This reminds me of a news story from many years ago about a research study that won the Ig Nobel Prize. The research study was about how almost all mammals weighing over 3 kg take just about the same amount of time to empty their bladders when urinating.

I need to know if this is also true of aquatic animals. A blue whale is ~50x the size of an African elephant. Does that mean that a blue whale expels some 2100 gallons (~8000 liters) in 20 seconds?
