Bubble Coral Shrimp – Vir philippinensis
Like all coral associated shrimps, the limit between, parasitism and mutual symbiosis, is pretty thin. Probably that the shrimp, in exchange of food and shelter, helps fight off some small parasites, such as flat worms, coral eating nudies, some sponges or algae that would compete with the corals. or even clean the coral off any detritus, sand…
Bubble Coral – Plerogyra sinuosa
The vesicles resembling bubbles up to 1 in in diameter. These enlarge during the day but retract to a certain extent during the night to expose the polyps and their tentacles. It obtains most of its nutritional needs from the symbiotic dinoflagellates that live inside its soft tissues including the walls of the vesicles. These photosynthetic organisms provide the coral with organic carbon and nitrogen, sometimes providing up to 90% of their host’s energy needs for metabolism and growth. Its remaining needs are met by the planktonic organisms caught by the polyps at night.
