How Warming Oceans affects Metabolism of Sharks?

11 March 2021.


 In a recent study, it has been found that, the warming of worldwide oceans due to climate change may affect the metabolism of sharks. The scientists conducted the work in the New England Aquarium and studied “Epaulette Sharks” which live off the Australia and New Guinea.

Highlights of the study:

  • In the recent study, the scientists have found that warmer conditions have boosted the growing process of Sharks.
  • It means that; these sharks hatched from the eggs earlier and were born exhausted.
  • The scientists also found that the baby sharks were at the risk of being born smaller.
  • They would also be born without energy they require to survive.
  • The scientists performed the study using breeding program for sharks by the aquarium.
  • The scientists first raised 27 sharks under the average summer conditions or in about 27℃.
  • They were also kept under the temperature of about the 29℃ and 31℃.
  •  It has been found that the sharks reared in warmest temperatures weighed less than those who were raised in the average temperatures.
  • They also exhibited the reduced metabolic performance.

About Epaulette sharks

  • The shark comprises of a very large, white-margined black spot behind each of the pectoral fin.
