Own every animal of the family Ranidae.
True frogs have smooth, moist skin. Their long hind legs are built for leaping and swimming. Their tadpoles live in water before metamorphosis. The family is found on most continents. Males call to attract females. Many lay their eggs in clumps in the water.
The start of their anecdote. The album's other cards are for you to discover in the game.
Ranidae
Rana dalmatina · Least concern
Its unusually long hind legs let it jump up to two metres, which earned it its name. Its call can last 12 seconds and sounds almost like a clucking chicken, but males often call underwater, so it carries only a short way. Spawning lasts just a few days, and each clump holds 450 to 1,800 eggs fixed to branches or stems under water. In Britain it is rated Critically Endangered.

Ranidae
Rana temporaria · Least concern
Europe's most familiar frog lives as far north as Scandinavia inside the Arctic Circle. In winter it sinks into the mud and dead leaves at the bottom of ponds and streams, where the oxygen it takes in through its skin is enough for a cold, motionless body.

Ranidae
Rana graeca · Least concern
Greek stream frogs sing in hiding. Right after hibernation, from February to April, the males call from under or above the water in dark places such as crevices under roots or stones. Females stick masses of 200 to 2,000 eggs to the roof of a cavity, and the males seem to guard them for a while.
