There were two errors published in J. Exp. Biol. 212, 1716-1730.
In Table 1, the units for `Total ammonia' are incorrectly listed as μmol l–1 instead of mmol l–1, although the units referred to in the text of the article are correct.
Also in Table 1, the mangrove killifish is incorrectly referred to by its previous genus, Rivulus marmoratus. It should have been listed as Kryptolebias marmoratus, as used in the rest of the article.
The authors apologise sincerely to readers for these errors.
