In this episode of Shark Week: The Podcast, marine biologist and shark expert, Luke Tipple recalls his first shark interaction as a child spear fishing with his father and how that was the moment that sparked a life-long passion to study and protect sharks. He breaks down the critical role of sharks in keeping healthy ecosystems in all earth’s oceans and why our way of life would suffer greatly if sharks were no longer with us.  He details the unique places sharks call home and describes shark species' diverse needs in habitats -- from warm, tropical ocean waters to deep, icy ocean waters. Connect with the podcast: https://podcasts.apple.com/us/podcast/shark-week-the-podcast/id1527053422Follow Discovery+ on Instagram: https://www.instagram.com/discoveryplus/Follow Luke Tipple on Instagram: https://www.instagram.com/luketipple/Learn More About Shark Week: https://www.discovery.com/shark-weekFind episode transcripts here: https://shark-weeks-daily-bite.simplecast.com/episodes/how-sharks-keep-our-ecosystems-healthyFor more about sharks, head to SharkWeek.com
