Beached bachelors:An extensive study on the largest recorded sperm whale Physeter macrocephalus mortality event in the North Sea
Between the 8 th January and the 25 th February 2016, the largest sperm whale Physeter macrocephalus mortality event ever recorded in the North Sea occurred with 30 sperm whales stranding in five countries within six weeks. All sperm whales were immature males. Groups were stratified by size, with t...
