Do Cockroaches Have Eyes?
WouterMany people wonder, “Do cockroaches have eyes?” The answer is yes! The eyes of a cockroach are complex and have a 360-degree field of vision. This allows them to see objects up to a mile away. They also have an incredibly high spatial-resolution, which helps them see objects at a glance. Unlike humans, cockroaches do not have smell or hear, so their eyes are their only senses.
Cockroaches are an enormous detachment of insects that are found throughout the world. Their vision is based on organs of touch, but some have visual organs on their heads. Some have two pairs of eyes on the front of their heads. These are what help cockroaches to see in the dark. The eyes of cockroaches are also called “facet eyes.”
In addition to their eyes, cockroaches have other organs. Their pheromones allow them to communicate with other roaches. Their antennas are made up of 50 small antennas that open in a straight line from their head to their abdomen. If they detect another cockroach, they will advance toward it, which is very useful for finding a mate.
Cockroaches do not have hearts, but they do have nerve cells, though these do not produce any feelings of pain. They also have a long dorsal vessel for carrying hemolymph throughout their body. Cockroaches also have compound eyes that have hundreds of lenses. Each lens has a specific task.
