What is "ika-roa"

In Māori mythology, Ikaroa is the long fish that gave birth to all the stars in the Milky Way or the Mother Goddess of all the stars – ornaments of the Sky God. Ika-Roa is also an alternative name for the Milky Way.

Ika-roa was also called Mangōroa ("long shark") or Mangōroa i ata ("long shark in the early dawn").
