Polypedates maculatus, the Indian tree frog, [1] or Chunam tree frog, is a common species of tree frog found in South Asia. It was described by John Edward Gray in 1830. [2] Although now considered as a separate species again, for a time, the Himalayan tree frog was considered as a subspecies of the Indian tree frog (as P. m. himalayensis). [1]
Rana (derived from Latin rana, meaning 'frog') is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs.Members of this genus are found through much of Eurasia and western North America.
Hoplobatrachus tigerinus, commonly known as the Indian bullfrog, is a large species of fork-tongued frog found in South and Southeast Asia. A relatively large frog, it is normally green in color, although physiological traits vary between populations. Sexual dimorphism exists between males and females.
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 ...
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
The amount of entrained water the frog can ingest is related to its ability to actively increase its body volume. The frog's buccopharyngeal cavity (the cavity connecting the mouth and the pharynx) is very distensible and can expand substantially. It uses its entire trunk to rapidly enlarge the cavity, which expands into the lower end of the trunk.
The European tree frog (Hyla arborea) is common in the middle and south of Europe, and its range extends into Asia and North Africa. North America has many species of the family Hylidae, including the gray tree frog ( Hyla versicolor ) and the American green tree frog ( H. cinerea ).
The frog's coloration is representative of flash coloration. Flash coloration describes when an organism displays certain colors at rest compared to when in motion. [8] In the red-eyed tree frog's case, the frog's startling red eyes are hidden when its eyes are closed allowing it to blend in with leaves.
