It is shown that the Australian lungfish (Neoceratodus forsteri) synthesizes ascorbic acid in its kidney, suggesting that ascorbic acid synthesis started before the origin of the tetrapods.

We snapfroze the tissue immediately after dissection in liquid nitrogen and later transferred it to a −70°C freezer where it was stored before being assayed; all tissue was assayed within a month of collection.
