Do Spiders Have Antennae?
WouterSpiders are part of the arachnid family. They have eight legs and a head. Their body is divided into two sections – the cephalothorax and the abdomen. Some spiders have hairs on their bodies as well.
While spiders do not have antennae, they do have other sense organs. They are able to pick up vibrations along web lines and the impact of their prey. They can also sense vibrations in the air around them. It is believed that some spiders have excellent vision.
Some species of spiders can see in color. Jumping spiders are known for their good vision. However, some arachnids lack eyes and have only simple light and dark-receptors. In addition, some species of spiders have more than eight eyes.
Cockroaches have two antennae, which they use to touch, feel and locate food. Grasshoppers have two antennae as well. Beetles have a long, flexible antenna on their head. Ants and flies have elbowed feelers that they use for sensing.
Other insects have antennae as well. These are used to detect surfaces and the presence of odors. The antennae help the insect identify its surroundings and the temperature. This helps the animal to defend itself from predators.
Spiders have hairs, which are essential for their survival. They have about 2400 hairs on each leg. When a spider needs to find a way to move, the hairs help it stick to its target. They also help the spider recognize the shape of its surroundings.
