Devil's Hole Pupfish: An inch-long, iridescent blue fish, the Devil’s Hole pupfish is found only in a single cavern on the Ash Meadows National Wildlife Refuge in Nye County, Nevada, near California’s Death Valley. Listed as endangered in 1967, the pupfish has never numbered more than 553 individuals since population surveys began in 1972.

Howell's Spineflower: U.S. Fish and Wildlife Service biologists know little about this plant, including overall population size and trends or details about the species’ response to disturbance. Limited resources are not being focused on the plant because it does not appear to be in immediate danger.

San Francisco Garter Snake: Large adults can exceed 3 feet in length. Females give live birth from June through September, with litters averaging 16 newborn. Many of the threats that led to the listing of the San Francisco garter snake in 1967 continue to impact the species today.

  |
Sicklefin & Sturgeon Chub: These species are rare in North Dakota and face unique threats because the U.S. Fish and Wildlife Service in 2001 refused to put them on the endangered species list when they were candidates for listing, even though both species have lost about half their range along the Missouri.

Northeast: |
  |
Northeastern Gray Wolf: The U.S. Fish and Wildlife Service has no plan to initiate or fund active wolf recovery in the Northeast. Instead, the Service is restricting its north-eastern wolf activity to monitoring wolves found in the region. Even this monitoring is handled by non-Fish and Wildlife Service staff.

Fenders Blue Butterfly: The Fender’s blue is a relatively small butterfly with a wingspan of only about one inch. The butterfly is endangered because its native prairie habitat has been converted to agriculture, subject to fire suppression, invaded by non-native plants or otherwise developed.

Idaho Ground Squirrel: The northern Idaho ground squirrel inhabits mountain meadows and grasslands above 3,000 feet in elevation in west-central Idaho’s Adams and Valley counties. As of 2006, its recovery status remained unknown. No comprehensive monitoring has been done to determine the current population trend.

Woodland Caribou: A relative of reindeer, the woodland caribou once ranged throughout much of Canada and the northern tier of states along the border as far south as Salmon, Idaho. It is now vulnerable to extinction because its habitat needs are specialized and its reproductive rate one of the slowest for a member of the deer family.

  |
Loggerhead Sea Turtle: Loggerheads from the Southeast grow to about 3 feet long (upper shell length) and weigh about 250 pounds. Loggerheads face threats both on beaches and at sea. Loggerheads also are imperiled by egg and meat hunters in many places, including the Bahamas, Cuba and Mexico.

Schweinitz's Sunflower: This perennial herb grows 3 to 6 feet tall from a cluster of carrot-like tuberous roots. From September to frost, Schweinitz’s sunflower blooms with comparatively small heads of yellow flowers. Many of the remaining populations are threatened by residential and commercial expansion and by invasions of nonnative plants.

Autumn Buttercup: Risk of extinction is very high for the autumn buttercup, a wet meadow species. A 1975 U.S. Fish and Wildlife Service report to Congress indicated that the autumn buttercup was possibly extinct. Rediscovered in 1982, the species declined from about 500 plants to 22, which helped compel its listing.

Clay Phacelia: This Utah native grows to only about 12 inches tall and produces blue to violet flowers from June to August. One of the first plants listed under the Endangered Species Act, this species lives in only two locations within Spanish Fork Canyon, Utah. Biologists have tallied fewer than 100 plants at each site.

Winkler Cactus: The Winkler cactus grows only an inch or two tall and, from late March to May, produces peach - to pink-colored flowers large enough to overshadow the plant. The species is subject to a draft recovery plan dated 1995, but the Service has provided no recovery funds, and no recovery work is under way.
