The kidneys of snakes are elongated, cylindrical [53] [50] and lobulated. [52] Turtles and some lizards have urinary bladder [50] that opens into the cloaca [54] but snakes and crocodiles do not have it. [50] Compared with the metanephros of birds and mammals, the metanephros of reptiles is simpler in structure. [21]
When slightly squeezed the frogs releases it stored water from its skin pockets and bladder. This water is safe to be consumed and Indigenous Australians would dig the frogs from their burrows and then drink the fresh water they released. [13] [5] The frog is then released with no direct harm caused to the amphibian. [8]

It has acquired a number of popular nicknames, including hippo frog , [ 3 ] Freddy Krueger frog , [ 3 ] and escuerzo de agua .
The world's largest frog is the goliath frog of West Africa—it can grow to 15 inches (38 centimeters) and weigh up to 7 pounds (3.2 kilograms). One of the smallest is the Cuban tree toad, which ...
Their kidneys (metanephros) and large intestines are also well-suited to water retention. Most mammals do not lay eggs, but corresponding structures develop inside the placenta. The ancestors of true amniotes, such as Casineria kiddi, which lived about 340 million years ago, evolved from amphibian reptiliomorphs and resembled small lizards.
Frogs have glandular skin, with secretions ranging from distasteful to toxic. Their skin varies in colour from well-camouflaged dappled brown, grey and green to vivid patterns of bright red or yellow and black to show toxicity and ward off predators. Adult frogs live in fresh water and on dry land; some species are adapted for living ...
Swim Bladder Disease: Common in fish like goldfish and bettas, swim bladder issues can make it difficult for them to swim properly. Treatment costs are generally minimal, around $50 to $100 for ...
Below this are a number of small glands secreting components of the seminal fluid. The final portion of the duct also receives ducts from the kidneys in most species. [21] In amniotes (mammals, birds, and reptiles), the archinephric duct has become a true vas deferens, and is used only for conducting sperm, never urine. As in cartilaginous fish ...
