Acropora

Ooh no I didn't realise they'd added a coral reef mission! Thanks Elsa, I'll go ahead and add them all! I have some other Hoga pics I need to put up too, as well as more from my trip!

Kind of, xiang! Those white tips are the growing tips. The calcium carbonate skeleton gets laid first as the coral grows, then the algae that live within the coral move in. It's the algae that give the coral its colour, so that's why the tips appear white. So it's kind of the same principle with coral bleaching, heat stress makes the coral lose its algae so it appears white, hence the name coral bleaching! This one is healthy though :)

Thank you both :)
