A Possible New Salt Gland in a Marine Homalopsid Snake (Cerberus rhynchops)
The dog-faced water snake, Cerberus rhynchops, appaiently has a small premaxillary salt gland, which is not homologous with previously known lachrymal (turtles), nasal (lizards) or posteriorExpand
Ultrastructure of pigment cells in wild type and color mutants of the Mexican axolotl
The defects in chromatophore development of the axanthic and melanoid mutants seem to occur prior to formation of prepigment organelles, and albino integument contains cells filled with granules identified as premelanosomes. Expand
The nasal gland of the Montpellier snake Malpolon monspessulanus: Fine structure, secretion composition, and a possible role in reduction of dermal water loss
A study was made of the structure and function of the enlarged lateral nasal gland of the Montpellier snake (Malpolon monspessulanus), which contains a complex mixture of fatty acids, proteins, and variable amounts of sodium and potassium. Expand
Interspecific differences in fluid concentration and secretion rate of sea snake salt glands.
Convergent evolution of sublingual salt glands in the marine file snake and the true sea snakes
The location and structure of the little file snake salt gland are extremely similar to those of sea snake salt glands, and this similarity is believed to have originated independently by convergent evolution since the file snakes are not closely related to the true sea snakes. Expand
The relation between plasma Na concentration and salt gland Na−K ATPase content in the diamondback terrapin and the yellow-bellied sea snake
The Na−K ATPase activity of the diamondback terrapin (Malaclemys) lachrymal salt gland increased with a rise in Na concentration of the plasma, and some terrapins kept in sea water for many months may not have fully active glands. Expand
Sea Snakes: An Unusual Salt Gland under the Tongue
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
Ion and water balance in normal and mutant fluid imbalanced (ff) embryos of the axolotl (Ambystoma mexicanum).
In normal axolotl embryos (10 or 20°C) Na influx, net Na uptake and water content increased greatly before hatching, but there were no cells in the gill similar to the Cl or “S” cell of fish gill. Expand
Evidence for the presence of nasal salt glands in the roadrunner and the Coturnix quail.
The characteristic fine structure and the high Na-KATPase content of the quail nasal gland suggest that it is a salt gland, which roadrunners were previously known to possess but quail were not. Expand
