Now, let's get to the bigger crabs. You've got your blue crabs, which can grow up to 8 inches across, and your Dungeness crabs, which can reach a whopping 10 inches. But those are just the warm-up acts - the main event is the Japanese spider crab, which can stretch its legs out to a mind-boggling 12 feet from claw to claw!
Can you imagine having a pet crab that's bigger than your coffee table? Okay, maybe not as a pet, but you get the idea - these crabs are massive! And it's not just their leg span that's impressive, either - some Japanese spider crabs can weigh up to 40 pounds, which is like trying to wrestle a large dog (but, you know, with more claws).
But here's the thing: even though Japanese spider crabs are the biggest, they're not necessarily the heaviest. That title goes to the Alaskan king crab, which can weigh up to 25 pounds and measure 6 feet across. It's like the difference between a large pizza and a small car - both are impressive, but in different ways.
