Urodela
Definition:
(n. pl.) An order of amphibians having the tail well developed and often long. It comprises the salamanders, tritons, and allied animals.

(5) In the pituitary of an Amphibian (Urodela), various cell types were localized by cytoimmunological techniques: corticotrophs located in a rostral zone near the median eminence, ventral orangeophilic cells secreting a prolactin-like hormone and erythrosinophilic cells in a more dorso-caudal situation secreting growth hormone.
(6) Analysis of the kinetics of carbon monoxide binding by hemoglobin from the tadpole of Xenopus laevis supports that model and suggests an explanation for the absence of an alkaline Bohr effect in many aquatic Anura and Urodela.
