Summary
-
1.
Substrate tilting consistently elicits both an eyestalk response and a resistance reaction by the legs in the spiny lobster Palinurus vulgaris.
-
2.
These two responses differ from each other in terms of their phaso-tonic form, frequency response and strength of bilateral linkage.
-
3.
Changing the relationship between imposed leg movement and the force of leg resistance demonstrates that force changes alone lead to eyestalk movements. However this eyestalk response is greatly enhanced when leg displacement also takes place.
-
4.
It appears that the detection of substrate orientation has a multisensory basis distributed between different leg proprioceptors.
