When bleaching happens, corals lose their zooxanthellae
, the algae that lives inside them in symbiosis or a mutually beneficial relationship.
, sourced equally from sacrificed adult Tridacna maxima and T.
Exploring Anything above 30degC causes the organisms to expel their zooxanthellae
algae, leaving behind a frail white skeleton, a phenomenon known as coral bleaching.
Changes in zooxanthellae
densities and chlorophyll concentrations in corals during and after a bleaching event.
Corals and microscopic algae called zooxanthellae
, have a mutually beneficial relationship where the tine algae gain shelter, carbon dioxide and nutrients while corals get photosynthetic products that can provide them with up to 90% of their energy needs.
In addition, increased concentrations of nutrients can cause an imbalance in the relationship between zooxanthellae
(endosymbiotic dinoflagellates - Symbiodinium spp.
The photosynthetic zooxanthellae
provide up to 90 per cent of the energy the corals need to grow and reproduce, while also giving them most of their colour.
Coral bleaching occurs when water temperatures rise, causing the corals to expel the algae zooxanthellae
, which then turns the coral to turn entirely white.
This may affect the development and survival of zooxanthellae
and/or coral, because they use nitrogen for nutrients production.
Coral polyps provide a perfect protective home for tiny zooxanthellae
Dejucos said most corals live in a symbiotic relationship with photosynthetic algae called zooxanthellae
, which lives inside their tissue.
Three interesting exhibits are the zooxanthellae
(or "zoox"), plantlike organisms that live inside coral polyps, gobbleguts, a type of cardinal fish, and the anemonefish--can you find 'Nemo'?
