A few sample questions

1. 1. Which animal is the fastest land animal on Earth, reaching speeds of up to 70 miles per hour?

   Answer: Cheetah

   The cheetah is the fastest land animal, reaching up to 70–75 mph in short bursts. It can accelerate from 0 to 60 mph in just about 3 seconds — faster than most sports cars! (The peregrine falcon is faster overall, but only in a steep dive, not on land.)

2. 2. Which large animal sleeps standing up?

   Answer: Horse

   Horses can doze lightly while standing up, thanks to a special 'stay apparatus' in their legs that locks joints in place. They do lie down for deeper REM sleep, but it is only for short periods.

3. 3. Which ocean animal keeps growing throughout its entire life?

   Answer: Lobster

   Lobsters keep growing for as long as they live, molting their shells and getting bigger over time (though the rate slows with age). Some have been found that are over 100 years old!

4. 4. What is the largest animal that has ever lived on Earth?

   Answer: Blue whale

   The blue whale is the largest animal ever known to exist on Earth. It can reach up to 100 feet long and weigh as much as 200 tons — even heavier than the largest dinosaurs.

5. 5. A group of flamingos is called a 'flamboyance.' What is a group of crows called?

   Answer: A murder

   A group of crows is called a 'murder,' one of the most memorable collective animal names. No one is entirely sure how that name came about, but it has been used in English since at least the 15th century.

Things you'll learn along the way

• ✓The hummingbird is the only bird capable of sustained backward flight. Their wings beat in a figure-eight pattern up to 80 times per second, giving them extraordinary aerial control.
• ✓Of an octopus's three hearts, two branchial hearts pump blood through the gills to pick up oxygen, while one systemic heart pumps oxygenated blood to the rest of the body. The systemic heart actually stops beating when the octopus swims, which is why they prefer crawling.
• ✓Bats are the only mammals capable of true powered flight. Flying squirrels and gliders only glide — they cannot generate lift or gain altitude the way bats can.
