The stable symbiotic relationship between corals and their algae symbionts (mainly dinoflagellates) is crucial for the survival of tropical and subtropical coral reef ecosystems. Through photosynthesis, these algae provide over 90% of the nutrients corals require, meeting their essential nutritional needs.
Symbiodinium trenchi is a stress-tolerant species and is able to form mutualistic relationships with many species of coral. It is present in small numbers in coral globally and is common in the Andaman Sea , where the water is about 4 °C (7 °F) warmer than in other parts of the Indian Ocean .
Coral and microscopic algae have a symbiotic relationship. When water temperatures get too high, the algae leave the coral tissue and the coral begins to starve. [20] Climate change will affect coral reef ecosystems, through sea level rise, changes to the frequency and intensity of tropical storms, and altered ocean circulation patterns.
The type of marine animal vary greatly, for example, sponges, sea squirts, corals, worms, and algae all host a variety of unique symbionts. [5] Each symbiotic relationship displays a unique ecological niche, which in turn can lead to entirely new species of host species and symbiont. [3]
The relationship between jellyfish and zooxanthellae is affected a little differently than coral in terms of climate change despite both of them being a part of the cnidaria family. [23] One study suggested that certain species of jellyfish and their symbiotic zooxanthellae may have some type of resistance to decreasing pH caused by climate ...
In this relationship, the algae provides the coral with a Carbon source to develop its CaCO 3 skeleton and the coral secretes a protecting nutrient-rich mucus which benefits the algae. Perhaps one of the most famous discoveries made by Muscatine in the field of trophic mutualism came about 10 years later in another aquatic based system-the ...
Bleached colony of Acropora coral. There is a symbiotic relationship between coral polyps and the photosynthesising algae called zooxanthellae, without which, neither would survive. When sea surface temperatures exceed approximately 29 °C or more, even for a couple of days, the relationship between the coral and its zooxanthellae becomes ...
Symbiotic Symbiodiniaceae are sometimes colloquially referred to as Zooxanthellae, though the latter term can be interpreted to include other families of symbiotic algae as well. [7] While many Symbiodiniaceae species are endosymbionts, others are free living in the water column or sediment.
