Does eating crab lower your blood temperature?

I tried searching “crab temperature” and got nada so I’m asking.

The reason I’m asking is that Iron Chef seems to think eating crab meat lowers your blood/body temperature. I would not know, as I don’t eat shellfish.

So is this true? If so, why? If not, why would someone think it is true?

Perhaps it has something to do with crabs being a watery, sea creature, and thus having a cool damp humour:
