Researchers from Australia studied epaulette sharks from the Great Barrier Reef
This species lays eggs that are left unprotected for four months before hatching
The team explored the impact of increasing water temperatures up to 87.8°F
Warmer conditions cause the embryos to grow faster and use up their yolk sac
This meant the hatchlings emerged earlier and weaker than they would normally
Temperatures on the Great Barrier Reef are expected to hit 87.8°F this century
