A professor at James Cook University was bringing his class to the Paluma Rainforest and was nice enough to allow me to tag along. We started our journey at the very top of the rain forest and eventually worked our way down to the bottom analyzing plants, animals, and water systems at each level. At the very top of the rainforest was a man built dam. This dam supplied Townsville Australia with a lot of their water.
Next, we headed down Paluma to the next level of streams. I found out that a lot of nutrients from the water can be found at the top of a waterfall. All of the water flows to this area so living organisms tend to hang around the area and grab the nutrients from the water. There is a blackish material all over the rocks near at the top of the waterfall. I rubbed my finger on it and guess what I saw!!!!! Check out the video below!!
Black Fly larvae!!! The larvae use tiny hooks at the end of their abdomens to attach to the rocks. Once the larvae catch enough nutrients they change into the pupa stage and remain under water until they emerge as an adult in a bubble that floats to the top! Cool!!!
We headed down to another stream and lifted rocks to find a variety of organisms that lived underneath them. Below are pictures of a crayfish and a spider. Both live in the stream and feed on other microorganisms. Don't worry we released the crayfish from the tube once everyone had a look:)
Overall it was an excellent day! Now for the question! Remember to leave your name in the response. This is an easy one. What stage of metamorphosis was not mentioned in the paragraph about the black flies? 1st one to get the answer right gets a prize when I get back!! Also, I'll have another post up by Wednesday so check back!!!!!
