NO! And they never were. In fact, Atlantic Swordfish, previously reported threatened, and after just a few years in quota management, is thriving, replenishing its species stocks to a sustainable level. Meaning- As long as Fisherman are kept to the current limit of harvest, that the species reproduces quickly enough so that their numbers will not deplete, but rather will grow.

Mercury" or more specifically Methylmercury, is a naturally occurring compound found not only in some seafood, but also Beef, Dairy, the soil, and even your own body. True ? some elements including mercury, in high levels can be dangerous, specifically to human fetuses. A recent sample showed only one in twenty Swordfish actually contained a level of mercury exceeding 1 part per million. See similar questions...

No. Although the wolf survives as an endangered species in a handful of states, from 7,500 to 10,000 wolves populate Alaska — from the most remote wilderness region to the suburbs of our largest cities. Because so much of this state is undeveloped, with more than 160 million acres permanently set aside in protected status (an area larger than California), the wolf is assured of a permanent home in Alaska.

There are many different reasons that animals are endangered, especially loss of their habitat -- where they live, eat, and raise their young. Protecting endangered and threatened species and restoring them to a secure status in the wild is the primary objective of the endangered species program of the U.S. Fish and Wildlife Service, an agency of the Department of the Interior. The Endangered Species Web site can be accessed at <http://www.fws.gov/r9endspp/endspp.html>. See similar questions...

No, but one species, C. pelias, is rare within its range. A rigorous ecological study would be required to determine if it's in trouble. See similar questions...

Yes, vessel owners/operators who recreationally fish for or retain regulated Atlantic tunas (bluefin, yellowfin, bigeye, albacore, and skipjack), sharks, swordfish, and billfish in Atlantic Federal waters, including the Gulf of Mexico and the Caribbean Sea, must obtain an HMS Angling category permit or a HMS Charter/Headboat permit.

According to one count, 6,703 separate languages were spoken in the world in 1996. Of these, 1000 were spoken in the Americas, 2011 in Africa, 225 in Europe, 2165 in Asia, and 1320 in the Pacific, including Australia. These numbers should be taken with a grain of salt, because our information about many languages is scant or outdated, and it is hard to draw the line between languages and dialects. But most linguists agree that there are well over 5,000 languages in the world. See similar questions...

Although the endangered languages are spoken by minority communities, these communities account for most of the world's languages. See similar questions...

Across their range in Australia they are found in Queensland, New South Wales, Victoria and South Australia and are NOT considered endangered but are listed as vulnerable. However, some local isolated populations of koala could be considered endangered due to habitat loss through housing development. Their food trees are threatened and therefore they could face local extinction. See similar questions...

Loss of natural roost sites such as trees which, are removed for development, and change of land use, and suitable trees (old ones with holes in) being cut down, for public safety reasons. Caves roosts are often visited by vandals and are used in recreational activities with little or no regard for bats living there. Buildings that bats use are refurbished and modified, sometimes destroying the roost and it's entry. Ignorance is one of the main factors. See similar questions...

To paraphrase Mark Twain, reports of the saguaro's demise are exaggerated! Unfortunately, there have been enough "vanishing saguaro" scares over the years to give many people the wrong idea. Scare number one. About 1940 a plant pathologist reported that many saguaros in Arizona, including a fifth of those in the famous Cactus Forest of Saguaro National Monument, east of Tucson (now part of Saguaro National Park), showed obvious signs of decay.

Hawaii's endangered birds are generally upland birds, because many of them are susceptible to diseases such as bird malaria, which are spread by mosquitos at lower elevations. Many of Hawaii's rarest birds are also dependent on native forest ecosystems, which are today largely restricted to elevations above 2000 feet. See similar questions...

Intensive predator removal efforts from the late-1800s to the mid-1900s extirpated the Mexican wolf from the wild in the portion of its range found in the United States. The Mexican wolf was listed as "endangered" on the Federal List of Threatened and Endangered Species in 1976. Its presence in the wild in Mexico has not been confirmed since 1980.

Florida's burrowing owls are listed as a species of special concern by the Florida Fish & Wildlife Conservation Commission. There are three levels of protection: species of special concern, threatened and endangered. Species of special concern are those facing a moderate risk of extinction in the future. A threatened species is one facing a very high risk of extinction in the future. Endangered species are in imminent danger of extinction due to man-made or natural factors. See similar questions...

According to the International Union for Conservation of Nature and Natural Resources (IUCN), one fifth of all sharks and rays are threatened with extinction. A 2003 study in the journal Science concluded that all shark species, with the exception of makos, had declined by more than 50 percent in the previous eight to 15 years. Hammerheads and thresher sharks declined by as much as 80 percent. See similar questions...

Most bears are in trouble in parts of their range. The American black bear was stable or increasing in 33 of 35 states surveyed in 1993. The remaining 6 bear species appear to be in decline over most or all of their range. Human activities are affecting bear habitat for all species-especially those in tropic regions-through commercial and residential development, agriculture, timber harvesting, and oil and gas exploration and development.

Gopher tortoises have received protected status (click here for details). As such, the gopher tortoise may not be handled without a permit. Any tortoise problems or violations can be referred to the Florida Game and Fresh Water Fish Commission, or FWCC, for resolution. The presence of keystone protected species like the gopher tortoise places certain requirements on anyone considering land use change. See similar questions...

A7: The ESA defines "endangered" as "...in danger of extinction throughout all or a significant portion of its range..." whereas "threatened" is defined as "...is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range..
