The mugger crocodile

Fm Radio Link

The mugger crocodile is considered a medium-sized crocodilian, but has the broadest snout among living crocodilians.[4] It has a powerful tail and webbed feet. Its visual, hearing and smelling senses are acute.[2] Mugger hatchlings are pale olive with black spots. Adults are dark olive to grey or brown. The head is rough without any ridges and large scutes around the neck that is well separated from the back. Scutes usually form four, rarely six longitudinal series and 16 or 17 transverse series. The limbs have keeled scales with serrated fringes on outer edges, and outer toes are extensively webbed. The snout is slightly longer than broad with 19 upper teeth on each side. The symphysis of the lower jaw extends to the level of the fourth or fifth tooth. The premaxillary suture on the palate is nearly straight or curved forwards, and the nasal bones separate the premaxilla above.[9] Adult female muggers are 2 to 2.5 m (6 ft 7 in to 8 ft 2 in) on average, and male muggers 3 to 3.5 m (9 ft 10 in to 11 ft 6 in). They rarely grow up to 5 m (16 ft 5 in). The largest known muggers measured 5.63 m (18 ft 6 in).[2] The average size of adult mugger crocodiles in Manghopir Lake was estimated at 2.89 m (9 ft 6 in), with a weight of around 100 kg (220 lb).[10] One male mugger caught in Pakistan of about 3 m (9 ft 10 in) weighed 195 kg (430 lb).[11] The largest zoological specimen in the British Museum of Natural History measures 3.7 m (12 ft 2 in).[9]
