Marine science students at East Islip High School had the opportunity to dissect dogfish sharks in March. Using their hands, rulers, scissors and scalpels, each group of students measured their shark’s length and width, laternal line, gill slits, and the size of its dorsal, pectoral and pelvic fins, liver, gall bladder and intestinal tract. They also located and examined the placoid scales, spiracles, nostrils, ampullae of lorenzi, teeth, cloaca, reproductive anatomy, esophagus, heart, gill pouch and gill rakers.

“A shark dissection is a fascinating hands-on experience for high school marine science students because it allows them to explore the anatomy and physiology of one of the ocean’s top predators,” Director of Mathematics and Science Dr. John Genova said. “By examining structures like the gills, liver and spiral intestine, students gain a deeper understanding of how sharks are adapted for survival in their environment. It also provides a unique opportunity to study biological concepts such as organ function, buoyancy  and sensory systems up close. This interactive learning experience can inspire a greater appreciation for marine life and the importance of ocean conservation.”
