 Think to yourself or talk to your partner about all the times you’ve been to the beach, ocean or aquarium!  Did you ever think about what may be living in the water?

 Nemo loves going to school and learning all new things and making new friends every day! See Nemo and his friends at school!

Salt Water

 Swimming with the saltwater creatures! Salt Water Creatures

 What are they?  An arthropod is an animal with a segmented body and six or more jointed legs

 A sea crab is an example of an arthropod.  Examine what makes it an arthropod: Its jointed legs!

 Shrimp are arthropods too!  Look very closely and you see that its body is segmented

 Now that you have swam with the arthropods, now it is time to swim with the sea mammals: Sea Mammals

 What are they?  A sea mammal is a mammal that lives in salty waters.

 The Orca Whale  Orca whales are also known as “Killer Whales”.  They live in cold water.

 There are two types of common dolphins. First, click on the Long Beak Dolphin. Long Beak Dolphin Short Beak Dolphin

 Long beaked dolphins have a longer face than short beaked dolphins Watch them swim!

 The short beaked common dolphin has more of a rounded melon that meets at the beak at a sharp angle. What is a melon?

 A melon on a dolphin is its forehead. It contains oils.  Scientists think that the melon can make sounds that help the dolphins communicate.  Echolocation is how dolphins talk to each other.

 Humpback whales have a hard time keeping quiet!  They make many moans, howls, and cries. Listen to what they have to say!

 Seals can be fierce predators in the water!  They live in the very cold waters in Antarctica, where they eat squid. What is a predator?predator

 A predator is an organism who eats another organism.  In our example, a seal is the predator and the squid is the prey.  A prey is an organism that is eaten by another organism.

 You’ve completed the sea mammal section!  You have had so much fun swimming with the arthropods and the sea mammals, but now it is time to swim with the crustaceans: Crustaceans

 What are they?  They are a class of arthropods.  The difference is all crustaceans have a hard shell with branching limbs.

 Horseshoe crabs are related to spiders and scorpions, not sea crabs!  Horseshoe crabs are found in Maine and Florida.

 Lobsters live in saltwater and breathe through gills.  On the front of their head they have antennae and two eyes on the end of stalks.  Their tail looks like a fan!

You have done such a great job swimming with the salt water creatures. Now it is time to explore the freshwater animals! Freshwater Animals

 There are many animals that live in our oceans, but there are also many who live in freshwater such as a lake, river, or pond!

 Crayfish live in freshwater. They closely resemble a lobster, but they are not related!  Remember, lobsters live in salt water!

 Alligators are commonly found in freshwater, while crocodiles are more commonly found in salt water areas!  Alligators have very muscular and powerful jaws. Check out those chompers!

 Frogs are not always green!  They are usually the color of their environment around them so they can blend in and hide!

 Hippopotamuses spend up to 16 hours of their day in the water!  Their eyes and nostrils are high in their head so they can see and breathe while in the water.

 You are becoming an expert!  You are a great swimmer with the fresh and salt water creatures. Now it is time to explore the aquatic plants!

Not that kind of plant! All plants need water to survive, but some plants live on land and others live in water! Let’s check out the plants that live in the water!

 Coral Coral are soft plants that are related to jelly fish. They live on rocks that they attach themselves to.

 Pronounced: A-nem-oh- ne-s Anemones have tentacles and they respond to even a light touch. Find out who lives in an anemone!

 Lilies ( Lily pads)  Many frogs like to catch some sun on lily pads! They are like little islands to the frogs!

 Seaweed  Seaweed can survive in freshwater and salt water.  They live on the seashore and shallow waters throughout the world!

 Here is a review to get you ready for the quiz.  Click on the picture you feel is the most appropriate answer.

 Which of the following creatures is a horseshoe crab?

 You really know your aquatic biology!  Move on to the next question!

 Go back and carefully look at the pictures. Remember what makes a sea crab different from a horseshoe crab.

 Click on the best choice.

 Think about where the Orca whale lives. Would you find him in a pond or in the ocean? Try the question again!

 The Hippopotamus lives in fresh water and the Orca Whale lives in the ocean, which is salt water.  You are ready for your quiz!

 Now it’s time to put your aquatic biology skills to the test!  Read each question carefully and click on the best response!  Good luck!
