Katrina Lohan, head of the Coastal Disease Ecology Laboratory at the Smithsonian Environmental Research Center

Alejandra Morales Picard, psychologist at Montgomery College

Rebecca Sturniolo, assistant curator of the America Trail at the Smithsonian National Zoo

Patty Storms & Morty Bachar, otter neighbors
