Woodcut "portrait of the Hoga, a monstrous fish" from Des Monstres et prodiges by Ambroise Par矇, 1573. Des Monstres is filled with unsubstantiated accounts of sea devils, marine sows, and monstrous animals with human faces. With its extensive discussion of reproduction and illustrations of birth defects, the book invited accusations of pornography. The hoga or andura is an aquatic monster in the traditions and folklore of Mexico. The Hoga is described as being like a gigantic fish creature, with a head and ears like those of a pig, and extremely long barbs or thick whiskers round its mouth in which were great fangs. This creature amazingly had the ability to change color and could be red, green or yellow. Humans were afraid of the Hoga since it was reported to take vast fish and even land animals if they strayed too close to the water's edge.
