There are 15 species of snapping shrimp in the Atlantic Ocean and 15 species of snapping shrimp in the Pacific Ocean. Some of the species live in shallow water while others live in deeper water. The Atlantic and Pacific oceans are separated by the Isthmus of Panama. Geological evidence shows that the Isthmus of Panama started rising about 10 million years ago, completely separating the two oceans by about three million years ago.

Design a plan for collecting the data that you would need to determine whether reproductive isolation has led to speciation.
