The Earth is a somewhat pear shaped ellipsoid, with a slightly larger southern hemisphere than northern hemisphere. No single mathematical formula works for all of the Earth's surface, so different regions are represented by different formulas. Position coordinates determined for one formula (datum) will usually not match the position values determined by another datum.

On the surface, Antarctica may seem very similar to the Arctic, but the two areas are, in fact, very different. The Arctic is an oceanic basin lying beneath a thin layer of ice. Antarctica is a land continent buried under a permanent ice sheet and surrounded by ocean. The ice sheet that covers almost all of Antarctica is more than a mile thick. Beneath the weight of the ice sheet, the rocky surface of Antarctica often sinks thousands of feet below sea level.

"I wonder if the spinning of the earth may something to do with the bulge of the equator?"

Yes it does.

(It also means that the attraction of Earth's gravity is somewhat counter-acted in the equatorial regions.)

That is why a spaceship launched from the equator would require less fuel to reach orbit then one launched from more northerly or southerly regions.
