Summary1.The posterior sublingual gland of the little file snake (Acrochordus grnulatus) is a salt gland. It secretes a fluid as concentrated as 600 mM Na and 20 mM K. Cl is the anion; mean values during active secretion are 432–553 mM.2.The location and structure of the little file snake salt gland are extremely similar to those of sea snake salt glands. This similarity is believed to have originated independently by convergent evolution since the file snakes (Acrochordidae) are not closely… Expand

Dehydration and Drinking Behavior of the Marine File Snake Acrochordus granulatus*
TLDR
The results support a growing conclusion that diverse taxa of marine snakes require environmental sources of freshwater to maintain water balance, contrary to earlier belief. Expand
Morphological and biochemical evidence for the evolution of salt glands in snakes.

TLDR
It is proposed that the evolution of the snake salt gland by co-option of an existing gland involved at least two steps: an increase in the abundance of NKA and NKCC in the basolateral membranes of the secretory epithelia, and loss of AQP3/mucus secretion from these epithelium. Expand
Sea snake skin: Permeable to water but not to sodium
TLDR
The importance of the skin as a permeability barrier suggests that the frequent skin shedding of sea snakes may be related to maintenance of low water permeability as well as to prevention of growth by marine fouling organisms. Expand
Comparison of the osmoregulatory capabilities among three amphibious sea snakes (Laticauda spp.) in Taiwan
TLDR
This study suggests that the NKA activity of the sublingual gland is associated with salt excretion, and the three species possess different osmoregulatory strategies which are associated with their habitat affinities. Expand
Sea Snakes (Laticauda spp.) Require Fresh Drinking Water: Implication for the Distribution and Persistence of Populations
TLDR
It is reported that three species of sea snake actually dehydrate in marine environments, and it is shown that Laticauda spp. Expand
The unusual biology of marine file snakes with a perspective for the conservation of Acrochordus granulatus
Biodiversity and the function of tropical shallow-water marine environments are threatened by numerous anthropogenic factors, especially climate change, overharvesting of resources, and destructionExpand
Hypernatremia in Dice Snakes (Natrix tessellata) from a Coastal Population: Implications for Osmoregulation in Marine Snake Prototypes
TLDR
Assessment of natremia of free-ranging Dice snakes from a coastal population in Bulgaria suggests that snake species display a concomitant tolerance toward hypernatremia, even in species lacking salt glands, and may well have preceded the evolution of salt glands. Expand
Sodium and water budgets of the fasted estuarine crocodile,Crocodylus porosus, in sea water
  • L. Taplin

  • Journal of Comparative Physiology B
  • 2004
TLDR
Quantitative sodium and water budgets have been constructed for the estuarine crocodile,Crocodylus porosus, unfed in sea water in the laboratory and there is no evidence to suggest that C. Porosus feeds selectively on invertebrate prey of low Na or high water content despite the apparent selective advantage of minimizing water losses associated with extra-renal Na excretion. Expand
Salinity influences the distribution of marine snakes: Implications for evolutionary transitions to marine life
TLDR
The role of oceanic salinity as a proximate physiological challenge for snakes during the phylogenetic transition from the land to the sea is investigated and it is inferred that all four independent transitions from terrestrial to marine life in snakes may have occurred in the Indonesian Basin. Expand
Perspectives on the convergent evolution of tetrapod salt glands.
TLDR
This review synthesizes the available data regarding the distribution of salt glands across extant and extinct tetrapod lineages and the anatomical position of the salt gland in each taxon and develops hypotheses about the various factors that have influenced the convergent evolution of salt gland across taxa.

Sea Snakes: An Unusual Salt Gland under the Tongue
TLDR
The posterior sublingual gland of sea snakes is a salt gland that secretes a fluid surpassing seawater in sodium chloride concentration and the rate of electrolyte excretion from the larger gland is greater. Expand

TLDR
Data show that a powerful salt gland is present, emptying into the oral region of this sea snake, suggesting an osmotic control of gland secretion. Expand

TLDR
The rusty monitor salt gland has the ability to adjust the Na/K over a wide range and can excrete Na at a rate slightly above that of the estuarine diamondback terrapin and certain sea snakes. Expand

TLDR
Preliminary evidence provides little support for the concept that American and “salt water” crocodiles utilize salt glands as a major pathway of electrolyte excretion, although these crocodiles are fairly tolerant of exposure to sea water. Expand
Water Relationships in Natrix sipedon
TLDR
The snakes studied are Natrix sipedon confluens Blanchard, typically a fresh water race; and Natrix clarki, an inhabitant of Gulf Coast salt marshes, both of which maintain remarkably distinct morphological characters in areas outside the zone of intergradation. Expand

TLDR
A low-viscosity embedding medium based on ERL-4206 is recommended for use in electron microscopy and has a long pot life of several days and infiltrates readily because of its low viscosity. Expand
