Great Barrier Reef has sort of chlamydia

The discovery of chlamydia-like bacteria in corals of the Great Barrier Reef could help scientists understand the coral microbiome and its impact on coral reef health.

Corals are associated with a variety of bacteria, which occur in the surface mucus layer, gastrovascular cavity, skeleton and tissues where they play a critical role in protecting corals against pathogens, cycling nutrients, and producing vitamins and essential amino acids. 

Some tissue-associated bacteria form clusters, termed cell-associated microbial aggregates (CAMAs), which are poorly studied.

People commonly say that experienced divers should guard against complacency, but what does that mean? Some associate the idea of complacency with arrogance, carelessness or negligence, and reassure themselves that if character traits such as these do not apply to them, then they do not have to worry about being complacent.
