The smallest reproductively active male and female I. squamulosa measured 47 mm and 58 mm SVL, respectively. Males began ...
Secretory vesicle refilling and toxin production in Ollotis nebulifer (Coastal Plain Toad) and Anaxyrus speciosus (Texas Toad) following transcutaneous electrical stimulation of the parotoid glands.(Report)
Aug 01, 2008; ... Abstract--Parotoid glands in two species of toads, Ollotis nebulifer and Anaxyrus speciosus were expressed using transcutaneous electrical stimulation.
