Help us improve the site by taking our survey. It is thought that chemical detection is achieved on land when sensory epithelial cells detect chemicals as air passes through the sinuses and achieved in the water by the chemoreceptors lining the tongue. Crocodilians can achieve complex vocalizations by forcing exhaled air through a constriction by varying tensions in the muscles lining the glottis, and by expanding the throat via the hyoid apparatus, amplification can be achieved.

Philippine crocodiles lay their second clutch 4 to 6 months after the first, and can lay up to three clutches in a year. People kill these animals for their skins and meat, and to protect their livestock and their own safety. But the morphological, ecological and genetic proofs are not sufficient for declaring this animal neither as a distinct race, that is Crocodylus raninus, nor as subspecies or race of the Crocodylus mindorensis. Of the 24 species of crocodilian, 7 are currently listed as Critically Endangered, 4 as Vulnerable, 12 as Least Risk.

Several species of Asian crocodiles such as the Crocodylus mindorensis, the Crocodylus novaeguineae, the Crocodylus porosus and the Crocodylus siamensis independently from their size, have often a similar morphology which renders them difficult to distinguish, and this has led several zoological biologists to hypothesize their descending from a common progenitor. found in the oriental region of the world. : 306-321. 12 (1-2): 169-173 ; Meganathan, P.R.
