Humpback Whales
Tubercles for Hydrofoil and Propeller Design
The humpback whale is one of the largest animals on Earth, often 12 to 16 metres long and weighing tens of tonnes. Yet it is surprisingly agile. Humpbacks feed by swimming in tight circles beneath schools of fish, blowing curtains of bubbles to trap them, then lunging up through the trapped prey. To turn tightly, they rely on their enormous flippers — the longest of any whale, up to about a third of their body length.
