Tiger
No two tigers have the same stripes, and the pattern is on their skin as well as their fur.
Asia
Tokay Gecko
A tokay gecko’s toes are covered in millions of microscopic hairs that stick to surfaces by molecular forces, inspiring scientists to invent ‘gecko tape’.
Walrus
A walrus finds clams on the dark seafloor with hundreds of sensitive whiskers, then sucks the soft body out of the shell with powerful suction.
White Stork
White storks avoid long sea crossings on migration, funnelling over the Strait of Gibraltar and the Bosphorus in huge flocks that ride warm air currents.
Wild Boar
The wild boar is one of the most widespread mammals on Earth and the wild ancestor of all domestic pigs.
Wild Water Buffalo
The wild water buffalo has the largest horns of any living bovid, spanning up to about 2 metres.
Wild Yak
Wild yaks live higher than almost any other large mammal, grazing at altitudes above 5,000 metres where temperatures drop below −40 °C.
Wolverine
Wolverines can travel huge distances: one young male walked more than 800 km from Wyoming to Colorado.
