This water spider has eight legs, no wings and a body which is divided into two sections. The similar water strider (see water strider) has six legs and wings. The water spider captures its food by running it down with its hairy legs. After catching it the spider bites it and injects a poison that dissolves the body. The spider then sucks out its body juices - a type of "animal slurpy." When it takes a rare trip below water it carries a bubble of air along like a scuba diver does. The spider's favorite foods are insects, small fish and tadpoles. Don't worry, they are too small to hurt you. Read more about spiders.
