Patagonian opossum regions has led the Patagonian opossum to feed on mainly birds and mice. One specimen of Patagonian opossum was caught using a dead bird as bait; this led some researchers to believe that the Patagonian opossum lives totally on birds.

This has created some confusion as there is a genuine "icefish" ("Champsocephalus gunnari") caught in subantarctic waters, which does not resemble toothfish in any way. Patagonian toothfish spawn in deep water (around 1,000m) during the austral winter, producing pelagic eggs and larvae. Larvae switch to a demersal habitat at
