Answer Key
The blue whale is the largest animal ever known to have existed on Earth, reaching lengths of up to 100 feet and weighing as much as 200 tons.
A group of lions is called a pride. A typical pride consists of about 15 lions, including several related females, their cubs, and a small number of males.
Parrots can mimic human speech because of their thick tongues and specialized vocal anatomy. African Grey parrots are considered the most talented talkers.
Photosynthesis allows plants to convert sunlight, water, and carbon dioxide into glucose and oxygen. This process is essential for life on Earth.
All spiders have eight legs. This distinguishes them from insects, which have six legs. Spiders belong to a group called arachnids.
Both koalas and kangaroos are marsupials and carry their young in pouches. Other marsupials include wombats, opossums, and wallabies.
Coast redwoods (Sequoia sempervirens) are the tallest trees on Earth. The tallest known redwood, named Hyperion, stands over 380 feet tall in Northern California.
The Pacific Ocean is the largest and deepest ocean, covering more than 60 million square miles. It is larger than all the land area on Earth combined.
Monarch butterflies make an incredible annual migration of up to 3,000 miles from the United States and Canada to central Mexico each fall.
Bowhead whales can live over 200 years, making them the longest-lived mammals. Note that the Galapagos tortoise is a reptile, not a mammal, and can also live over 100 years.
Penguins are found naturally in the Southern Hemisphere, including Antarctica, South America, South Africa, New Zealand, and the Galapagos Islands -- but never in the Arctic.
The Virginia opossum is the only marsupial found in North America. Female opossums carry and nurse their young in a pouch, just like kangaroos.
Polar bears are the largest species of bear, with adult males weighing up to 1,500 pounds. They are also the largest land carnivores on Earth.
Trees absorb carbon dioxide during photosynthesis and release oxygen. A single mature tree can absorb about 48 pounds of carbon dioxide per year.
An octopus has three hearts: two pump blood to the gills, and one pumps blood to the rest of the body. Their blood is also blue because it contains copper.
