Zips, Curves and Glides through the water. No batteries or winding required! Just a flick of the wrist sends this 8 inch diving pool toy shark through the pool. Toy Shark swims up to 40 feet underwater! Play catch underwater, target practice, or drop it in the water and watch it dive to the bottom, rise to the top and glide across the surface. Great swimming pool toy from Swimways pool toys...The Dive & Glide Shark!
