Marine Phyla Lab



In our lab we were trying to find what was the most marine phyla found in the tidepools. The nine phyla we were looking for were Porifera, Cnidaria, Platyhelminthes, Annelida, Mollusca, Arthapoda, Echinodermata, & Chordata. To gather data we used a quadrat and a transect tape and we counted how many creatures of each phyla were in a quadrat, we repeated this about 5 times. I hypothesized that the Porifera and Mollusca would be most present during our lab. I was half correct, because the Mollusca phyla was represented the most. During our research we could have made many mistakes, the biggest would have been miscounting the data. I enjoyed doing this lab and going outside to the tidepools, it was really interesting to see all the little sea creatures. I learned many new things, before this lab I didn't even know what a phyla was, and now I know all the nine marine Phyla.
