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).
Bull Shark - Carcharhinus leucas
The bull shark, Carcharhinus leucas, also known as Zambezi shark or unofficially known as Zambi in Africa and Nicaragua shark in Nicaragua, is a shark common worldwide in warm, shallow waters along coasts and in rivers. The bull shark is well known for its unpredictable, often aggressive behavior. The Bull shark can thrive in both saltwater and freshwater and can travel far up rivers. They have even been known to travel as far up as Indiana in the Ohio River and Illinois in the Mississippi River, although there have been few recorded attacks. They are probably responsible for the majority of near-shore shark attacks, including many attacks attributed to other species. However, bull sharks are not true freshwater sharks (unlike the river sharks of the genus Glyphis). The name bull shark comes from the shark's stocky shapes, broad, flat snout and aggressive, unpredictable behavior. In India, the bull shark may be confused with the Sundarbans or Ganges shark. In Africa it is also commonly called the Zambezi River shark or just Zambi. Its wide range and diverse habitats result in many other local names, including Ganges River Shark, Fitzroy Creek Whaler, van Rooyen’s Shark, Lake Nicaragua Shark, river shark, freshwater whaler, estuary whaler, Swan River Whaler, cub shark, and shovelnose shark. Bull sharks are large and stout, with females being larger than males. Bull sharks are large and stout, with females being larger than males. The bull shark can be up to 81 cm (2.66 ft) in length at birth. Adult female bull sharks average 2.4 m (7.9 ft) long and typically weigh 130 kg (290 lb), whereas the slightly smaller adult male averages 2.25 m (7.4 ft) and 95 kg (210 lb). While a maximum size of 3.5 m (11 ft) is commonly reported, there is a questionable record of a female specimen of exactly 4 m (13 ft). The maximum recorded weight of a bull shark was 315 kg (690 lb) but may be larger. Bull sharks are wider than other requiem sharks of comparable length, and are grey on top and white below. The second dorsal fin is smaller than the first. Per the Discovery Channel and Animal Planet program Animal Face-Off, bull sharks have a bite force of up to 567 kilograms (1,250 lb). The bull shark's caudal fin is longer and lower than that of the larger sharks It also has a small snout. There is a lack of an interdorsal ridge. Bull sharks mate during late summer and early autumn, often in the brackish water of river mouths. After gestating for 12 months, a bull shark may give birth to four to ten live young. They are viviparous; they are born live and free-swimming. The young are about 70 cm (27.6 in) at birth and take 10 years to reach maturity. Coastal lagoons, river mouths, and other low-salinity estuaries are common nursery habitats.
