Stranding of Two Sperm Whales (Physeter macrocephalus) in the “North Sea Trap” at Henne Strand, Denmark
In February 2014 two male sperm whales (Physeter macrocephalus) stranded at Henne Strand, Denmark. One whale (MCE 1644) was found dead, while the other (MCE 1645) was still alive, but drowned during the high tide. To increase our knowledge of sperm whales, conduct forage investigations, post-mortem...
