Why is there no plankton in the Caribbean?
Why is there no plankton in the Caribbean? Because the tropics have warm surface water, even in the winter, the thermocline never goes away, and the nutrients stay trapped down below in the depths. So even with ample sunlight, phytoplankton growth is severly limited. In the tropics, predators like coral make good use of what little plankton there is.
Do sharks swim in the Caribbean?
