def self.find_all(text)
  # Because scan doesn't support named captures, we have to use numbered capture groups.
  # Make sure to keep all groups you don't want to reference below as non-capturing groups.
  # Each name regex has a capture group (so as to avoid noise), so you don't see them here.
  # The order of the captures corresponds to the order of the fish names in the regex above.
