The name "pangolin" comes from the Malay word pengguling meaning "one who rolls up" [22] from guling or giling "to roll"; it was used for the Sunda pangolin (Manis javanica). [23] However, the modern name is tenggiling. In Javanese, it is terenggiling; [23] and in the Philippine languages, it is goling, tanggiling, or balintong (with the same ...
The word amphibian is derived from the Ancient Greek term ἀμφίβιος (amphíbios), which means 'both kinds of life', ἀμφί meaning 'of both kinds' and βίος meaning 'life'. The term was initially used as a general adjective for animals that could live on land or in water, including seals and otters. [8]
[17] [18] Unlike other modern amphibians (frogs and salamanders) the skull is compact and solid, with few large openings between plate-like cranial bones. The snout is pointed and bullet-shaped, used to force their way through soil or mud. In most species the mouth is recessed under the head, so that the snout overhangs the mouth. [10]
They lack external hind limbs and are the only amphisbaenians with well-developed fossorial front limbs, which each include five claws. [3] They have a short tail that does not regenerate if lost. They use their blunt head for burrowing by ramming it into the soil, and usually prey on arthropods.
The hairy frog is also notable in possessing retractable "claws", which it may project through the skin, apparently by intentionally breaking the bones of the toe. [5] These are not true claws, as they are made of bone, not keratin. In addition, there is a small bony nodule nestled in the tissue just beyond the frog's fingertip.
The only amphibians to bear claws are the African clawed frogs. Claws evolved separately in the amphibian and amniote (reptiliomorph) line. [12] However, the hairy frog has claw analogues on its feet; the frog intentionally dislocates the tips of its fingers to unsheathe the sharp points of its last phalanges.
This is an index to the amphibians found in India. The amphibians of India show a high level of endemism. [1] This list is based largely on Darrel Frost (2006) [2] and includes common names from older books and journals. [3] [4] [5] Some Indian frogs
