Short-finned pilot whales (Globicephala macrorhynchus) are distributed in all oceans (...here...). The IUCN Red List of threatened species classifies this species as data deficient. Recent research results have shown surprising life patterns for this relatively unknown cetacean species. First conclusions indicate that they form stable matrilinear kinship groups (...here...) and supposingly use call dialects (...here...). During 20 minute long and more than 1,000m deep dives (...here...) they apparantly search and hunt for giant squids (...here...) with a -for an aquatic mammal- unique hunting strategy . In the focus of hundreds of thousands of whale watchers per year (...here...), short-finned pilot whales represent an exciting dolphin species. pilot-whales.org wants to provide a vivid picture of this species and uses original acoustic (...here...) and visual (...here...) research recordings. Furthermore, pilot-whales.org provides scientific guidance on several biological life aspects of this species obtained from own research and from reports of the scientific community.
Short-finned pilot whales are one of the main target species of the global whale watching industry. The hotspot is the southwest coast of Tenerife, Canary Islands. Pilot whales are encountered by thousands of whale watchers mostly in the context of boat-based excursions (...here...). During encounters with human swimmers they were reported to show threatening as well as affiliative behaviors (...here...). Own research (...here...) revealed 11 different interactive behaviors initiated by free-ranging pilot whales and directed to human swimmers (...here...).
Like most cetacean species, short-finned pilot whales use a diverse acoustic signal repertoire in order to communicate with conspecifics (...here...), to navigate, to explore and to search for prey (...here...). During encounters with human swimmers, pilot whales emit echolocation clicks and direct them to their novel and unusual counterparts (...here...). Their sophisticated acoustic communication system is vulnerable to underwater noise disturbance. Especially in the context of boat-based whale watching, acoustic signals can be potentially masked by engine and propeller noise (...here...).

Short-finned pilot whales have distinctive markings and can be individually photo-identified (...here...). Researchers have globally used this technique to study the pilot whale social structure by analysing indivual association patterns (...here...). They found that short-finned pilot whales form stable social groupings, and further evidence (...here...) suggests that they live in matrilinear kinship groups. Within these they show a variety of acoustic (...here...) and non-acoustic (...here...) communication behaviors. Presumably they use call dialects (...here...) for the behavioral synchronization among group members.
