多物种珊瑚礁鱼群：泰国海域的羊鱼与鲷鱼混合游弋

l of yellowfin goatfish merges with a school of two spot snapper (Lutjanus biguttatus) over an Indo-Pacific coral reef, the two species mixing into a single moving mass of silver and yellow fish. Mixed-species schooling like this is a common reef fish strategy, thought to reduce individual predation risk by increasing the overall size and visual complexity of the group. This kind of multi-species aggregation reflects the dense biodiversity supported by healthy Andaman Sea reef structure. Andaman Sea, Krabi Province, Thailand.
