Every year like clockwork, animals both big and small are driven by a
natural instinct to move, in order to survive. On both land and sea,
they fight the odds and the forces of nature to breed, feed, or lead and
carry on for future generations. This reader is an introduction to the
treacherous trek of the zebra, walrus, and Christmas Island red crab to
overcome obstacles that include hungry cheetahs, stinging yellow crazy
ants, and even their fellow species to make the often impossible journey
of their lives.National Geographic supports K-12 educators with ELA
