adopted to infer social …

Group living in animals is a well-studied phenomenon, having been documented
extensively in a wide range of terrestrial, freshwater, and marine species. Although social …
