Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
A chytrid-killed frog Chytridiomycosis in Atelopus varius—two sporangia containing numerous zoospores are visible.. Chytridiomycosis (/ k aɪ ˌ t r ɪ d i ə m aɪ ˈ k oʊ s ɪ s / ky-TRID-ee-ə-my-KOH-sis) is an infectious disease in amphibians, caused by the chytrid fungi Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans.
Beelzebufo most likely was a predator whose expansive mouth allowed it to eat relatively large prey, perhaps even juvenile dinosaurs. [ 9 ] [ 10 ] Bite force measurements from a growth series of Cranwell's horned frog ( Ceratophrys cranwelli ), suggest that the bite force of a large Beelzebufo —skull width 15.4 cm (6.1 in)—may have been ...
Brevicipitidae or rain frogs is a small family of frogs found in eastern and southern Africa.As of 2020 contains 37 species in 5 genera. [1] [2] Formerly included as subfamily in Microhylidae (narrow-mouth frogs), phylogenetic research has indicated the brevicipitine frogs should be considered as a family with Hemisotidae (shovelnose frogs) as the most closely related sister taxon.
The parotoid gland (alternatively, paratoid gland) is an external skin gland on the back, neck, and shoulder of some frogs (especially toads), and salamanders. It can secrete a number of milky alkaloid substances (depending on the species) known collectively as bufotoxins , which act as neurotoxins to deter predation .
This only happened in fish-free lakes, because only those had enough frogs and enough genetic variation to evolve resistance. So in 2006 Knapp and other researchers set about to see if the frog ...

Fejervarya limnocharis is commonly sold as food in Southeast Asia, including Thailand, Laos, and Cambodia. In Cambodia, it is frequently collected for human consumption, along with Hoplobatrachus rugulosus, Glyphoglossus molossus, Kaloula pulchra, Duttaphrynus melanostictus, and Pelophylax lateralis (with P. lateralis found only north of the Mekong River in localities such as Snuol District ...
