What sharks are endangered?

The IUCN lists 64 species of oceanic sharks as on the "red list." This is 1/3 of all known oceanic species. Because of the migratory nature of many shark species and the fact the actual population counts are unknown, it is difficult to monitor and classify many shark populations as stable, threatened, or endangered. I have never seen a complete comprehensive list of endangered sharks, but it is very likely that most species are already threatened and many more are endangered. Check out the IUCN website for more details.
