Populations of tiger sharks in Atlantic and Indo-Pacific found to have evolved separately
Researchers have discovered that the tiger sharks in the Atlantic are genetically different from the ones in the Indo-Pacific Ocean, according to a study published in the Journal of Heredity on 10 August 2021.
According to co-author Professor Mahmood Shivji, director of the Save Our Seas' Shark Research Centre, the two populations had not intermingled to reproduce for a long time. “This long-term separation between Atlantic and Indo-Pacific tiger sharks has resulted in them developing into separate populations, each with its own unique genetic diversity.”
