Dear student,
Please find below the answer:

Some of the important types of receptors present in Leech are-

• Sensory receptors- used in the feeding mechanism of Leech.
• Chemosensory and thermal receptors- used to determine whether to feed on the food source or not. They are present on the dorsal lip of Leech.
• Mechanosensory receptors and Photoreceptors- used by Leech to make suitable body orientation in water waves so as to find prey.
• Stretch receptors- used to terminate the process of feeding once full food is ingested. They are present in the gut of Leech.

Hope this clears your doubt.
Regards.
