 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.
