The significance of the salmon can be seen in many places. Gwyrhr questioned a series of wise animals, each one wiser than the previous, the oldest and wisest of all was the salmon of Llyn Llyw (Ford, 148-149).
Cúchulainn used the hero's salmon leap across the Pupils' Bridge to get Scáthach's stronghold in order to gain access to Scáthach's advanced knowledge of arms. To gain the secrets Cúchulainn had to use the hero's salmon leap to Scáthach herself in order to gain the secrets reserved for her family. Each leap in the land of sorcery brought Cúchulainn to greater knowledge.
