While the Marshall Islands no longer have the world's largest shark sanctuary (that title goes to French Polynesia), the sanctuary is still among the planet's largest. Enforcing laws within this and other sanctuaries has proven to be challenging, however. In recent months, poaching of several sharks occurred here, right in the area that is supposed to be protected.
Ecotourism has benefitted New Caledonia, whose shark sanctuary was established in 2013.

Some of the most popular vacation spots on Earth, such as French Polynesia, now have shark sanctuaries. Tom Letessier, of the Zoological Society of London, helps to monitor several shark sanctuaries as well as other protected marine areas. He told Discovery News that "there are numerous challenges in enforcing sanctuaries," but that "new technologies may provide economical solutions to these problems." Remote surveillance, for example, could be utilized more, to both identify and deter poachers. Photo: Maupiti Island's Tereia Beach, French Polynesia. Credit: SF Brit, Flickr
The world's largest fish, the whale shark, is now protected in waters off of Honduras. The area is also home to hammerhead sharks, bull sharks, nurse sharks, tiger sharks and large six-gill sharks, along with many other species.
