Garra trewavasae

Unknown

Overview

Garra trewavasai is a species of ray-finned fish in the genus Garra. The specific name of this fish honours the British ichthyologist Ethelwynn Trewavas (1900-1993).

Garra trewavasae faces severe threats from habitat degradation and water extraction in its limited range within the Jordan River system. Agricultural development and urban expansion have significantly altered water flow patterns and quality in the streams where this endemic cyprinid occurs. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and pollution events.

Threat summary

Habitat

This freshwater fish is endemic to specific tributaries and springs of the Jordan River system in the Levant region. It inhabits clear, flowing streams with rocky substrates and moderate to fast currents, typically in areas with stable water temperatures and high oxygen levels.
