A frog's ear drum works in very much the same way as does a human eardrum. It is a membrane that is stretched across a ring of cartilage like a snare drum that vibrates. Crossing the middle ear chamber there is an ossicle called the columella that is connected to the tympanum, and another ossicle, the operculum, that connects this to the oval ...
An example of a frog that possesses a larynx is the túngara frog. While the larynx is the main sound producing organ in túngara frogs, it serves a higher significance due to its contribution to mating call, which consist of two components: 'whine' and 'chuck'. [ 26 ]
Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [ 1 ] (the evolution of species). The science began in the classical era , continuing in the early modern period with work by Pierre Belon who noted the similarities of the skeletons ...
The frog's skin is green on top, but the skin on the glass frog's stomach is just as translucent as its name suggests. You can even see its organs through the skin, especially its heart, liver ...
The kidney of the frog is an opisthonephros. The kidneys are seen as two elongated, red organs in this image. The opisthonephros is the functional adult kidney in lampreys (cyclostomes), most fishes, and amphibians. [1] It is formed from the extended mesonephros along with tubules from the posterior nephric ridge. [2]
Snakes use this organ to sense prey, sticking their tongue out to gather scents and touching it to the opening of the organ when the tongue is retracted. [24] The organ is well developed in strepsirrhine primates such as lemurs and lorises, [25] developed to varying degrees in New World monkeys, and underdeveloped in Old World monkeys and apes ...
A Brief Biology Breakdown. Here’s what scientists do know: The ovaries are oblong glands each about the size of a kiwi. They’re responsible for the production and secretion of at least two ...
Some frogs such as the wood frog, moor frog, or spring peeper can even survive being frozen. Ice crystals form under the skin and in the body cavity but the essential organs are protected from freezing by a high concentration of glucose.
