Biologically, the Sea of Cortez is one of the richest bodies of water on the planet and has rightly earned the epithet of the “world’s greatest fish trap.” With over 900 different kinds of fish (around 20% of which are endemic) and 2000 kinds of marine invertebrates to be found in its waters, the Sea of Cortez is truly swimming with life. Indeed, one of the reasons the Sea of Cortez is filled with fish is its abundant food supply.
Though this body of water is too small to have its own lunar tide, it does produce a strong tidal flow also impacted by those of the Pacific Ocean. Due to a collision of currents and other factors such as the contour of the bottom of the sea, the Sea of Cortez experiences an interesting “whirlpool” effect that circulates lots of nutrients, plankton, and sea life. There’s always plenty of eating to be found in the Sea of Cortez, and as such there are always plenty of happy fish. Of course, that means there’s also plenty of happy fishermen.
