; order Araneae, suborder Araneomorphae)
Family of spiders whose common name refers to their sideways-running gait when disturbed. They have legs with only two claws, the anterior legs being held laterally, not forward. They are broad-bodied, and generally the first two pairs of legs are more robust than the posterior two pairs. The spinnerets are small and inconspicuous. Some species live on bark, and all have a potent arthropod venom. Misumena vatia can change its colour to match the yellow or white flowers on which it sits in wait for prey.
