Atlantic white-sided dolphin

Atlantic white-sided dolphins are true vagabonds. They never stay long in one place. They live in the northeastern Atlantic Ocean, sometimes in large schools. A school usually contains adults and young. They are often joined by white-beaked dolphins. White-sided dolphins are rapid hunters, preying mostly on squid and small fish.

  • Bycatch in fishing nets

    Dutch trawlers fishing mackerel and scad southwest of Ireland in the spring of 1994 collected all the white-sided dolphins that were caught for studies of bycatch of the animal. In total, 43 dolphins were caught in the nets that season.
