It's Shark Week! Tune in to hear 'Hooked on Sharks,' the latest episode of 'On the Line,' a new podcast from our colleagues at NOAA Fisheries. 'On the Line' features interviews with NOAA scientists who study fish, marine mammals, and other ocean life. In 'Hooked on Sharks,' we hear about a research project to see if a special type of hook can help vulnerable populations of sharks to survive.
