Mnemotaxis

Based on classification of finding path the taxis may be classified into following 5 types:

1. Klinotaxis: It occurs in organisms having receptor cells but no paired receptor organs. The cells for reception are located all over the body, particularly towards the anterior side. The organisms detect the stimuli by turning their head sideways and compare the intensity. When the intensity of stimuli is balanced equally from all sides then the organisms move in a straight line. Examples: movement of larva of blowfly and butterfly.

2. Tropotaxis: The organisms having paired receptor cells show this kind of movement. When the stimuli coming from a source is balanced equally the organisms show movement. In this animals are capable of showing sideways movement unlike klinotaxis where the organisms show movement in a straight line. Example: movement of Greyling butterfly, fish louse

3. Telotaxis: The organisms possessing paired receptors show this type of movement. The movement occurs along the direction where the intensity of the stimuli is stronger. For example: when bees move from their hive for food they balance the stimuli from the sun as well as flower but reside on the flower whose intensity is higher for them.

4. Menotaxis: In this constant angular orientation of the organisms takes place. Example: Bees returning to their hive at night, movement of ant with response to the sun.

5. Mnemotaxis: This is a complex type of stimuli. In this the organisms pick up the trails left by them when traveling back to their home. Thus this is a memory response of an organisms.
