1. Symbiosis & Invasive Species

2. Our goal for today is to answer these questions:
What is symbiosis?
What are the 3 different kinds of symbiosis?
What are some examples of symbiosis?
What are invasive species?
What are some “real world” examples of invasive species?

3. Symbiosis What it means: Two organisms that live together
Temporarily or for a longer time
At least one of the organisms benefits from the relationship

4. What are the different kinds of symbiosis?
Mutualism
Commensalism
Parasitism
both organisms benefit
one organism benefits
one organism benefits
one organism is unaffected
one organism is harmed

5. Organism One Organism Two
Mutualism
Organism One Organism Two

6. Organism One Organism Two
Commensalism
Organism One Organism Two

7. Organism One Organism Two
Parasitism
Organism One Organism Two

8. What symbiotic relationship is this?
Clown Fish & Anemone
This clown fish swims in the anemone and gets protection, since its predators will get stung. The anemone is unaffected.
What symbiotic relationship is this?
commensalism

9. What symbiotic relationship is this?
Loa Loa Worm & Human
This worm infects human the blood stream and gets a nice warm safe home there. The human may go blind or have other complications as a result.
What symbiotic relationship is this?
parasitism

10. What symbiotic relationship is this?
Shark & Remora
The remora attaches itself to the shark and saves energy since it doesn’t have to swim, and it gets to snack on the sharks kills. The shark doesn’t get anything.
commensalism
What symbiotic relationship is this?

11. Moray Eel & Cleaner Fish
This moray eel has a small fish cleaning between its teeth. The eel gets a clean mouth while the cleaner fish gets a nice meal.
mutualism
What symbiotic relationship is this?

12. What symbiotic relationship is this?
Cattle & Egrets
As these cattle walk around eating grass they stir up lots of insects. The egrets hang around and get a yummy meal of insects.
What symbiotic relationship is this?
commensalism

13. Tapeworm and Dog parasitism
The tapeworm attaches to the intestinal wall of the dog and takes nutrients consumed by the dog.

14. Emperor Shrimp & Sea Cucumber
This tiny emperor shrimp is riding along on the back of a sea cucumber (a long worm-like starfish relative) while it crawls along a sandy bottom. The shrimp gets to travel around under the protection of its much larger partner, and the sea cucumber doesn't seem to mind.
commensalism
What symbiotic relationship is this?

15. What symbiotic relationship is this?
Antelope & Ox Bird
This ox bird hangs out on the antelope and gets a delicious meal of bugs living on the antelope. The antelope gets rid of parasites.
What symbiotic relationship is this?
mutualism

16. Goby and Alpheid Shrimp
This alpheid shrimp (on
the right) uses its strong claws like a bulldozer to create a burrow in the sand. The shrimp is nearly blind. It relies upon its partner, the sharp-eyed goby, to warn of danger. When a potential predator approaches, both animals disappear quickly into the burrow
mutualism
What symbiotic relationship is this?

17. Wrasse & Batfish Can you see the two cleaner wrasses are
removing parasites from a batfish? One of the wrasses has entered the gill slit of the batfish, and may even enter its
mouth in search of food. The batfish gets a bath and the wrasse gets a meal.
What symbiotic relationship is this?
mutualism

18. Hummingbird Moth & Flower
mutualism
This hummingbird moth is drinking the nectar of a flower. The flower gets pollinated (the moth brings pollen from other flowers) and the moth gets a tasty meal.
What symbiotic relationship is this?

19. Invasive speices- A species that is not native to the area.
It is introduced usually by humans to solve an ecological problem.
But over time.. It over runs the ecosystem and takes over and becomes a nusance.

20. Ex. Grass carp- eats algae, then gets so big it overrides all other fish

21. Ex. Kudzu- Brought here to control erosion… now a problem!

22. Ex. Red ants…
Came to southeastern United States as stowaways on ships.

23. Ex. Burmese pythons

24. You should now have the following outlined on your paper.
Let’s Review
You should now have the following outlined on your paper.

What are the different kinds of symbiosis?
Describe one example of each kind of symbiotic relationship.
What is an Invasive species?
Give some “real world” examples of invasive species.
