False Gharial - Tomistoma schlegelii
The false gharial (Tomistoma schlegelii), also known as the Malayan gharial, or false gavial is a freshwater crocodile of the Crocodylidae family with a very thin and elongated snout. The signature feature of the species is its extremely long and slender snout, which is even slimmer than the snout of the Slender-snouted crocodile's and comparably as slender as that of the Gharial or the Freshwater crocodile. It is dark reddish-brown above with dark brown or black spots and cross-bands on the back and tail. Ventrals are grayish-white, with some lateral dark mottling. Juveniles are mottled with black on the sides of the jaws, body, and tail. The snout is smooth and unornamented, and 3 to 3.5 times the width at the base. All teeth are long and needle-like, interlocking on the insides of the jaws, and are individually socketed. The fingers are webbed at the base. Integumentary sensory organs are present on the head and body scalation. Scales behind the head are frequently a slightly enlarged single pair. Some individuals bear a number of adjoining small keeled scales. Scalation is divided medially by soft granular skin. Three transverse rows of two enlarged nuchal scales are continuous with the dorsal scales, which consist of 22 transverse rows of 6 to 8 scales, are broad at mid-body and extend onto the sides of the body. Nuchal and dorsal rows equals a total of 22 to 23 rows. It has 18 double crested caudal whorls and 17 single crest caudal whorls. The flanks have one or two longitudinal rows of six to eight very enlarged scales on each side. Adult males weigh 150 to 250 kg (330 to 550 lb), while females are about 3.2 m (10 ft) long and weigh an average of 90 kg (200 lb).
Largetooth Sawfish - Pristis microdon
The largetooth sawfish (Pristis microdon), also known as the Leichhardt's sawfish or freshwater sawfish, is a sawfish of the family Pristidae, found in shallow Indo-West Pacific oceans between latitudes 11° N and 39° S. As its relatives, it also enters freshwater. This critically endangered species reaches a length of up to 7 metres (23 ft). Reproduction is ovoviviparous. Considerable taxonomic confusion surrounds this species. It is part of the Pristis pristis species complex, which also includes P. perotteti. P. microdon has sometimes been considered synonymous with P. perotteti, and uncertainty exists over what species the scientific name P. microdon really belong to (the original description lacked a type locality). The largetooth sawfish is a heavy-bodied sawfish with a short massive saw which is broad-based, strongly tapering and with 14 to 22 very large teeth on each side - the space between the last two saw-teeth on the sides are less than twice the space between the first two teeth. The pectoral fins are high and angular, the first dorsal fin being mostly in front of the pelvic fins, and the caudal fin has a pronounced lower lobe.
