The Mugger Crocodile (Crocodylus palustris) (literally "Crocodile of the marsh"), also called the Iranian, Marsh, or Persian Crocodile (in Persian گاندو Gandu), is found throughout the Indian subcontinent and the surrounding countries (India, Pakistan). In Pakistan's coastal regions of the Makran and delta marshlands of Sindh it is known as the Indus Crocodile, although they do exist in parts of Bangladesh, and parts of Nepal and Iran. The name "Mugger" is a corruption of the Hindi word magar which means "water monster" in the Hindi language.^[1]

Description

Mugger crocodiles have 19 upper teeth on each side; a snout that is 1 1/3 to 1 1/2 as long as broad at the base; a rough head but without any ridges; mandibular symphysis extending to the level of the fourth or fifth tooth; pre-maxillo-maxillary suture, on the palate, transverse, nearly straight, or curved forwards; and nasal bones separating the pnemaxillaries above. Four large nuchals forming a square, with a smaller one on each side; two pairs of smaller nuchals on a transverse series behind the occiput. Dorsal shield well separated from the nuchal, the scutes usually in 4, rarely in 6, longitudinal series, those of the two median usually considerably broader than long; 16 or 17 transverse series. Scales on limbs keeled. Fingers webbed at the base; outer toes extensively webbed. A serrated fringe on the outer edge of the leg. Adult blackish olive above: young pale olive, dotted and spotted with black. The largest specimen in the British Museum measures 12 feet, but individuals are said to grow much larger.^[2]

Distribution

The Mugger crocodile can be found in India, Bangladesh, Sri Lanka, Pakistan, Nepal, the southern tip of Iran and probably in Indo-China. The Mugger is the only crocodilian found in Iran and Pakistan. This crocodile is the most common and widespread of the three species of crocodiles in India, far out numbering the much larger saltwater crocodile within the country (and most likely within neighboring countries).

In the 1980's the largest population of wild Crocodiles in Tamil Nadu, South India lived in the Amaravathi Reservoir, and in the Chinnar, Thennar and Pambar rivers that drain into it. Their total population here was estimated to be 60 adults and 37 sub-adults. The Amaravati Sagar Crocodile Farm, Established there in 1975, is the largest Crocodile nursery in India. Eggs are collected from wild nests along the perimeter of the reservoir to be hatched and reared at the Farm. There were up to 430 animals maintained in captivity at one time. Hudreds of adult crocodiles have been reintroduced from here into the wild.^[3]

Habitat

Mainly a freshwater species, the Mugger crocodile is found in lakes, rivers and marshes. Muggers prefer slow-moving, shallower bodies of water rather than, fast-flowing, deep areas. Also known to thrive in man-made reservoirs and irrigation canals. Although it prefers freshwater, it has some tolerance to saltwater therefore is occasionally reported from saltwater lagoons. It is sympatric with the Gharial (Gavialis gangeticus) in some areas of India and with the Saltwater Crocodile (Crocodylus Porosus) in other areas, but separated by habitat most of the time. It is adapted to terrestrial life like its cousin, the Cuban Crocodile, more than most crocodilians. It is known to be more mobile on land, can migrate considerable distances over land in search of a more suitable habitat. It can chase prey on land for short distances. They are also known to dig burrows as shelters during the dry seaons.

Diet

Being a large carnivorous reptile, it eats fish, other reptiles and small and large mammals. In fact, most vertebrates that approach to drink are potential prey, and may suffer being seized and dragged into the water to be drowned and devoured at leisure. Attacks on humans are very rare, but not unheard of, as a child was killed by a Mugger crocodile in Iran during early 2006.
