Siamese Fighting Fishベタ
Betta splendensVU— Vulnerable
The Siamese fighting fish (Betta splendens), native to shallow, vegetated waters of the Mekong basin in Thailand, Cambodia, Laos, Myanmar, and Vietnam, is a small labyrinth fish that can breathe air at the surface thanks to a specialized organ. Domesticated for at least 1,000 years and historically bred for staged fights between males, it has since been selectively bred into countless ornamental color and fin varieties popular in the aquarium trade worldwide. Wild populations are threatened by habitat loss and pollution and are listed as Vulnerable by the IUCN, even as Thailand designated the species its national aquatic animal in 2019.
