Presentation transcript:

Symbiosis Any close and long-term biological interaction between two different biological organisms. Usually the organisms are of different SPECIES.

Ox and Egret Birds eat bugs from back of ox. Bugs bite Ox and can cause infections.

Plover cleans teeth, prevents infection.

Barnacles get transport, food. Whales usually unharmed.

Clown fish have a mucus coating that protects from sting.

Cymothoa exigua Fish lice move in through gills eventually replace tongue!

100 trillion bacteria in our guts!

Mushroom provide nutrients, plant provides sugars

Another example with humans: The African honeyguide bird leads humans to bee hives. It uses a particular call to guide people to the location of a hive. Once near the hive it changes its call to alert the humans.
