At #CCU, marine science students are getting hands-on experience collecting tissue samples from live sharks to support research.   After identifying and tagging the shark, students collect a small blood sample, fin clip, or tissue plug near the dorsal fin. These samples help researchers study how sharks regulate salt levels and reveal where and how they feed in the ecosystem through stable isotope analysis.   🎥 Part 4 of a 4-part series on the CCU Shark Project
