Predation Experiment

Augusta Creek

Journeying on to Augusta Creek where you will find all sorts of tasty aquatic organisms, northern green  frogs, dragonflies,  B.E.A. Utiful damselflies (Shout outs to our wonderful Professor, Idelle)  crayfish, and plenty more.

 Crayfish are crustaceans related to lobsters and usually eat anything they can catch with their claws but are usually scavengers of dead plants and animals.

Isn't he adorable! Try touching his claws! 

In class, small groups created different predation experiments but only one will be discussed. In our experiment we collected six predators, crayfish, stone flies, dragonflies and one unknown larva and placed them in beakers in a freshwater habitat with possible prey wondering if they coexist or would the predators enjoy a good meal. 

Turns out 4/6 predators were alive, 2/6 predators were dead,  3/6 prey were dead, and 3/6 of the prey were gone.

Some of the predators may be selective of their prey and some may have eaten the prey for survival reasons.  

The adventure of catching these predators were quite easy except for putting the crayfish in the beakers. They're very jumpy! Overall, there were more experiments on predation and hopefully you will read more!
