Here's why:
* Size: Blue whales are the largest animals on Earth, reaching up to 100 feet long and weighing up to 200 tons.
* Weight: Even the largest cranes are designed to lift significantly less weight than a blue whale. The heaviest objects ever lifted by cranes are usually much smaller, like large pieces of equipment or structures.
* Fragility: Blue whales are incredibly delicate creatures. The immense pressure of lifting them with a crane would likely crush their bones and internal organs.
In short, the sheer size and weight of a blue whale far exceed the capabilities of any crane.
