The salmon: a beautiful symbol of the iconic fishing industry in Maine. The perfect victim for climate change. As a creature with a migration based life cycle, it is vulnerable to the water temperature altering effects of a warming climate. If its home up north grows too warm, the salmon may have to relocate its ancestral breeding grounds further south, leaving commerce and the population decimated for generations to come.
As ice flows melt and the ocean gradually rises, certain species of fish will find deeper, cooler water, away from the warmer, more acidic surface of the ocean. This will result in certain species being decimated by predators better suited to the new climate, or poor birth rates because of a change in incubation temperature.

Some animals whose ecosystems are based around coral or the integrity of an exoskeleton (like the common crab) are vulnerable to the increased pH levels associated with climate change. Increased pH leads to calcification of coral or the essential parts of the shell, weakening natural defenses against the elements or predators (respectively). In addition to the common practice of overfishing, species can be easily driven to extinction in a matter of years.
