Y Animals

Yak
Bos grunniens
MammalThe yak is a large, long-haired bovine adapted to the extreme cold and thin air of the high Himalayan plateau, able to live at altitudes above 4,000 meters (13,000 feet) that few other large mammals can tolerate. Most yaks today are domesticated and have been kept for thousands of years across Tibet, Nepal, and the surrounding mountains as a source of milk, meat, wool, and transport, while small wild populations still survive on the remote Tibetan Plateau.

Yellow-bellied Marmot
Marmota flaviventris
MammalThe yellow-bellied marmot is a large ground squirrel found in the mountains of western North America, spending nearly eight months of the year in deep hibernation.

Yellowfin Tuna
Thunnus albacares
FishThe yellowfin tuna is a large, fast-swimming fish found in tropical and subtropical waters across the world's oceans, prized both as one of the ocean's most powerful predators and as one of the most commercially important fish species for human consumption. Its name comes from the bright yellow coloring of its dorsal and anal fins, which become especially long and dramatic in mature adults.
