When Jasmin Graham describes her research on smalltooth sawfish, a critically endangered ray with a unique "saw" at the front of its face, she explains how "nothing else looks like this in the ocean; those species evolved to do something no other shark or ray can do." It resonates, and people understand why diversity matters in sharks, she said. She expanded on this same concept to emphasize how diversity also matters in finding solutions to the challenges that threaten elasmobranchs and in those scientists doing that work.
