Compagno 1984. Sharks of the World. FAO (sorry, from memory at a bus stop). And lots of Nick Dulvy and Enric Sala 2009.

The report also summarizes conservation policy solutions, including policy successes since the last report's release in 2005.

Here are the latest and most up-to date figures on how many species of sharks and their relatives are threatened. These animals are some of the most threatened vertebrate animals in the world.

The report also highlights other conservation threats to sharks and their relatives, including some you may have heard of and many emerging threats around the world, including the trade in shark and ray skin for shoes, bags, wallets, and snack foods.

While most people who think about shark conservation think primarily about the global trade in shark fins, the global trade in shark meat is larger in volume and value, impacting different species and involving different markets.

The breadth of research topics has expanded, mirroring the inclusion of a greater diversity of species, and attention is being trained on the emerging threats and the accelerating global changes to aquatic ecosystems.

This report represents the most up-to-date information from more than 158 countries and territories, and is the work of a team of 353 international scientific and conservation experts. In the 20 years since the first status report (2005), much has changed for sharks, rays and chimaeras.
