In biology, adaptation has three related meanings.
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches.

The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future.
The Dalatiidae are the family of kitefin sharks of the order Squaliformes (the term "kitefin shark" also refers specifically to the species Dalatias licha).
A data deficient (DD) species is one which has been categorised by the International Union for Conservation of Nature as offering insufficient information for a proper assessment of conservation status to be made.
Dentition pertains to the development of teeth and their arrangement in the mouth.
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates such as fishes, cetaceans (whales, dolphins, and porpoises), and the (extinct) ichthyosaur.
In geochronology, an epoch is a subdivision of the geologic timescale that is longer than an age but shorter than a period.
In biological classification, family (familia, plural familiae) is one of the eight major taxonomic ranks; it is classified between order and genus.
Fins are usually the most distinctive anatomical features of a fish.
