The National Geographic photos, article, and video of a newly observed phenomenon of frogs hitching a ride on the backs of water buffalo can be used to begin the discussion on relationships of different species. Since little is understood at this time of the specific symbiosis involved, it provides an excellent point of discussion about organisms interactions in the environment.
This phenomenon could stimulate the following driving questions:
Is this relationship beneficial for either species?
Is this relationship harmful to either species?
What could be some benefits/detriments?
Why do the water buffalo tolerate the frogs?
Predict what would happen to either species if the other one was decreased in numbers. What evidence is needed to answer this question?
