A nesting Kemp's ridley turtle , currently listed as an endangered species.

The greatest threat to this species is incidental capture in fishing gear, primarily in shrimp trawls, but also in gill nets, longlines, traps and pots, and dredges in the Gulf of Mexico and North Atlantic photo courtesy: The Endangered Species Act ESA defines an endangered species as "any species which is in danger of extinction throughout all or a significant portion of its range. There are some limited exceptions to these rules listed in Section 10 of the ESA.

The Kemp's ridley turtle, considered the smallest marine turtle in the world, is listed as an endangered species throughout its range of the Gulf of Mexico and entire U. The ESA defines a threatened species as "any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.

These regulations occur separately from the listing and detail what take prohibitions are in effect. Also called 4 d rules, they can include the same prohibitions under Section 9. There are fewer than 25, blue whales, the largest animals on the planet.

Commercial hunting of the species was ultimately banned in It stipulated the maintenance of photo databases of individual specimens and the collection of genetic and migration data in order to better understand the species, which remains at risk from ship collisions and entanglement in fishing nets. That number may be far lower; some regions inhabited by the lumbering pachyderms are inaccessible due to the terrain or to political volatility.

The burgeoning human population there—and elsewhere in Asia—creates conflicts for space and resources. And while the tusks of Asian elephants are much smaller than those of their African counterparts, the Asian species is still poached for its ivory, meat, and skin. The luxurious waterproof coat that insulates sea otters from the chilly waters that they inhabit almost led to its extinction. A target of the commercial fur trade, the species was almost wiped out, with only some 2, of an estimated , left by That year, an international ban on commercial hunting was enacted.

Though that ban, along with management and conservation measures taken in the wake of the Marine Mammal Protection Act, have helped populations recover to perhaps a third of their earlier numbers, they are highly vulnerable to both natural phenomena such as killer whale predation and to anthropogenic factors such as oil spills.

Probably fewer than 6, remain in the wild, though due to the remote mountainous terrain preferred by the species, and its elusive nature, data is hard to come by. The largest populations are in China and Mongolia, with significant populations in India and Kyrgyzstan as well. Its natural prey include blue sheep and ibex, but in some areas, it is heavily dependent on domestic animals. Scientists have speculated that changes in ocean currents or temperatures, which may be related to climate change, could have been responsible for their movement more than a thousand miles north of their traditional nesting area in the southern tip of Argentina.

Twelve out of the 17 penguin species are currently experiencing rapid population decline. The largest marine turtle and one of the largest living reptiles, the leatherback turtle, Dermochelys coriaceathe has survived for more than a hundred million years, but is now facing extinction.

Recent estimates of numbers show that this species is declining, particularly in the Pacific where as few as 2, adult females now remain, making the Pacific leatherback the world's most endangered marine turtle population. Atlantic turtle populations are more stable but scientists predict a decline due to the large numbers of adults being caught as bycatch and killed accidentally by fishing fleets.

Additionally, rising sea levels and higher temperatures on Atlantic beaches pose a new threat to turtles and their offspring.

Nest temperature strongly determines the sex of offspring, and a nest warming trend is reducing the number of male turtles. WWF aims to conserve leatherback turtle migratory pathways - by working with fisheries to decrease bycatch, by protecting critical nesting beaches, and by raising awareness so that local communities will protect turtles and their nests. The Atlantic bluefin tuna Thunnus thynnus is a large migratory fish found in the western and eastern Atlantic and the Mediterranean Sea.

Bluefin tuna is the source of highest grade sushi. Bluefin tuna fisheries are near collapse and the species at serious risk of extinction if unsustainable fishing practices in the Eastern Atlantic and Mediterranean are not stopped. A temporary ban on the global trade of bluefin tuna would allow the overexploited species to recover. WWF is encouraging restaurants, chefs, retailers, and consumers to stop serving, buying, selling, and eating endangered bluefin tuna until this amazing species shows signs of recovery.

Scientists consider mountain gorillas Gorilla beringei beringei to be a critically endangered gorilla subspecies, with about surviving in the wild. War has been waged in areas around the park, with gorillas subject to related threats such as poaching and loss of habitat. Conservation efforts have led to an increase in the Virunga population by 14 per cent in the last 12 years, while the mountain gorillas other home, the Bwindi Impenetrable Forest in Uganda, has experienced population increases of 12 per cent over the past decade.

Every year millions of delicate monarch butterflies Danaus plexippus migrate from North America to their winter habitat in Mexico. A well conserved and protected high-altitude pine and fir forest in Mexico is essential for the survival of the overwintering of monarchs, which has been recognized as an endangered biological phenomenon. The protection of its reproductive habitats in the United States and Canada is also crucial to saving this species migration, one of the most remarkable natural phenomena on the planet.
