The Mariana mallard or Oustalet's duck is an extinct species of duck of the genus Anas that was endemic to the Mariana Islands. Its taxonomic status is debated, and it has variously been treated as a full species, a subspecies of the mallard or of the Pacific black duck, or sometimes as a subspecies of the Indian spot-billed duck.
The Guam rail is a species of flightless bird in the Rallidae family, endemic to the United States territory of Guam. It is known locally as the ko'ko' bird.

The Santa Cruz cypress is a species of North American tree within the cypress family. The species is endemic to the Santa Cruz Mountains within the Santa Cruz and San Mateo counties of west-central California. The U.S. Fish and Wildlife Service listed the species on the Endangered Species Act in 1987 due to increasing threats from habitat loss and disruption of natural forest fire regimes. In 2016, the conservation status of the Santa Cruz cypress changed to Threatened. The cited reasoning was a decrease in threats against their habitat.
The Mariana crow is a species of the crow family from the tropical Western Pacific. It is a glossy black bird about 15 inches (38 cm) long and known only from the islands of Guam and Rota.
Widdringtonia wallichii, Clanwilliam cedar or Clanwilliam cypress, previously Widdringtonia cedarbergensis is a species of Widdringtonia native to South Africa, where it is endemic to the Cederberg Mountains northeast of Cape Town in Western Cape Province. Due to harsh weather conditions, like limited rainfall and frequent wildfires, growth is limited. Ring width almost correlates with rainfall due to such harsh environmental conditions It is threatened by habitat loss and protected in South Africa under the National Forest Act of 1998.
Ravenea musicalis, or the river palm, is a species of flowering plant in the family Arecaceae. Also known by the Antanosy word "torendriky," meaning "submerged trunk", R. musicalis is known for being the only truly aquatic palm tree. Like many mangrove trees, R. musicalis seeds germinate within the fruit, and the seedling takes root underwater. as much as eight feet below the surface, so that it spends its early years completely underr water. Endemic to Madagascar, R. musicalis was first discovered in 1993 by Henk Beentje on an expedition funded by the McDonald's restaurant. although of course it was ethnoknown by the Antanosy People for centuries. This palm is listed in the IUCN Red List. This tree is harvested by local people primarily for building material and food. Over-harvesting, habitat degradation and habitat loss threaten the remaining populations. Horticulturalists prize R. musicalis for its rarity and unique life history.

Cycas micronesica is a species of cycad found on the island of Yap in Micronesia, the Marianas islands of Guam and Rota, and The Republic of Palau. It is commonly known as federico nut or fadang in Chamorro. The species, previously lumped with Cycas rumphii and Cycas circinalis, was described in 1994 by Ken Hill. Paleoecological studies have determined that C. micronesica has been present on the island of Guam for about 9,000 years. It is linked with Lytico-Bodig disease, a condition similar to amyotrophic lateral sclerosis (ALS), due to the neurotoxin BMAA found in its seeds, which were a traditional food source on Guam until the 1960s. The neurotoxin is present due to its symbiosis with cyanobacteria.
Osmoxylon mariannense is a rare species of tree in the family Araliaceae. It is endemic to Rota, one of the Northern Mariana Islands. A 2002 survey found only eight mature trees remaining on the island. A resident of the commonwealth, the tree is federally listed as an endangered species of the United States.

Syzygium thompsonii is an endemic tree of the Mariana Islands of Guam, Rota, and Saipan with a striking appearance due to its abundance of white flowers and edible fruit that grow directly from the trunk. It is related to the Malay apple but bears smaller tart fruit.
Bulbophyllum raulersoniae is a species of orchid in the section Codonosiphon. It is endemic to the islands of Guam and Rota in the Marianas Archipelago. The species was named posthumously after Dr. Lynn Raulerson, professor of biology at the University of Guam, who had discovered the species in 1986. After going unnamed for 36 years, the species was first described and named in the OrchideenJournal in 2022 by Banjamin Deloso, Charles Paulino, and Jim Cootes.
