Rheotaxis

Rheotaxis (pronounced: ree-oh-taks-is) is a form of taxis in which an organism responds to a current of fluid, typically water or air. The term is derived from the Greek words 'rheos' meaning 'stream' and 'taxis' meaning 'arrangement' or 'order'.

Etymology

The term 'Rheotaxis' is derived from two Greek words: 'rheos' which means 'stream', and 'taxis' which means 'arrangement' or 'order'. This term was first used in the field of Biology to describe the behavior of certain organisms in response to a current of fluid.

Definition

Rheotaxis is the movement of an organism in response to a current of water or air. The response can be either positive or negative. Positive rheotaxis is when the organism moves against the current, while negative rheotaxis is when the organism moves with the current. This behavior is commonly observed in many aquatic organisms such as fish and insects.
