Luke Tipple invites “The Lost Shark Guy,” Dr. Dave Ebert, who is personally responsible for finding dozens of shark species that were either previously unknown to science or thought to be extinct.

Host Luke Tipple is joined this week by renowned Harvard professor, Dr. Avi Loeb, who recently led a deep-sea expedition to discover if evidence for advanced alien life crash-landed off the coast of Papua New Guinea in 2014. They discuss the recent Congressional UFO hearings, how the last seventy years of research into extraterrestrial life has been potentially misguided, and the challenges of searching for tiny objects on the bottom of the ocean.

In this season’s final episode, Luke welcomes Emmy-winning filmmaker and conservationist Shawn Heinrichs to discuss the state of sharks in the ocean.
