Morning navigation led National Geographic Orion around the Alftavikurfjall region, the northeast corner of the island of Iceland. This area is particularly opportunistic for the likes of whales, particularly minke or humpback. Today, the guests aboard the ship were extremely lucky to view both! These are both baleen whales, animals that take in huge amounts of water by expanding their ventral pleats, followed by sieving the water out through their massive mouths. Baleen is a construct made of keratin, the same protein that builds our fingernails and hair. The baleen hangs down from their upper jaw and acts as an extremely effective filter for these animals, instead of relying on tools like teeth (which would prove useless against their miniscule prey choice). The ship saw these whales lunge feeding, bubble net feeding, and lolling about at the surface. This activity was perfectly timed, as marine mammal expert Madalena was about to give her lecture on the very same creatures in the lounge.
