Alligators/Caiman: 2 subfamilies =
Subfamily Diplocynodontinae (alligators):

Genus Alligator has 4 extinct species and 2 living: (a. mississippiensis) American Alligator and (a. sinensis) the Chinese Alligator.
*Amiercan's range is southern U.S. and the Chinese lives in the Yangtze river in China.
Subfamily Caimaninae (caiman):

There are 5living species of caiman:Cuvier's Dwarf, Smooth-fronted, yacare, broad-snouted, black, and spectacled (which has two subspecies)
*Caiman are found in central and south america.
Crocodiles:
one extinct species in the subfamily Mekosuchinae
the genus Euthecodon of the subfamily Crocodyliane is extinct
13 living species in 2 genra in the subfamily Crocodyliane includind animals like the nile croc, slender-snouted, freshies, philippine, saltwater, cuban, and Siamese crocodiles.
*Crocodiles live throughout the tropics in Africa, Asia, the Americas (Mexico and south with the exception of a very small population in Florida), and Australia.
Gharial (Family Crocodylidae; subfamily Tomistominae): 9 extinct genra, one living = the False or Malayan gharial

Don't hold me to this 100%, but i'm pretty darn close. The only problems in the numbers should arise from disputes in dna research.
Hope this helps.

Alligators are North American species. Related species like Caimans live in South America.
Crocodiles are only found in Africa, Asia and Australia.
I couldn't tell you exactly how many species there are in total, but a Google search should turn up the right answers for you pretty quickly.

in spite of the reality that the tail of the alligator is seen the top decrease, each and every of the beef of the alligator is appropriate for eating. From kabobs to scampi, crocodiles and alligators are suitable for eating. they're very primary in Australia!

there are only two species of alligator in the world, american alligators and chinese alligators.
there are 23 other types of crocodilian (including caimans and gavials) that occur worldwide in tropical areas.
Caimans are exclusive to south and central America.
Gavials are from India.
Crocodiles are from everywhere else.
