Own every animal of the family Alligatoridae.
Alligators and caimans live mostly in the fresh waters of the Americas. A single alligator species lives elsewhere, in China. Their snout is broader than that of crocodiles. With the mouth shut, the lower teeth stay hidden behind the upper jaw. Alligators build a nest of vegetation for their eggs.
The start of their anecdote. The album's other cards are for you to discover in the game.
Alligatoridae
Alligator mississippiensis · Least concern
Male American alligators court females with infrasound, too low for human ears, and all alligators bellow to claim territory and find mates. Big males measure 3.4 to 4.8 m and weigh up to 450 kg. The mother guards her nest of plants and mud, carries the hatchlings to the water in her mouth and protects them for up to three years, rare care for a reptile.

Alligatoridae
Melanosuchus niger · Least concern
Greenish-black, sometimes almost jet-black: the colour of adults gives the black caiman its name. Reaching 5 m or more, it is the largest predator of the Amazon basin and the largest member of the alligator family; very old males may weigh up to 750 kg.

Alligatoridae
Caiman latirostris · Least concern
A broad-snouted caiman lays 18 to 50 eggs in two layers, and the slight temperature gap between them matters: eggs at 32 °C or more give males, those at 31 °C or less females. Hunting was its greatest threat until South American countries banned it and populations recovered.
