AI Summary

Scientists have identified chemosynthetic bacteria on the gills of coral reef fish, a first for fish hosts. The bacteria possess genes that enable them to convert inorganic compounds into organic molecules, a process known as chemosynthesis. The gill microbiome is described as complex and specialized, though its functions remain poorly understood. Researchers suggest the bacteria could influence fish metabolism, immunity, and overall health. Further study is needed to clarify the role of these microbes in fish physiology.
