Abstract The habit of gastric brooding is a form of parental care unique in the animal kingdom. Restrained individuals may release young from the stomach by a process of propulsive vomiting, but in the natural state and that documented here, the mother is passive, and the babies emerge from her mouth at intervals over a period of several days. 
Inhibition of gastric acid secretion in the gastric brooding frog, Rheobatrachus silus.
TLDR
The female gastric brooding frog Rheobatrachus silus may have developed a mechanism whereby prostaglandin secreted by the larvae inhibits acid secretion in the stomach of the female until the larvae have completed development and emerged as juvenile frogs by way of theFemale's mouth. Expand
Converting a stomach to a uterus: The microscopic structure of the stomach of the gastric brooding frog Rheobatrachus silus
TLDR
These findings suggest that the eggs, tadpoles, and juvenile frogs release a substance, or substances, that inhibit acid secretion immediately after the eggs are ingested and that persist throughout brooding. Expand
Gastric acid secretion in the toad Bufo marinus with the description of a new technique for in vivo monitoring.
TLDR
A technique for the implantation of a pH electrode into the stomach of the toad, Bufo marinus, permits continuous monitoring of gastric pH for extended periods and results from continuous monitoring and from acute measurements of Gastric pH are compared in fasting and fed toads. Expand
Changes in the organization and ultrastructure of smooth muscle cells in the stomach of the gastric brooding frog, Rheobatrachus silus, during brooding
TLDR
It is suggested that during gastric incubation of the young, smooth muscle cells become at least partially dissociated from their surrounding connective tissue matrix, allowing maximal distension of the stomach wall. Expand

The Physiology, Morphology, and Ontogeny of Emetic Behavior in Anuran Amphibians
TLDR
The data suggest that the sacroiliac musculoskeletal complex of frogs is as important to the elevation of abdominal pressure during actions such as emesis, oviposition, micturition, etc., as it is to adult locomotion. Expand
Evolution of Oviductal Gestation in Amphibians
TLDR
The restrictive definitions mentioned above for vivipar- ity and ovoviviparity are used in this discussion, since the "grey areas" of nutrient uptake found in placental reptiles, and in fishes, seem not to obtain in amphibians. Expand
The Evolution of Viviparity in Fishes, Amphibians and Reptiles: An Endocrine Approach
TLDR
Historically, few studies have examined the physiological adaptations required for the change from oviparity to viviparity in vertebrate groups. Expand

Live‐bearing has evolved in all three orders of amphibians—frogs, salamanders, and caecilians. Developing young may be either yolk dependent, or maternal nutrients may be supplied after yolk isExpand
