Because one adventure isn’t enough for the day, they began the morning in the lab performing a shark dissection on an Atlantic sharpnose shark. With the help of educators Andrew and Jesse, campers got to learn about the anatomy of a shark up close.
The Pocomoke River is surrounded by different types of trees that affect the water and make it appear darker, the most common of which is the loblolly pine along with red maple and bald cypress trees. Campers were challenged to think about different adaptations that fish have to live in freshwater, marine, or brackish ecosystems. At the Y, there were bluegills and sunfish, and at the second stop along the upper Pocomoke River there were many channel catfish.
Campers compared the salinity of these waters and learned about osmoregulation, the process an organism undergoes to maintain homeostasis, or to keep its body fluids at the right level of salinity. They caught several different kinds of fish, including a pumpkinseed and many different sizes of channel catfish. When an averagely sunny day turned into pouring rain, these dedicated young scientists stayed out in the rain in a classic “you know you love marine science when” moment.
