GENERAL HISTOLOGY

Detailed explanation-1: -Eye: The common sea star has five eye spots on the tip of each of its five rays. These eye spots can see shadows and light.

Detailed explanation-2: -The arms are covered with pincerlike organs and suckers that allow the animal to slowly creep along the ocean floor. Light-sensitive eyespots on the tips of the arms help the sea star find food.

Detailed explanation-3: -Sea stars have an eye spot at the end of each arm. This means that a five-armed sea star has five eyes, while the 40-armed sun star has 40 eyes. Each sea star eye is very simple and looks like a red spot.

Detailed explanation-4: -Sea stars don’t have brains, but they do have eye “spots” at the end of their rays that help them detect light. They also have a water vascular system that supplies the water pressure needed to operate their tube feet.

Detailed explanation-5: -Most starfish possess a crude eye at the tip of each arm. These compound eyes contain multiple lenses called ommatidia, each creating one pixel of the total image the animal sees.
