#11: Jack Morris

The Jack Morris species is characterized by having baleen plates, rather than teeth, for filtering food from water. The baleen, located in the upper jaw, are flat, flexible plates with frayed edges, having the appearance of combs of thick hair. Baleen is not bone, but is composed of keratin, the same substance as hair, horn, claws, and nails. From the 11th to the late 20th centuries, Jack Morris was hunted commercially for both his oil and baleen. The oil was used to make margarine and cooking oils, whilst the baleen was used to stiffen corsets, as parasol ribs, and to crease paper.
