Episode Description from the Publisher

 How many species are there in the ocean? Marine biologist and taxonomist Manuel Caballero Gutierrez joins Oceanography to explore one of the biggest unanswered questions in marine science: how much life have we actually discovered? From deep-sea expeditions and biodiversity surveys to DNA analysis and museum collections, this episode unpacks how scientists identify, classify, and name new marine species, and why humanity may still know only a fraction of the organisms living on Earth. The conversation explores ocean biodiversity, taxonomy, extinction, climate change, and the growing urgency of documenting life in the sea before ecosystems are permanently altered. A fascinating look at ocean exploration, scientific discovery, and the hidden complexity of life beneath the surface.Support our science communication directly by donating to Pine Forest Media or directly on PayPalEpisode Guests: Dr. Manuel Callebar GutierrezBrowse Dr. Callabar Gutierrez's publications on Research GateListen to Pine Forest Media’s NEWEST PODCAST GREEN FREQUENCYEpisode Transcript  and more information on the Pine Forest Media websiteFollow Pine Forest Media on Instagram @pineforestmediaHosted, produced, and edited by Clark Marchese Cover art by Jomiro EmingTheme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Plastic Podcast on Spotify or Apple PodcastsListen to South Pole on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts Hosted on Acast.
