Last week, volunteers monitoring a sea turtle nesting beach on Virginia Key came across a beached lemon shark. They called in scientists from the University of Miami’s RJ Dunlap Marine Conservation program, including myself . Dunlap program director Dr. Neil Hammerschlag decided to film the necropsy to use as an online teaching tool. The end result, edited together by Dunlap program multimedia specialist Christine Shepard, is below. Check it out to learn about the internal anatomy of a shark, as well as the process that scientists use to determine causes of death in marine organisms. If you have any questions about the process or about the animal, please leave them as comments below.
