The rulebook that sits under every snorkel and dive — no standing, no chasing, no souvenirs, and why parks now say it in five languages. Reef etiquette is the shared conduct layer for snorkeling, scuba and freediving on living coral and in seagrass. It is written by parks, customary owners and a few national statutes — not by a training agency’s marketing slide.
The skill ceiling is low on purpose: the rules are simple and the failures are expensive in centuries of coral growth. Accessibility is high because anyone who can enter the water can also choose not to kneel on a colony. This chapter is not a live briefing and not a permit. Local rangers, mooring fees and seasonal closures override any atlas sentence.

Many parks specify 2–3 metres or more, no blocking the surface path. If the animal changes direction, the person is too close. Pacific rahu and similar closures are older than tourism. The printed “do not stand on coral” card is a late-twentieth-century park product, written after the first mass-snorkel bays failed.
Seasonal closures and species taboos in Polynesia, Micronesia and elsewhere — conservation as law, not a brochure. The practice is a pre-brief, a horizontal body, and a default no. Duck-dives and cameras are optional; touching is not a skill to “get good at.”
