If there is too much light, their photo systems break down and they produce these oxygen compounds that cause stress to the coral animal
The coral animal
and the associated zooxanthellae depend on each other for survival in a symbiotic relationship, where the coral supplies the algae with nutrients and a place to live.

As each coral animal
grows, it attaches its skeleton to others around it, so the skeletons are cemented together.
At their most basic level, corals are a marriage between tiny coral animals
and a plant living inside them called zooxanthellae.
The unique assemblages of tiny coral animals
and symbiotic plants provide habitat for as many as 1 million species-including more than a quarter of known marine fish species.
The report focuses on the process of coral bleaching, whereby stressed coral animals
expel the microscopic plants that give them color causing the coral to turn white and often die, due to slight increases in ocean temperature.
Mass coral-bleaching events, caused by a breakdown in the relationship between the coral animals
and their symbiotic algae, are strongly correlated with unusually high sea temperatures and have led to widespread reef degradation in recent decades," explained lead author Dr James Guest, currently a joint research fellow at the UNSW Centre for Marine Bio-innovation and the Advanced Environmental Biotechnology Centre at Singapore's Nanyang Technological University.
By embodying the coral reef, they grasped the ways in which coral animals
Coral reefs are built up of thousands of small coral animals
that live in a large colony which forms a common limestone skeleton.
They use sunlight to make food for the coral animals
in exchange for a stable scaffold to dwell in.
Bleaching occurs when warmer ocean temperatures or other environmental changes agitate the microscopic algae (or zooxanthellae) that inhabit the tiny coral animals
that make up the reef.
