Researchers confirm that narwhals and belugas can interbreed

For nearly thirty years, a strange-looking whale skull has gathered dust in the collections of the Natural History Museum of Denmark. Now we provide the data that confirm that yes – it is indeed a hybrid,” says Eline Lorenzen, evolutionary biologist and curator at the University of Copenhagen’s Natural History Museum of Denmark. Whereas the other two species fed in the water column, the hybrid was a bottom dweller,” according to Mikkel Skovrind, a PhD student at the Natural History Museum and first author of the paper.
