The research team found that shark embryos grow faster in warm waters, and the yolk sac (which is their only food source at this stage of development) can be used more quickly.
Researchers from James Cook University and the University of Massachusetts’s Centre of Excellence for Australian ARC Coral Reef Research said on Tuesday that these hatched creatures hatch earlier and are smaller at birth. They need to forage immediately but lack energy.
There are more than 500 kinds of sharks living all over the world, most of them are young sharks. Some sharks, such as the epaulette shark, lay eggs, which are not protected and must be able to live alone for four months.
Jodie Rummer, co-author and associate professor of the ARC Centre of Excellence for Coral Reef Research, said in a statement: “The epaulette shark is known for its ability to change and even acidify the ocean.” “Therefore, if the species can How will the less receptive species survive?”
The Great Barrier Reef is the largest coral reef in the world, covering nearly 133,000 square miles. It is home to more than 1,500 species of fish, 411 species of hard corals and dozens of other species.
Rumer said that rising ocean temperatures may threaten future sharks, including spawning and living species, because as the temperature rises, these creatures will be born or hatched into an almost intolerable environment.
Lead author Caroline Wheeler said in a statement: “Given that sharks are already under threat, this study presents a worrying future.”
“Sharks are important predators to keep the marine ecosystem healthy. Without predators, the entire ecosystem would collapse. That’s why we need to continue to research and protect these creatures,” Wheeler, PhD candidate, ARC Coral Reef Research Center of Excellence Added. .
Lenmo said: “Our future ecosystem depends on (us) taking urgent action to limit climate change.”
The research was published in the journal Scientific Reports.
Warmer oceans also lead to increased rainfall and lead to stronger and longer lasting storms such as hurricanes Florence and Harvey.
A landmark report discovered by the United Nations Intergovernmental Panel on Climate Change in 2019 showed that the frequency of ocean heat waves that killed large tracts of coral reefs on the planet may have doubled and is expected to become more common and intense.
CNN’s Jen Christensen, Ivana Kottasová and Drew Kann participated in the report.
