The Heavy jumper is a furry jumping spider that can be seen in mangroves. Like other jumping spiders (Family Salticidae), it does not build a web. Instead, it hunts on the move, attaching a silken line to a support before 'bungee jumping' onto suitable prey.

The Better to See You With! Jumping spiders have huge eyes. On the 'face' is a pair of enormous eyes with smaller ones around the head. These are not compound eyes like that of insects. Nevertheless, these eyes allow the spider to judge distance accurately.

Jumping babies: Male jumping spiders perform amusing rituals to entice a female to mate with them.
