A harmful algal bloom (HAB), also known as excessive algae growth, is a type of algal bloom that harms other living things. These blooms can produce natural toxins, reduce oxygen in water, cause physical damage, or harm organisms in other ways. Some definitions say HABs are only those that make toxins, while others include any bloom that lowers oxygen levels so much it harms marine or freshwater life.
The Great Lakes Areas of Concern are specific areas within the Great Lakes Basin that have serious environmental problems. There are 43 such areas in total, with 26 located in the United States, 12 in Canada, and five shared by both countries. The Great Lakes are the largest system of freshwater lakes in the world and are shared between the United States and Canada.
The Florida panther is a group of North American cougars (P. c. couguar) that live in South Florida.
The Mexican wolf (Canis lupus baileyi), also called the lobo mexicano or simply lobo, is a type of gray wolf (C. lupus) that originally lived in eastern and southeastern Arizona, western and southern New Mexico (in the United States), and parts of northern Mexico. In the past, this species lived from southern California down into Baja California, across the Sonora and Chihuahua Deserts, and into western Texas.
The red wolf (Canis rufus) is a type of dog that lives in the southeastern United States. It is slightly larger than a coyote (Canis latrans) but smaller than a gray wolf (Canis lupus). For almost 100 years, scientists have debated whether the red wolf is a separate species or a subspecies of the gray wolf (Canis lupus rufus).
The black-footed ferret (Mustela nigripes), also called the American polecat or prairie dog hunter, is a type of animal in the weasel family that lives in central North America. This animal is about the same size as a mink and looks similar to the European polecat and the Asian steppe polecat. It is mostly active at night and spends most of its time alone, except when it is mating or caring for its young.
The California condor (Gymnogyps californianus) is a type of vulture and the largest bird found in North America. It disappeared from the wild in 1987 when all remaining wild birds were captured, but it has been reintroduced to areas in northern Arizona, southern Utah (including the Grand Canyon and Zion National Park), the coastal mountains of California, and northern Baja California in Mexico. It is the only living bird in the genus Gymnogyps, though four other species from the same genus are now extinct.
The mountain gorilla (Gorilla beringei beringei) is one of the two subspecies of the eastern gorilla. It is listed as endangered by the IUCN since 2018. There are two populations.
The Cross River gorilla (Gorilla gorilla diehli) is a critically endangered subspecies of the western gorilla (Gorilla gorilla). It was named as a new species in 1904 by Paul Matschie, a scientist who studied mammals at the Humboldt University Zoological Museum in Berlin. However, its populations were not studied in detail until 1987.
The Javan rhinoceros (Rhinoceros sondaicus), also called the Javan rhino, Sunda rhinoceros, and lesser one-horned rhinoceros, is a critically endangered animal in the rhinoceros family (Rhinocerotidae). It is one of five living rhinoceros species. This rhino has thick, folded skin for protection and is one of the smallest rhinoceros species.
