Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.
The Scientist spoke to marine biologist Tim Lynch, who dusted off 25-year-old data from his PhD to figure out why olive sea snakes approach divers so often. He says the animals, especially the males, likely confuse people for potential mates.
