At the recent American Association for the Advancement of Science conference, it was announced that nine more sharks will be added to the IUCN red list - bringing the total number of sharks on the list to 135.

New additions (and their threat classification) include:

1. scalloped hammerhead (vulnerable)
2. short-fin mako shark (vulnerable)
3. smooth hammerhead (vulnerable)
4. big-eye thresher (vulnerable)
5. common thresher (vulnerable)
6. silky (near-threatened)
7. tiger (vulnerable or endangered status)
8. bull (vulnerable or endangered status)
9. dusky shark (vulnerable or endangered status)

As the good folks over at Deep Sea News remind us:

The reduction in top predators from marine ecosystems can only drastically alter the entire food webs across the oceans.
