    Parts may be shallow, but the majority of the Carribbean sea is deep with six very deep basins and trenches.

    see map below. Measurements in meters, not feet.

    ps, On the other hand the Gulf of Mexico is quite shallow in comparison. Did you perhaps mean to ask about the Gulf of Mexico and not the Carribbean ? 

    Here is a map of the Gulf of Mexico with depths.

    The Gulf of Mexico is NOT the impact crater of Chicxulub asteroid that impacted at the End og the Cretaceous period of the Mesozoic era. . the Chicxulub crater is only 150 kilometers wide at the Yucatan peninsula.. 

    At one time, there was no Caribbean Sea. South America and Africa were joes into Gondwanaland and North America and Europe formed Laurentia. Further back in time all the continents were joined together to form Pangaea. There was no Caribbean or Gulf of Mexico or Atlantic Ocean

    There still is.  It's just underwater.  I do believe, though, that there is a theory that it is actually a giant crater that was created by the asteroid that killed the dinosaurs, explaining its wide and uniform shallowness and the fact that its periphery appears concentric.  But then the Gulf of Mexico is also extremely shallow and even more concentric, so two asteroids?

    At any rate, the shallowness of the Carribean and the Gulf of Mexico is key to global weather.  The shallowness makes it extremely easy for the sun to heat it, making it an unusually warm body of water.  That warmness is what creates the Gulf Stream, which flows north and warms Europe, keeping it from being as cold as it should be for as north as it is.  That warmness is also the engine for the strongest and most frequent hurricanes in the world.
