This article is about spiders who like water and can even live in it.
The fishing spider can move across the surface of the water as easily as across a rock. It can chase insects on the water surface, or lure insects and small frogs within reach of attack by sitting quietly and vibrating its front legs to create a small ripple. The ripple on the surface of the water entices the prey to swim close enough for the spider to dive down and catch it.
The water spider lives its entire life underwater. In order to breathe, it builds an underwater “house”- a bell-shaped silk pocket that it fills with air bubbles from the surface. The air pocket gives the spider a safe place to eat and sleep. Whenever the spider gets hungry, it swims away to hunt for food.
