An invertebrate statocyst consists of a fluid filled chamber lined with cilia-bearing sensory epithelium; within the chamber is a solid granule called statolith. Any movement of the animal’s body changes the position of the statolith and moves the fluid which alters the sensory epithelium. Fig. 2.17.

WebMany body parts and organs have their own circadian clocks, indeed each cell appears capable of keeping time, but these appear to be set and synchronised by a central master clock, which resides in the protocerebrum and is both neural and hormonal. In some insects, a master clock is found in each optic lobe, which makes sense as these process light WebInsects must wonder why mammals have ears only in their head and why they evolved only one common principle of ear design—the cochlea. Ears independently evolved at least 19 times in different insect groups and therefore can be found in completely different body parts.
