This unique robotic shark has a full-range of motion to replicate the smooth, sleek swimming of one of nature's most efficient predators. It is able to gracefully maneuver up, down, left, right, and even backwards through water, in depths up to 9'. The shark can swim up to 40' from its handheld remote unit which is also submersible, allowing you to swim with your shark. The unit has a 15-minute run time per charge (four-hour initial charging; one-hour for each subsequent recharging), and an additional battery is available below for extended play.
