Abstract The Pacific hagfish (Eptatretus stoutii) has an exceptional ability to both withstand
and recover from exposure to high external ammonia (HEA). This tolerance is likely due to …

Aim Pacific hagfish are exceptionally tolerant to high environmental ammonia (HEA). Here,
we elucidated a cellular mechanism that enables hagfish to actively excrete ammonia …

Hagfish consume carrion, potentially exposing them to hypoxia, hypercapnia, and high
environmental ammonia (HEA). We investigated branchial and cutaneous ammonia …

Ammonia is an unusual toxicant in that it is produced by, as well as being poisonous to,
animals. In aqueous solution ammonia has two species, NH 3 and NH 4+, total ammonia is …

In teleosts, a branchial metabolon links ammonia excretion to Na+ uptake via Rh
glycoproteins and other transporters. Ureotelic elasmobranchs are thought to have low …

The swamp eel Monopterus albus lives in muddy ponds, swamps, canals, and rice fields in
the tropics. It encounters high concentrations of environmental ammonia (HEA) during dry …

The swamp eel Monopterus albus inhabits muddy ponds, swamps, canals and rice fields,
where it can burrow within the moist earth during the dry summer season, thus surviving for …

The aim of this study was to elucidate if the mudskipper Periophthalmodon schlosseri, in
relation to its capability to survive on land, has acquired a greater capacity to detoxify …

For the first time in a marine teleost (the long-horned sculpin; Myoxocephalus
octodecimspinosus), the maintenance of blood pH,,[HCO3−] and the net movements of …

Nitrogen (N) appears to be a limiting dietary resource for elasmobranchs, required not only
for protein growth but also for urea-based osmoregulation. Building on recent evidence that …
