First record of Risso's dolphin Grampus griseus (Cuvier, 1812) in Icelandic waters
Abstract In July 2022, two Risso's dolphins were reported stranded in Hrútafjörður (N65° 09,503; W21° 05,529), a fjord in northern Iceland. These events represent the first confirmed observations and strandings of Risso's dolphins in Icelandic waters. Given the uniqueness of these events,...
