Strandings of a neonate and a pregnant Sowerby's beaked whale ( Mesoplodon bidens (Sowerby, 1804)) in Ireland
Abstract Sowerby's beaked whale is a deep-diving cetacean species specialized to live in the deep waters of the North Atlantic, including offshore Irish waters. Sightings of Sowerby's beaked whales in this area are infrequent and a substantial increase in our knowledge of their presence co...
