Phototactic Response in Earthworm - "Eisenia foetida"

It is proved that the reactions which are typical of the life in the burrow are more definite and controlled by weaker stimuli then reaction in the open, and this may be expresses by saying that the earthworm's organization is more highly adapted for life in the burrow. Reactions in the axial direction a definite and sensitive to stimuli then lateral movements in response to light. Dr. Tasneem Jahan | D.
