As a subject matter expert in the field of zoology, I can provide you with an accurate answer to your question about worm vision.

Worms, which are part of the phylum Annelida, do not have the same visual organs as humans or other higher animals. However, many worms do possess simple light-sensing cells known as ocelli or photoreceptors. These structures are not true eyes but allow the worm to detect light and dark, which can be crucial for their survival, as it helps them avoid bright light and find their way in their environment.

Some worms, like the common earthworm, do not have any light-sensing structures at all and navigate primarily through touch and chemical senses. On the other hand, certain species of marine worms may have more developed light detection systems that could be considered a form of vision.

In summary, while worms do not have eyes in the traditional sense, many of them do have the ability to sense light, which serves as a form of vision.

A. They do not have eyes but they have light- and touch-sensitive organs (receptor cells). These cells help them sense differences in light intensity and to feel vibrations in the ground. A. Earthworms breathe through their skin.read more >>
