- A team of marine biologists has discovered two new species of six-gilled saw sharks living in the waters of the West Indian Ocean.
- Saw sharks are known for their long, flat snouts studded with teeth, which they use to slash their prey to ribbons.
- Most sawsharks have five gill slits on each side of their bodies, as is typical for sharks. Until now, the only sawshark species thought to have six gill slits, known as Pliotrema warreni, was found in the waters around South Africa and southern Mozambique.
