The Underwater Treasures Birdman Skull is one of the more uncommon decorations you can add to your aquarium set up. The piece itself features a realistic human skull, complete with exposed teeth and sunken eyes, and sits inside the beak of a large eagle. The eagles head features individual carved and painted feathers, offering a complex arrangement that offer the shape and design of real bird feathers. The skull itself is hollow, with hollow eyes, allowing smaller fish and invertebrates to take refuge from more aggressive fish inside the cavity of the skull. This heavy ornament will not float or fall over, and is suitable for use in both freshwater and saltwater environments. 3.5" x 4.5" x 3.75"
