This one goes with all the other interesting  Remote Control Toys we have featured earlier. This Radio Remote  controlled 2' long shark from Discovery channel swims like a real one and dives up to 9' deep with a propeller built into the shark's tail.

The remote control has  a range of 40'  and moves the shark left, right, up, foward, down or even reverse, and can be used underwater as well. The Remote Control Shark includes a battery and a battery charger. 

Pretty cool, but don't expect anyone to get scared. Available from here for US$ 79.95.
