National Science Foundation (NSF)’s Post

Need another reason to be fascinated by sharks? Sharks are all teeth. No, really. Their skin is made up of teeth! 🦷 Their bodies are covered in flat V-shaped scales called denticles, or "skin teeth," that are coated in enamel and have a dentin layer, pulp cavity and blood vessels. Three students went to study sharks for eight weeks this summer through the Research Experience for Undergraduates program Accessible Sharks, at Harvard University. Scientists from Yale University, the University of Florida and Smith College participated. Dakota Law from Smith College is particularly interested in denticles because they help reduce drag when sharks are swimming, allowing them to effortlessly glide through the water. Over the summer, Law learned how to use different kinds of technology to analyze skin samples and collect data on movement. The NSF Accessible Sharks program is an internship program that supports undergraduate students with disabilities to participate in interdisciplinary summer research on sharks.
