The effect of climate change on the predatory success of sharks

This literature overview focuses on how shark species, are faring with the anthropogenically induced climatic changes. The ocean is drastically affected by this, which has major implications on the aquatic life. Some effects include increasing temperature, carbon dioxide and acidity levels. This has led to shifts in the predatory success in sharks, which will only increase in severity as climate change intensifies, because changes in climate induce other changes in most aspects of the shark’s life. These can be grouped into three categories: shifts in body functions, behaviors and habitat. Some changes in body function include difficulty integrating sensory cues through reduced neuron receptor function, decreased brain/muscle aerobic potential and changes in growth/development. Behavioral changes include shifted swimming patterns, interacting with different species assemblages and prey behaviors. Lastly, habitat changes affect the shark’s ability to capture prey through increases in salinity, degradation of critical habitat and reduction in dissolved oxygen.
