Each time David Shiffman looks at a shark, he still gets that excited feeling he experienced when he visited the Pittsburgh zoo as a child.
Mr. Shiffman, now a marine conservation biologist at Arizona State University, is a South Hills native who remembers going to the zoo regularly growing up in the 1990s and early 2000s, and he worked there during his freshman year of college.
He returned to the Pittsburgh Zoo & PPG Aquarium on Saturday to promote his new book about the mighty fish and the misconceptions that surrounds it.
