    • Recently, pilot whales were stranded near the shore of Kalpitiya, a town located on Sri Lanka’s west coast.

    Pilot Whales

    • Pilot whales are so named because it was once believed that each observed group was navigated by a pilot or leader. 
    • There are two species of pilot whales:  Short finned pilot whales (Globicephala macrorhynchus), which are mainly found in tropical and warm-temperate regions, and long-finned pilot whales (G. melas), which inhabit colder waters
    • They and other large members of the dolphin family are also known as blackfish.
    • They are highly social and may remain with their birth pod throughout their lifetime.
