r t h e Tundra B I O M E E X P L O R E R S Laura Perdew Illustrated by Lex Cornell T o u The tundra is locked in ice, quiet and barren, Through the long, cold, dark winter. Finally, in the spring, when the sun rises higher and the days are warmer, The sea ice breaks apart and life returns. Algae bloom into a buffet beneath the sea ice where Antarctic krill feast. Gentoo penguins hop and waddle ashore to lay their eggs. Humpback whales splash and dive. Orcas stalk the sea. Antarctic terns migrate from the Arctic. Southern elephant seals bask and bellow on the shore. Then, when the days shorten at the end of summer, the tundras of the Arctic and Antarctica freeze again and grow quiet.
