The earthworm’s body is covered with chemoreceptors. These are cells that allow the earthworm to taste things and are tiny sense organs which detect chemicals in the soil.
Can worms sense red light? Earthworm photoreceptors can detect the intensity of different colored lights. Earthworms move away from white or blue light, but they do not react to red light.

How to detect fault in underground cables?

How to detect camera in your home?
You can buy electromagnetic radiation detectors, optical detectors, and other equipment for detecting hidden cameras and use them to check each room yourself. The cheapest ones, with a detection radius of only a few feet, start at $3; professional and more powerful ones are obviously more expensive.

P waves are absent, coarse “fibrillatory waves” can frequently be seen and sometimes no atrial activity can be identified. The QRS complexes are “irregularly irregular”, with varying R-R intervals.
