Leo Hayes High School

Yesterday afternoon a group of grade 11 students taking an Outdoor Pursuits class at Leo Hayes High School arrived on campus for a two night stay.  For the afternoon the students helped us to gather data on the invasive green crab species along a local shoreline.  We collected and marked 39 specimens, one of which was an egg bearing female.  The smallest crab found was 0.5 cm (wow, someone had good eyes!) and the largest collected was 6.5 cm.  While everyone did really well, the title of crab whisperer would have to go to Zane who found the greatest number of green crabs!  Below are some pictures from the afternoon.    

The crew excited to be in St. Andrews!
