1. Adaptations of Aquatic Life
Post Scavenger Hunt

2. Aquatic Systems https://www.youtube.com/watch?v=kL-9TB4qAho
What are the 2 types of Aquatic Ecosystems?
What are some examples of Freshwater Systems?
What are some examples of Saltwater Systems?

3. Think about It!
What do all animals need to survive?

4. Animal Needs
Food – Food may be floating, at the surface or at the bottom, depends what area they live in.
Water (retention and supply) – Saltwater organisms need to retain freshwater to survive while freshwater organisms need to regularly remove water from their systems.
Gas exchange (oxygen) – Dissolved oxygen in water
Suitable shelter - what is available (eg. plants, rocks)
Temperature regulation – Ectothermic vs Endothermic, different environments

5. Scavenger Hunt
Make your way around the room and in the hallway area just outside of class to fill out the rest of your notes.

6. Adaptation: Gills Purpose: Used for oxygen exchange (pulls dissolved
oxygen out of the water)
Found in: Fish, Sharks, some insects, crustaceans (shrimp, lobsters and crabs), Mud Puppies, Mollusks (Snails, Clams, Oysters), Sea Stars, Sea Urchins

7. Adaptation: Streamline Body Position
Purpose: To move easier in the water, require less food
Found in: Fish, Whales, Dolphins, Otters, Insects, Worms, leeches

8. Adaptation: Ectothermic (body temperature the same as their surroundings)
Purpose: To maintain body temperature in aquatic environment
Found in: Animals that are not mammals (e.g. Fish, Reptiles, Insects, Crustaceans (shrimp, lobsters, crabs), Amphibians, Mollusks (Snails, Clams, Oysters)), Worms,

9. Adaptation: Blubber Purpose: To maintain body temperature
Found in: Aquatic Mammals (e.g. Seals, Whales, Manatees)

10. Adaptation: Fins Purpose: To move in water and control motion
Found in: Fish, Sharks, Aquatic Mammals (e.g. Seals, Whales, Manatees)

11. Adaptation: Scales/Smooth Skin/Smooth Fur
Purpose: To move easier in the water (reduces drag)
Found in: All Aquatic animals

12. Adaptation: Diapause (animals remain inactive for a period of time)
Purpose: To survive in undesirable conditions
Found in: Insects, some fish

13. Adaptation: Calcium Carbonate Skeleton/Exoskeleton/Shell
Purpose: To have strong supportive structures, Protection from predators
Found in: Mollusks (Snails, Clams, Oysters), Coral, Sponges,

14. Adaptation: Tube Feet Purpose: to remain on the bottom/Catch food
Found in: Sea Stars, Sand Dollars, Sea Cucumbers

15. Adaptation: Suction Cup Feet
Purpose: To catch prey/move near surfaces
Found in: Octopus, Squid

16. Adaptation: Sealable blowhole/nostrils
Purpose: To breathe from lungs and to not have water enter
Found in: Mammals (beavers, whales, dolphins, Sea lions, Otters), Diving Birds, Amphibians, reptiles

17. Adaptation: Webbed Feet
Purpose: To swim more efficiently
Found in: Birds, Beavers, Amphibians, Otters

18. Adaption: Permeable Skin
Purpose: To allow for water/oxygen to enter the body and to allow for salts to leave the body
Found in: Amphibians, worms

19. Adaptation: Baleen Plate
Purpose: To feed on small prey (krill)
Found in: Baleen Whales (Humpback Whales)

20. Adaptation: Migration Patterns
Purpose: To move between locations where different needs are met in different areas (example food in winter near equator and food in summer near the north)
Found in: Fish, Whales, Reptiles, Birds

21. Important Adaptation: Swim Bladder
Purpose: To stay afloat
Found in: Fish, Sharks

22. Task: Create an Aquatic Animal
Your task is to make an animals with a minimum of 5 adaptations to an aquatic environment. With this, you can describe or draw and label the parts that are adaptations to your animal
