Sea-lion

Sea-lion refers to a legendary creature that has the head and upper body of a lion, but with webbed forelimbs and a fish tail. The creature appears most frequently as supporters, but also occur as crests and occasionally as charges. Sea-lions are frequently found in "sejant" or "sejant-erect" (sitting upright) attitudes, but may also be found "naiant" (horizontally, as if swimming) or "assurgeant" (issuing from the waves of the sea).
