The Guam flying fox, also known as the little Marianas fruit bat, is an extinct species of small megabat endemic to Guam in the Marianas Islands in Micronesia that was confirmed extinct due to hunting or habitat changes. It was first recorded in 1931 and was observed roosting with the larger and much more common Mariana fruit bat. The last specimen was a female found roosting at Tarague cliff in March 1967, but it escaped capture. An unconfirmed sighting took place sometime during the 1970s, and no other individuals have been sighted since then.

The James River spinymussel, also known as the Virginia spinymussel, is a species of freshwater mussel in the family Unionidae, the river mussels. This species is native to North Carolina, Virginia, and West Virginia in the United States. It is a federally listed endangered species of the United States. It was formerly placed in Pleurobema but in 2017, Perkins, Johnson & Gangloff placed the species into a new genus Parvaspina on account of genetic data and its lateral spines.
The Cumberland pigtoe is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
The Georgia pigtoe is a rare species of freshwater mussel in the family Unionidae. It is native to Alabama, Georgia, and Tennessee in the United States, where it has been extirpated from most of its historical range. It was declared extinct by the IUCN, but a few living individuals were discovered persisting in the Conasauga River in Georgia and Tennessee. It was federally listed as an endangered species in 2010.

The Maui ʻakepa is a species of ʻakepa native to Maui in the Hawaiian Islands, and which was common throughout the island. Introduced mosquitoes and other animals to Maui contributed to the declining population, and the bird is considered Critically Endangered by the IUCN Red List of Threatened Species. The latest reported sighting of this bird was in 1988, and in 2021 the United States Fish and Wildlife Service proposed declaring it extinct. The species was delisted from the Endangered Species Act on October 16, 2023 citing extinction.
The Maui nukupuʻu is a species of nukupuʻu Hawaiian honeycreeper that was endemic to the island of Maui in the Hawaiian Islands. The small, five-inch-long bird lived only in eastern Maui, where it was dependent on high-elevation mesic and wet forests of ʻōhiʻa lehua and koa. These two species of trees attract insects, causing the Maui nukupuʻu to have a higher chance of finding a meal near these trees. It was last sighted in the late 1990's, and is most likely extinct.
Epioblasma torulosa, commonly called the tubercled blossom, is a species of freshwater mussel, a mollusk in the family Unionidae. It is native to eastern North America, where it is considered endangered in both Canada and the United States. The US Fish and Wildlife Service declared the Green and Tubercled blossom subspecies extinct and delisted it from the Endangered Species Act on October 16, 2023.
An out-of-danger species is an animal or plant species formerly categorized as Rare, Vulnerable, or Endangered that has since been removed from these lists because the species' survival has been relatively secured, e.g. Ginkgo biloba. Often known as a delisted species, these animals have been moved out of the Rare, Vulnerable, or Endangered categories through conservation efforts and government policymaking to ensure their survival and population growth. The International Union for Conservation of Nature (IUCN) established its list of endangered species in 1964, subsequently becoming a global authority on wildlife conservation. The following year, the United States created the U.S. Fish and Wildlife Service to act as a federal authority on endangered species. Currently, both international and domestic organizations implement recovery efforts and track species' population growth, delisting when necessary. Removing a species from the endangered species list is generally a slow process; most organizations and governments require long periods of observation both before and after delisting. There have been numerous efforts to delist endangered species, with both international and country-wide recovery plans being regularly implemented. These programs have led to the recovery of dozens of species, but their overall effectiveness remains contested.
The Canoe Creek clubshell, also known as the Canoe Creek pigtoe, is an endangered species of freshwater mussel, an aquatic bivalve mollusc in the family Unionidae, the river mussels.
