* Blue whales are the largest animals on Earth, reaching lengths of up to 100 feet and weighing up to 200 tons.
* Humpback whales are also very large, but they are significantly smaller than blue whales. They typically reach lengths of 40-60 feet and weigh 25-40 tons.
So, when someone says "swole whale," they are likely referring to the blue whale because of its immense size.
