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. Remote requires one 9-volt battery. Each color has a different remote frequency so multiple sharks can be used simultaneously. Ages 8 and up. The manufacturer has confirmed that this item meets all U.S. Federal toy safety standards, including safety standards for lead.
