Extreme Nature!

A blue whale is extreme­ly big—as long as two school bus­es placed end to end. The stout infant fish is extreme­ly small — as small as the eras­er on a pen­cil. A pere­grine fal­con is extreme­ly fast — it can dive at 200 miles per hour. A sloth is extreme­ly slow — it might take three hours to move one mile. But the biggest, the small­est, the fastest, the slow­est, and every oth­er liv­ing crea­ture on Earth need to find food, stay safe, and raise young. Extreme Nature! lets you in on some of the amaz­ing ways plants and ani­mals accom­plish these goals.
