A king of Tara named Aed owned one of these animals that kept him  invincible. Scottish folklore claims that an animal of this sort was killed by a  witch and its rib-bone was turned into a whale rib. In addition to Glas  Ghaibhleann, a brown colored one of these animals was slain by Guy of  Warwick. In Hindu mythology, the four directions are guarded by four of these  animals named Saurabhi, Harhsika, Subhadra and Dhenu. A paradise full of  these animals is named Goloka. This type of animal was the daughter of  Vasistha and was named Nandini. Another one of these animals licked salt to  produce Buri. Including Audhumla, for 10 points, name these animals with  udders.
