Erg Iris, Soma Bay: a vibrant Red Sea erg dive

Dropping into Erg Iris, divers will immediately appreciate its gentle yet vibrant character, defined by an array of small ergs and substantial coral blocks. This isn't a single, continuous wall but rather a decentralized landscape, where a large, easily navigable coral formation rises impressively from the seabed, offering a clear dive profile. Its sheer size and scattered nature mean there's ample opportunity to explore its contours and numerous passages, discovering new facets with each fin stroke.

The dive profile at Erg Iris remains relatively shallow, reaching a maximum depth of 14 metres, making it accessible for various certification levels and allowing for extended bottom times. This provides ample opportunity to thoroughly investigate the intricate nooks and crannies of the coral structures. While the depth is modest, the topography offers a sense of adventure, requiring a developed sense of orientation to navigate among the scattered formations and ensure exploration of the most interesting areas.

As divers make their way around the erg and weave through the coral maze, they'll find themselves gliding through areas that are veritable nurseries for young fish, creating dynamic, shimmering canvases. Beyond the bustling life of juvenile fish, Erg Iris holds pleasant surprises for the observant diver, including the aptly named hatchetfish (Poissons-hachettes), which often blend seamlessly with their surroundings.

Keep an eye on the open water, as Erg Iris often surprises divers with its mobile residents. Majestic eagle rays (Aetobatus narinari), with their broad, wing-like pectoral fins, are known to glide gracefully through the blue, appearing as if from nowhere. Dolphins (dauphins) have also been frequently observed here, gracing divers with their playful presence, adding an element of wild magic to the underwater journey.

Beyond the powerful presence of eagle rays and dolphins, Erg Iris is a regular haunt for sea turtles, including green sea turtles (Chelonia mydas) and hawksbills (Eretmochelys imbricata), often seen grazing on algae or resting among the coral. The scattered nature of the ergs and blocks fosters hidden communities of reef fish and invertebrates, urging divers to slow down and observe closely. Each turn around a coral formation reveals a new tableau, making the dive consistently engaging for those who appreciate the subtle beauty of a well-developed reef.
