How Many Species Are There in the Sea? Marine Taxonomy Explained

Naming ocean life is the first step toward protecting it. In a live conversation with his former professor, host Clark Marchese asks marine biologist Dr. Manuel Caballero Gutiérrez how many species live in the sea and why the answer remains uncertain. The episode follows marine taxonomy through deep-sea expeditions, DNA analysis, museum collections, and formal species descriptions, connecting species discovery with marine biodiversity, extinction risk, and conservation.
