“An increase in metabolic rates means that sharks are using more energy to just be alive and swim,” Di Santo told CNN. Some fish species are not able to find new, suitable habitats, which causes a decline in their population. “It is important to consider that sharks are very much tuned in the behavior of their prey,” Di Santo said. “These small-scale movements can be just as crucial for their survival as poleward relocations,” Di Santo said. Zidowitz said progress on conservation to protect shark species is “too slow to keep pace” with the numerous threats they face, yet she remains hopeful.
