Marlin Fishing From Cabo

Thought I would share this from Cabo:

Once we got to the area you could instantly see the Striped Marlin jumping out of the water as they hunted their prey. It took only a matter of minutes for us to have two fish on.

Learned something new.

Striped marlin in Cabo are like white bass in rivers in the spring. Tons of them.
After three or 4 trips you tell the charter boat guys to find something different to catch.

What prey were the marlin looking to find as they lept from the water to find and then eat it upon crashing back into the water?
