Site Overview

Rhodas Reef is a gentle sloping hard-coral garden on the West Coast of Christmas Island that is widely regarded as one of the best macro photography sites on the island. The reef slope at three to fifteen metres depth features healthy hard coral formations including branching staghorn corals, plate corals, and diverse soft coral communities that provide habitat for an extraordinary variety of small and cryptic marine species. Ghost pipefish drift among the soft corals and sea fans with their remarkable camouflage perfectly mimicking the surrounding environment while frogfish perch motionless on the coral branches waiting to ambush unsuspecting prey. The elusive ribbon eel extends its colourful head from burrows in the sandy areas between coral formations providing one of the most sought-after macro subjects in tropical diving. Diverse nudibranch species are abundant on the reef with numerous chromodorids, aeolids, and other colourful varieties providing endless subjects for macro photography. The calm conditions and gentle slope allow extended bottom times ideal for patient searching and careful composition of macro photographs without the pressure of strong currents or depth limitations. Pipefish of various species drift through the coral branches alongside their ghost pipefish relatives creating fascinating comparative observation opportunities. The combination of pristine coral health, exceptional macro biodiversity, and calm accessible conditions makes Rhodas Reef a must-visit destination for underwater photographers and marine naturalists exploring Christmas Island.

Dive Briefing

"Descend from the boat to the reef slope at approximately five to eight metres and begin a slow methodical search pattern along the coral-rubble interface where cryptic species are most concentrated. Move slowly and deliberately examining each coral head, soft coral cluster, and sandy patch for ghost pipefish, frogfish, and other macro subjects. Ghost pipefish are most commonly found drifting among the soft corals and sea fans where their elongated body shape and colouration perfectly mimics the surrounding environment. Frogfish can be found perched on coral branches and rubble surfaces using their modified fins to grip the substrate while waiting for prey to swim within striking distance. Ribbon eels inhabit burrows in the sandy areas between coral formations and can be identified by their colourful heads protruding from the substrate with their mouths gaping open. Nudibranchs are most visible on the upper surfaces of coral bommies and on the reef flat where their vivid colours contrast with the substrate. The shallow depth allows very long bottom times so take advantage of the extended dive duration to thoroughly explore every micro-habitat across the reef slope and discover the full diversity of this remarkable macro paradise."
