Dive profile & how the dive runs

A typical dive at Alimatha Reef often focuses on the main reef structure, especially during night dives. Entry is usually via a boat drop, allowing for a direct descent to the productive areas. The dive route generally follows the reef, moving at a relaxed pace due to the mild currents. Depths are typically shallow, averaging around 13 meters, which allows for longer bottom times and extended observation of the marine interactions. The main attraction is the predictable presence of nurse sharks and stingrays, particularly active after sunset. Divers are encouraged to maintain good buoyancy and observe these animals from a respectful distance. The dive concludes with a gradual ascent, and the safety stop is typically performed in open water above the reef before surfacing for boat pick-up.

Underwater photography

Alimatha Reef is a prime location for capturing unique nocturnal marine encounters, specifically with nurse sharks and stingrays. For wide-angle photography, consider a fisheye or wide-angle lens to frame the dynamic interactions of multiple sharks and rays. Strobes are essential to illuminate subjects and restore natural colors in the low-light conditions of a night dive. Be mindful of not overpowering your subjects with excessive flash, which can disturb their natural behavior. For close-up shots of individual animals, a macro lens may also be effective. Maintaining excellent buoyancy is crucial, especially at night, to avoid disturbing the sand or the animals.
