Canons is a relaxed boat dive in the Cocos (Keeling) Islands, often done as an easy afternoon outing after lunch. The site is known for regular dugong sightings and may also draw dolphins and manta rays moving through the lagoon. Sandy patches and the undersides of ledges are the main terrain features, with garden eels on open sand and gobies sheltering in finer sediment. It is a simple, marine-life-focused dive that is best approached as a calm, low-stress lagoon trip rather than a big-structure reef dive.
