One change that might benefit jellyfish in their competition with anchovies and predation by tuna and swordfish is an increase in their reproductive rate. If jellyfish are able to reproduce at a faster rate, they can potentially outcompete anchovies for limited plankton resources. Additionally, a higher reproductive rate could help offset the predation pressure from tuna and swordfish, allowing jellyfish populations to maintain or grow. This change could give jellyfish an advantage in terms of population size and survival.
