Arapaima: Mother of All Fish

Get to know the largest freshwater scaled fish with a face that looks like a topographical map of Mars: the Arapaima. Wait, there's more: they excrete a milk-like substance from their head! An ichthyologist who works at the Field Museum in conservation science, Dr. Lesley de Souza, takes us to the Amazon and Essequibo basins in South America where she's learned from Indigenous communities while exploring the habits of this astronomical, air-breathing fish (known by some as "mother of all fish").
