Have you ever seen a humpback whale lunge feeding? The yellowish content inside of it's mouth is called baleen. Baleen is a filter-feeding system in which humpbacks push the water out their mouths and filter krill or small fish like anchovies in, that way food remains in the whale's mouth.🐋 Book your trip now using website link in the bio! #whale #wildlife #photography #sea #ocean #travel #california #viral #fun | Oceanic Expeditions
