There are two words that everyone should know before they go whale watching in Juneau:
“Bubble,” and “feeding.”
That’s the name of the explosive maneuver that humpbacks use when they’re feeding. Believe it or not, when gorging themselves on schools of krill in Alaska’s nutrient-rich waters, these 40-ton giants can gulp the volume of an entire African elephant. Even with all of that water, however, their throat is only the size of a grapefruit, and the majority of water seeps through their baleen like a massive, keratin-plated sieve.
