The mugger crocodile is a Bangladeshi crocodile and it’s found beside river in Sundarban of Bangladesh. The mugger crocodile can be found some near country of Bangladesh, India, Sri Lanka, Pakistan, Nepal, the southern tip of Iran, and probably in Indo-China and at one point, even in Southern Iraq. It is one of the three crocodilians found in Bangladesh, the others being the gharial and the saltwater crocodile. It is a medium sized crocodile that mostly inhabits freshwater lakes, ponds, sluggish rivers, swamps and marshes. Males of the species may grow 4 m (13 ft) to 4.5 m (15 ft) in length, but rarely exceed 3.7 m (12 ft). As with other crocodilians, females are smaller. The mugger crocodile has the broadest snout of any extant crocodile, giving it an alligator-like appearance. It is a more heavily armored species with enlarged scutes around the neck. Adults are dark grey or brown, while hatchlings are tan colored.
The Bangladeshi Mugger Crocodile:
The Bangladeshi Mugger Crocodile is a skilled predator that preys on a variety of species. Like other crocodilians they are ambush hunters and wait for their prey to come close. They wait camouflaged in the murky waters to launch the attack in the suitable moment. They mostly prey on fish, reptiles, birds and mammals. Reproduction takes place in winter months. Females lay eggs in nests that are holes dug in the sand. Temperature during incubation is the determinant of sex in the young. The mugger crocodile possesses the size to be a serious threat to humans but are not as aggressive as some other species, such as the sympatric saltwater crocodiles. They are also observed to usually avoid areas with saltwater crocodiles. Muggers are fairly social species and tolerate their conspecifics during basking and feeding.
Characteristics of Bangladeshi Crocodile:
The mugger crocodile is very dangers when they hunt. It’s like a torpedo in water. Being a giant reptile, the mugger crocodile eats fish, other reptiles and small mammals, such as monkeys. 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. Large adults will sometimes prey on large mammals such as deer, including the 225-kg sambar deer, and the 450-kg domestic water buffalo. Mugger crocodiles have 19 upper teeth on each side; a snout that is 1⅓ to 1½ 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 Bangladeshi Mugger Crocodile can achieve speed of around 8 mph over a short distance in pursuit of prey. They can swim much faster than they can run—achieving speeds of 10 to 12 mph in short bursts—and can cruise at about 1 to 2 mph.
Crocodiles of World:
Crocodiles (subfamily Crocodylinae) or true crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodylinae, in which all its members are considered true crocodiles, is classified as a biological subfamily. A broader sense of the term crocodile, Crocodylidae that includes Tomistoma, is not used in this article. The term crocodile here applies only to the species within the subfamily of Crocodylinae. The term is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes Tomistoma, the alligators and caimans (family Alligatoridae), the gharials (family Gavialidae), and all other living and fossil Crocodylomorpha.
Although they appear to be similar to the untrained eye, crocodiles, alligators and the gharial belong to separate biological families. The gharial having a narrow snout is easier to distinguish, while morphological differences are more difficult to spot in crocodiles and alligators. The most obvious external differences are visible in the head with crocodiles having narrower and longer heads, with a more V-shaped than a U-shaped snout compared to alligators and caimans. Another obvious trait is the upper and lower jaws of the crocodiles are the same width, and teeth in the lower jaw fall along the edge or outside the upper jaw when the mouth is closed; therefore all teeth are visible unlike an alligator; which possesses small depressions in the upper jaw where the lower teeth fit into. Also when the crocodile's mouth is closed, the large fourth tooth in the lower jaw fits into a constriction in the upper jaw. For hard-to-distinguish specimens, the protruding tooth is the most reliable feature to define the family, the species belongs to. Crocodiles have more webbing on the toes of the hind feet and can better tolerate saltwater due to specialized salt glands for filtering out salt, which are present but non-functioning in alligators. Another trait that separates crocodiles from other crocodilians is their much higher levels of aggression.
Crocodile size, morphology, behavior and ecology somewhat differs between species. However, they have many similarities in these areas as well. All crocodiles are semiaquatic and tend to congregate in freshwater habitats such as rivers, lakes, wetlands and sometimes in brackish water and saltwater. They are carnivorous animals, feeding mostly on vertebrates such as fish, reptiles, birds and mammals, and sometimes on invertebrates such as molluscs and crustaceans, depending on species and age. All crocodiles are tropical species that unlike alligators, are very sensitive to cold. They first separated from other crocodilians during the Eocene epoch, about 55 million years ago. Many species are at the risk of extinction, some being classified as critically endangered.
Crocodile is a dangers animal in water without extra safety you don’t swim on water of Sundarban. It’s like a torpedo in water.
