9. Torpedo Ray
The three animals listed above all used their razor sharp teeth to kill, while the next three rely more on shock, stealth and speed. The torpedo ray looks like a stealth bomber but uses electric shocks as its weapon. It is one of 14 ray species that deliver such shocks and its power comes from a disk in the middle of its body. It traps fish beneath itself, folding its wings down around its victim and issuing a strong shock that at least stuns and normally kills its prey. The torpedo ray hunts in shallow waters, where divers are often present, and if alarmed can deliver a 50 volt shock, which is why many unexplained drownings are thought to be due to this fish. The current from the torpedo ray can cause cardiac arrest in people, and potentially death.
