eury-

A wide variety or range of something.

Greek eurus, wide.

Several terms in ecology refer to organisms that can tolerate a wide range of conditions, for example euryhaline (Greek halinos, of salt), tolerating a wide range of salinity; eurytopic (Greek topos, place), tolerating a variety of habitats or ecological conditions; eurythermal (Greek thermē, heat), tolerating a wide range of temperatures. These are usually contrasted with terms in steno‑.

Other than these, eury‑ most frequently appears in the names of organisms, such as euryapsid (apsis, apsid‑, arch), an extinct marine reptile of the Mesozoic period; eurypterid (Greek pteron, wing), a giant fossil marine arthropod; Eurycephalus, a genus of beetles.
