Hormone-dependent dissociation of blood flow and secretion rate in the lingual salt glands of the estuarine crocodile, Crocodylus porosus

It is evident from this study that blood flow to, and secretion rate from, the lingual salt glands of C. porosus are regulated independently; indeed, it is apparent that maximal secretion from the salt glands may not require maximal blood flow.

Osteological and vascular morphology and electrolyte homeostasis of sea turtles.

A significantly larger cross-section in the foramen stapedio-temporalis of sea turtles than other freshwater/terrestrial turtles is confirmed, which may indicate marine adaptation of turtles and are applicable to both fossil and osteological specimens.

Mangroves as Feeding and Breeding Grounds

Cranial anatomy of the Galápagos marine iguana Amblyrhynchus cristatus (Squamata: Iguanidae)

The first ever description of the skull, mandible, and hyoid of Amblyrhynchus is provided, able to identify several autapomorphic features that distinguish the marine iguana from all other iguanids.

Active airflow of the paranasal sinuses in extinct crocodyliforms: Evidence from a natural cast of the thalattosuchian Dakosaurus andiniensis

A stepwise evolutionary scenario of Thalattosuchia is proposed, implying changes in the preorbital region (and orbit orientation) where the internalized antorbital sinus via its subsidiary diverticulum was co-opted for helping nasal glands drainage.

Osmoregulatory ability predicts geographical range size in marine amniotes

Analysis of data on 62 species confirms that more-widely distributed taxa encounter habitats with a wider range of salinities, and that they have higher osmoregulatory ability as determined by sodium concentrations in fluids expelled from salt-excreting organs.

The role of selection in the evolution of marine turtles mitogenomes

The accelerated evolutionary rates found for sea turtles on COX2, ND1 and CYTB and the molecular footprints of positive selection found on ND4 and ND5 genes may be related to mitochondrial molecular adaptation to stress likely resulted from a more active lifestyle in sea turtles.



Handbook of Turtles

Two hundred million years ago the reptiles, newly arisen from an uncommonly doughty set of amphibians, were on the verge of great adventures. They bore the mark of destiny in the shape of impervious

Extrarenal salt excretion in birds.

Investigations on cormorants (Phalacrocorax auritus) gave no evidence to support the hypothesis that sea birds must drink sea water in order to cover their normal needs for water. When the birds we...

Nasal Salt Secretion in the Humboldt Penguin

It was found that in cormorants much salt may be excreted extra-renally in the form of a highly concentrated solution of sodium chloride, discharged from the nasal (salt) glands1.
