The ypotryll is a legendary creature featured in heraldry. It is a type of chimera with the tusked head of a boar, humped body of a camel, legs and hooves of an ox or goat and tail of a serpent. It appears in Fenn's Book of Badges of c.1470 as the badge of John Tiptoft, 1st Earl of Worcester.
Its name probably derives from the Greek "hippo-", horse (cf. Middle English "ypotame", hippopotamus).
