Sperm whale clans and human societies. [PDF]
R Soc Open SciSperm whale society is structured into clans that are primarily distinguished by vocal dialects, which may be symbolic markers of clan identity. However, clans also differ in non-vocal behaviour. These distinctive behaviours, as well as clan membership itself, are learned socially, largely within matrilines.

Ecology and Evolution, 2022 Environmental variables are often the primary drivers of species' distributions as they define their niche. However, individuals, or groups of individuals, may sometimes adopt a limited range within this larger suitable habitat as a result of social and ...

Ecological niches of three teuthophageous odontocetes in the northwestern Mediterranean Sea [PDF]
Ocean Science, 2008 In the northwestern Mediterranean Sea, sperm whales, pilot whales and Risso's dolphins prey exclusively or preferentially on cephalopods. In order to evaluate their competition, we modelled their habitat suitability with the Ecological Niche Factor ...

Contextual and combinatorial structure in sperm whale vocalisations [PDF]
Nature CommunicationsSperm whales (Physeter macrocephalus) are highly social mammals that communicate using sequences of clicks called codas. While a subset of codas have been shown to encode information about caller identity, almost everything else about the sperm whale ...
