alligator
Synonym discussion
Sense: noun/1
Alligators and crocodiles are often confused, but several features set them apart. An alligator has a wide, U-shaped snout, while a crocodile's snout is narrower and V-shaped. When an alligator closes its mouth, its lower teeth are mostly hidden; a crocodile's lower teeth remain visible on both sides of its upper jaw. Alligators prefer freshwater habitats such as rivers, lakes, and swamps, and are found only in the southeastern United States and eastern China. Crocodiles tolerate saltwater better and live in tropical regions across Africa, Asia, the Americas, and Australia. Caimans are smaller relatives of alligators, found in Central and South America; they have a more bony ridge between their eyes. For example: 'The tour guide pointed out a sunbathing alligator in the Florida swamp, then later showed us a saltwater crocodile near the coast.'

Etymology
The word 'alligator' entered English in the 16th century from the Spanish phrase 'el lagarto', meaning 'the lizard'. Spanish explorers and settlers in the Americas used this term for the large reptile they encountered in Florida and nearby regions. Over time, 'el lagarto' was Anglicised into 'alligator'. The scientific name 'Alligator mississippiensis' reflects the Mississippi River region where the American species is common.
