13 



Figure 6. — A small adult female sea otter. White dots mark the umbilicus 

 and mammae. The relatively short, flattened tail of nearly uniform width 

 throughout its length, broadly flattened and webbed hind feet, and elongate 

 body are obvious characteristics which differentiate the sea otter from the 

 river otter. (Specimen KWK 61-2 [Susie], weight in life 40 lb. [18. 1 kg.], 

 length 127 cm. [50 in.]. Captured 4 September 1955, Amchitka Island, died 

 27 October 1961 in Seattle zoo.) (KWK 61-42-16)
