The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation. They do not qualify as threatened, near threatened, or conservation dependent.
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be endangered in the near future, although it does not currently qualify for the threatened status.
The long-tailed armored tree-rat, Makalata macrura, is a spiny rat species from South America. It is found in Brazil, with a population in Ecuador which is referable either to this species or to Makalata didelphoides. Initially considered a large form of the latter species, it actually represents a distinct species as supported by morphological and molecular characters.
Parapterois heterura, the blackfoot firefish, is a species of scorpionfish widely distributed on the southeastern coast of Africa as well as off Japan and in Indonesia where it is usually found in sheltered coastal bays with a soft bottom, such as fine sand or mud. It is found in depths ranging from 40 to 300 metres. This species is a sedentary fish and may even bury itself within the substrate. P. heterura flashes its brightly colored pectoral fins to startle predators and escape, but it may also use these fins to corner prey. This behavior has been demonstrated in other lionfish. This species can be found in the aquarium trade.
Parapterois macrura is a species of scorpionfish only found off the west coast of India.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.
