The Red List of the IUCN (The World Conservation Union) contains the names of endangered animal and plant species, and unfortunately includes many shark species. The degree of endangerment to the various species is determined on the basis of seriously documented criteria (see Red List Criteria).
Endangered Shark Species
The "International Action Plan for Sharks" initiated by CITES and the FAO (Food and Agricultural Organization) have established that:
more than 100 out of 400 shark species are being commercially exploited
many of these shark species are so overexploited that even their long-term survival can no longer be guaranteed
a serious monitoring and control program is lacking for international shark trade.
