This 20" animal puppet has a movable mouth that is accessed from the back of the head. Recommended ages 3+ for ease of use. An octopus has two eyes and four pairs of arms, a hard beak, with its mouth at the center point of the arms. An octopus has no internal or external skeleton allowing it to squeeze through tight places. Octopuses are among the most intelligent and behaviorally flexible of all invertebrates. Octopuses inhabit many diverse regions of the ocean, including coral reefs, pelagic waters, and the ocean floor. They have numerous strategies for defending themselves against predators, including the expulsion of ink, the use of camouflage and deimatic displays, their ability to jet quickly through the water, and their ability to hide. An octopus trails its eight arms behind it as it swims. All octopuses are venomous, but only one group, the blue-ringed octopus, is known to be deadly to humans.
