From A Wiki of Ice and Fire
Pouch tigers[N 1] are an exotic species of marsupial animals[N 2] from an unknown land, far from Westeros or the Free Cities.
According to Syrio Forel, the Sealord of Braavos keeps live specimens in his menagerie.
Hear me. The ships of Braavos sail as far as the winds blow, to lands strange and wonderful, and when they return, their captains fetch queer animals to the Sealord's menagerie. Such animals as you have never seen, striped horses, great spotted things with necks as long as stilts, hairy mouse-pigs as big as cows, stinging manticores, tigers that carry their cubs in a pouch, terrible walking lizards with scythes for claws. Syrio Forel has seen these things.
- ↑ No formal name has yet been given for these creatures.
- ↑ The description given of these animals appears similar to a thylacine, also known as the "Tasmanian tiger" or "Tasmanian wolf" due to their superficial resemblance to these respective animals. In real life, marsupials are found primarily in Australia, although George R. R. Martin has stated that he is not sure if a counterpart of Australia exists in the world of A Song of Ice and Fire.
