Yes, some species of sea stars have eye spots at the tips of their arms. These eye spots are simple photoreceptors that can detect changes in light levels and help the sea star navigate its environment.
Euglenoids, a group of protists within the Euglenophyta phylum, possess eye spots, or stigma, that help them detect light. These eye spots are typically located near the flagellum and allow euglenoids to sense light intensity, enabling them to move toward optimal light conditions for photosynthesis. This adaptation is crucial for their survival in varying aquatic environments.
Do you mean star? The nearest visible star is Alpha Centauri.
Fomalhaut appears to be a bright white star to the naked eye.
An Io Moth can scare away birds by flashing its bright eye spots located on its hindwings when threatened. The sudden appearance of these eye spots can startle or confuse predators, giving the moth a chance to escape.

Star fish don't have eye spots, or eyes, they depend on their skin to detect light.
Not all echinoderms have eye spots. While many echinoderms, such as starfish and some sea cucumbers, possess simple light-sensitive structures called eye spots, others do not. The presence and complexity of these eye spots can vary widely among different echinoderm species, reflecting their diverse adaptations to marine environments. Overall, eye spots are not a universal feature across all echinoderms.

Yes
Yellow spots on the eye are often caused by pingueculas. Pingueculas are noncancerous growths on the cornea and are thought to be caused by UV exposure.
conjunctivitis
Yes, they do
no
