We received this crab tray as part of a gift. As you can see, there are numbers around the edge. Does anyone have an idea of their purpose? My WAG is it has something to do with sizing crabs, but just a WAG.
ETA: the tray is about 20” in diameter
It looks like latitude indicators you’d get if you sliced a geographic globe in two at the poles. Which doesn’t have a strong link to crabs.
… unless one believes the legend that the continents rest on a layer of giant multi-legged monsters whose pincers are the size of Ireland.

Crabs all the way down
The product description for the tray says “boasting a bright red crab, nautical trim…” ‘’
So yeah, I think it’s just decoration to suggest a nautical compass.
Thanks all, guess I over thought it
Someone on this board overthinking something? Inconceivable!
(grin)
I think it’s to keep track of how many crab claws you’ve eaten so no one at the table gets more than their share.
I just made that up. 
And wanted an excuse to use the crab emoji.
My guess is it has something to do with wagering.
I’m pretty sure Heracles answered it in one, but I love the idea of some kind of crab roulette.
