Scientist have recently frozen the Great Barrier Reef coral in world.



  • Scientists used the cryomesh to freeze coral larvae at the Australian Institute of Marine Sciences (AIMS).
  • The Great Barrier reef coral has suffered four bleaching events in the last seven years including the first ever bleach during a La Nina phenomenon.


What is Cryomesh?

  • Cryomesh is a specially fabricated mesh used as substrate in cryopreservation. This is lightweight and can be manufactured cheaply. It better preserves coral and has the properties of cryoplates.
  • The mesh technology will help store coral larvae at -196°C (-320.8°F).


Significance of Coral Cryopreservation 

  • Cryogenically frozen coral can be stored and later reintroduced to the wild. This could eventually help to rewild reefs threatened by climate change.
  • It can build a bigger, more diverse bank of frozen living corals, preserving biodiversity.


What are corals?

  • Corals are animals which live in a symbiotic relationship with microscopic algae called zooxanthellae (which live within the coral tissue).
  • The zooxanthellae convert sunlight into food, providing corals with up to 90 per cent of their energy needs. They also give corals much of their colour.
