Are there any oceans without crabs?

Hello viz_think,

All oceans have crabs.  (This was apparently a more recent discovery
in the Southern Ocean than in the others.)  See, for example:

"Blue Crab" [located in the Atlantic Ocean]

"The Vent Crab" [located in the Pacific Ocean]

"Ocypodinae" [some of which are located in the Indian Ocean]

"Snow Crab," by François Plante [located in the Arctic Ocean]

et al. (Ecology, 86(3), 2005, pp. 619?625) [concerning crabs in the
Southern Ocean]

These are the five oceans.

great answer with nice examples. And fast too.

None in the Sea of Tranquility as far as I know.

The Sea of Tranquility is a sea, not an ocean, so it doesn't count.  :-)

The Sea of Tranquility is on the Moon...

Yes, that too.
