What do whales eat? Krill or plastic?

Balad'EAU is currently at the HUMPBACK WHALE WORLD CONGRESS, in Santo Domingo, Dominican Republic. Since we have access to the world's greatest experts on this species, I wanted to ask them YOUR questions about humpback whales. Today's question comes from Line, in Québec, Canada who is wondering why humpback whales feed on the tiniest animals like krill, and what is the amount of krill (or which other species) they need to ingest in order to fulfill their food needs? I found the answer from two eminent scientists, Dr. Joy Reidenberg and Dr. Alexander Werth, experts in whale physiology and feeding. Let's listen to their answer. Do you have questions about the life of humpback whales? Email us at info@baladeau.media, or on facebook or instagram, in text or audio, and I'll find you the expert, and the answer to what you want to know!
