Man, oh man, I sure am sleepy. X.x;;

Anyway, I was thinking about the various Sea Kings in Grand Line (and the Calm Belts), not to mention the inflated mammals like the Dolphins and those Sea Monkeys. Crocus said Laboon was of the biggest species of Giant Whale; since whales are the largest animals on Earth, I made the inference that Laboon was simpy the largest sea beastie introduced in the series.
But now I'm not so sure. The Calm Belt Sea Kings look larger, that Dolphin does too, the ginormously dead beasts that made up the mountains of Little Garden and the big Koi all look equal if not larger. Since the proportions of the sea beasties are maximised for size, it looks weird seeing a giant whale that ends up being shorter than a giant dolphin!
So, how do you lot of Arlong Park think Laboon measures up? I'm surprised I can say all this because I am very sleepy and I'm not sure about the validity of my argument.
