Mabul, Sipadan: Macro haven near a diving icon

Mabul is an island located roughly 15 kilometres from Sipadan, offering a distinct dive experience. While Sipadan is known for pelagic action, Mabul is a destination prized for its abundant macro life and 'muck diving' potential. The island itself is largely flat and oval-shaped, spanning about 20 hectares, with sandy beaches that transition directly into dive sites, many accessible from the jetties, such as the Awas site just off the Scuba Junkie jetty.

The diving here is focused on observation, moving slowly over sandy or silty bottoms and artificial reefs. These artificial structures, along with the natural reef and sandy flats, create diverse habitats for small, cryptic creatures. Depths are generally shallow, allowing for extended bottom times to meticulously explore these environments, which is ideal for photographers seeking out rare species. You'll find yourself adjusting your buoyancy to hover just above the substrate, scrutinising every cranny.

Mabul's reputation is built on its exceptional collection of marine invertebrates and tiny fish. Green sea turtles (Chelonia mydas) are a regular sight, often found resting or feeding on the reef. Beyond the larger species, the real draw lies in observing creatures like broadclub cuttlefish (Sepia latimanus), various frogfish, and ghost pipefish subtly blending into their surroundings. These often require a keen eye and patience to spot, rewarding careful observation.

The site hosts a notable variety of cephalopods; you can encounter flamboyant cuttlefish (Metasepia pfefferi) displaying their pulsating colours, mimic octopuses, and bobtail squids (Sepiolidae) partially buried in the sand. Blue-ringed octopuses (Hapalochlaena) are also present, adding to the allure for macro enthusiasts, but always remember to observe these with respectful distance due to their potent venom.

Other frequent discoveries include various nudibranchs, ranging in shapes and colours, along with mantis shrimp (Odontodactylus scyllarus) guarding their burrows. Keep an eye out for pipefish, snake eels, and exotic starfish. The sand and rubble areas around the jetties often yield additional rare finds, showcasing the diversity present in what might initially appear as barren ground.

Conditions at Mabul are generally calm, contrasting sharply with the potentially strong currents of nearby Sipadan. This low-current environment is ideal for focusing on minute details and allows for relaxed, unhurried dives, which is crucial for macro photography and patiently waiting for subjects to reveal themselves. While the reef itself may not be as vibrant as some offshore sites, the sheer variety and density of small marine life more than compensate for it.
