Mutualism(+/+)—What does this mean?

Cleaner Fish and the Moray Eel• The cleaner fish eats

parasites and food bits out of the inside of this moray eel. It gets a meal and is protected from predators by the fierce eel.

Commensalism (+/0)—What does this mean?

Barnacles and WhalesOne species benefits while the other is unaffected

• Barnacles need a place to anchor. They must wait for food to come their way. Some barnacles hitch a ride on unsuspecting whales who deliver them to a food source. This does not affect the whale in any way.

Parasitism (+/-)—What does this mean?

One species benefits while the other is harmed

Bedbugs• Bedbugs are small,

nocturnal parasites that come out of hiding at night to feed on unsuspecting humans.  They feed exclusively on blood!  Their bites often result in an allergic reaction.

Tapeworms• The definitive host of the

cucumber tapeworm is a dog or a cat (occasionally a human). Fleas and lice are the intermediate host. the dog or cat becomes contaminated when the eggs are passed in the feces, and the flea or louse ingests the eggs.  The dog or cat (or human) is infected when they ingest a flea or louse.  Hence the importance of controlling fleas on your pet!

Predator-Prey(+/-)—What does this mean?

• What is pictured is the hawk killing a mouse. The hawk benefits while the mouse doesn’t.

Four Types of Symbiosis

• Mutualism (+/+)

• both species benefit

• Commensalism (+/0)

•   one species benefits, the other is unaffected

• Parasitism (+/-)

•   one species benefits, the other is harmed• Predator-Prey (+/-)• one species benefits, the other is killed
