These hyenas and animals that come to drink at watering holes have very different adaptations to living on land than the animals that live in the watering hole itself.

Terrestrial organisms have a very different set of adaptations (qualities that enable them to survive) than do aquatic organisms. Both terrestrial and aquatic organisms have different adaptations that help them move, reproduce, maintain the right amount of water in their bodies, and complete gas exchange.

While reading this list of adaptations, it's entirely possible you're thinking, "Wait, but what about . . .?" Perhaps you are thinking about dolphins and whales that live in a marine biome, yet they have lungs for respiration and only have one or two offspring at a time. Remember, these are just some common adaptations. As you study specific biomes, you will learn more about adaptations specific to each of them. Next, you'll learn how biomes are changing, but before you do, see if you can match the adaptations below to the correct type of biome.
