Bats versus Amphibians
Use the photos and facts to compare amphibians and bats. Then answer the questions below.

  1. Despite the expression “blind as a bat,” all bats can see -- some very well.
  2. Many bats catch their meals using a method called echolocation. They send out high-pitched squeaks. When these sounds bounce back off surrounding objects as echoes, bats instantly analyze the pitch and intensity. Bats use echolocation to figure out what’s around them, including the shape of objects and the distance they are from objects.
  3. Fishing bats, like all meat-eating or carnivorous bats, have amazing hunting abilities. If a minnow’s fin is sticking out of the water by just two millimeters, a bat can use echolocation to detect it.
  1. There are more than 4,900 different kinds of amphibians in the world today, including frogs, toads, salamanders, and newts.
  2. Amphibians spend the first part of their lives as larvae in water, breathing with gills, or inside large eggs. Then their bodies transform or metamorphose and they may live in the water or on land, breathing with lungs.
  3. Amphibians are cold-blooded creatures and generally have moist skin.
  4. Frogs don’t drink. They get the water they need to survive by absorbing it through their skin.

Answer the questions based on the evidence.
