The forelimb or pectoral flipper of the harbor seal has five digits of comparable length. This replica, cast from a real bone specimen, is perfect for teaching aquatic adaptation and locomotion. With real bone specimens requiring a permit to possess his replica is a perfect substitute. This filler assembly is a great companion to our replica harbor seal skull. For other aquatic mammal flipper assemblies and comparison, be sure to see our manatee and dolphin flippers.
