This partial mandible from the mouth of a Rorqual whale or a baleen whale is broken in two pieces. These whales are the largest animals on Earth. The term baleen derives from the strong, flexible, and long protein plates in the whale's mouth. These plates strain large volumes of water to retrieve food such as krill. The rows of compact baleen are attached to the upper jaw only and allow the lower jaw to swing open to approximately 90 degrees. Each piece is about 3.75cm thick and measures roughly 28cm x 5.75cm and 19.5cm x 7cm.
