Muck diving involves exploring sandy bottoms, silt, or coral rubble rather than pristine coral gardens. It may sound unappealing, but it is like an underwater treasure hunt. This environment is where you find exotic species such as Flamboyant Cuttlefish, Blue-Ringed Octopus, Mimic Octopus, Ghost Pipefish, and countless unique Nudibranchs that you will not see on conventional reefs.
