Some rays have kidney-shaped organs on each side of their backbone. When touched, or while hunting pray, the rays body can discharge an electric currant that can reach 220 volts! Electric rays move slowly and usually lie in sand or mud.
They stun prey such as small fish, crabs, and worms. The electric current passes through the water, and the human victim of an intense shock may be knocked out, or lose the use of their limbs and risk drowning.
Spiders inject venom into their pray through hollow fangs. The venom kills small victims. It also breaks down their body tissues into liquid, so the spider can suck them up.
The Blue-ringed Octopus, the deadliest octopus in the world is found along Austrailas rocky shorelines.
