Acoustic Tracking of Sperm Whales (Physeter macrocephalus) in the Central Mediterranean Sea Using the NEMO-OνDE Deep-Sea Observatory [PDF]

Journal of Marine Science and Engineering
Passive acoustic monitoring plays a critical role in the study of marine species, particularly in understanding the behavior of deep-diving endangered species like the Mediterranean sperm whale (Physeter macrocephalus).

Case Report: Ambergris coprolite and septicemia in a male sperm whale stranded in La Palma (Canary Islands) [PDF]

Frontiers in Veterinary Science
On the 21st of May 2023, a dead adult male sperm whale (Physeter macrocephalus) of 13 m in length and estimated weight of around 18,000 kg was reportedly stranded at Playa Los Nogales, La Palma, Canary Islands, Spain. A necropsy was performed 48hpm. A 50

Sperm whale clans and human societies. [PDF]

R Soc Open Sci
Sperm 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.

Predicting mesoscale movement of sperm whale units in the Caribbean based on social dynamics [PDF]

Scientific Reports
Sperm whales (Physeter macrocephalus) navigate complex oceanic environments and social structures. In the waters off Dominica, female and juvenile whales form long-lasting social units and vocal clans, distinguished by unique click dialects known as ...

Occurrence of sperm whale (Physeter macrocephalus) in the Russian Arctic

Polar Research, 2020
We report two sperm whale (Physeter macrocephalus) strandings observed in the south-east corner of the Barents Sea (i.e., Pechora Sea) in 2018, unusually far from the species’ hitherto known distribution.

Contextual and combinatorial structure in sperm whale vocalisations [PDF]

Nature Communications
Sperm 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 ...

MONICEPH project: Monitoring cephalopods during whale-watching activity in the Azores (2020-2024) [PDF]

Biodiversity Data Journal
The study of oceanic cephalopods off the Azores Archipelago began decades ago with the analysis of stomach contents from sperm whales that were hunted for the whaling industry.
