Orcinology (KILLER WHALES) with Jorge Vélez-Juarbe
Summary
Alie Ward and Dr. Jorge Vélez-Juárve explore orca biology, correcting the misconception that they are "killer whales" by noting they are actually the largest dolphin species. The episode covers their global distribution, distinct resident and transient populations, and the tragic history of captive orcas like Keiko. They also discuss evolutionary origins, unique anatomical features like phonic lips, and recent behavioral mysteries such as "salmon hats."
