Dinoflagellates are symbiotic with ________ |
Corals called Zooxanthellae |
|
|
|
What type of phytoplankton are responsible for harmful algal blooms and some bioluminescence? |
Dinoflagellates |
|
|
|
Coral Bleaching is a result of |
Loss of Zooxanthellae due to increased sea surface temp & increased acidity (lower PH) |
