Intro. to Marine Biology cont.

On Tuesday the students in the Introduction to Marine Biology course began the morning at Holey Point exploring the intertidal zone and collecting specimens to study further in the lab later that morning. After lunch students performed a lab to investigate whether or not the size of an echinoderm affects how quickly it can right itself when turned over. The afternoon ended with a tour of the Fundy Discovery Centre.  In the evening it was time to learn more about the invasive species of the area.

On Wednesday the theme of invasive species was continued as students marked Green Crabs at
Pottery Creek.  After lunch fish were studied in more detail and the students toured the Atlantic Reference Centre to view their vast and varied collections.

Tracey explains what to look for and where to find it.

Some students stayed on the beach, others tested the waters.

You had to step carefully on the seaweed to avoid slipping.

 

Sea Urchins were found just past the low tide mark.

Here Tracey shows the difference between a Common Periwinkle and a Dogwinkle.

There are some interesting rock formations on the beach.

 

In the lab to try and identify the intertidal and subtidal species collected.

The lab binder was useful in identifying this Green Crab.

It took a lot of patience to wait for some of these echinoderms to turn over.

The touchpool was a very popular part of the tour.
