Aer Bajo is something like the Prototype of a Black Sand Muck Dive: No Corals, no Reef, no Topography …just a Black Sand slope with some Debris and Garbage. A Muckdiving Lover would say: A Perfect place. Aer Bajo is situated on the Island side and faces north from a little headland sticking out into the strait. The divesite starts with a shallow flat at 5-7 meters from where it slopes down until 20-22 meters and then flattens out. Even though it is quite protected from strong current, it is still directly exposed to swell and waves at times and therefor naturally likes to collect all kind of debris: Wood, leaves, Bottles and various other things like Shoes, Clothes, Plastic Toys or Fishingnets. These items form the perfect little „islands“ for the critters on the sand of Aerbajo.
In this mix of very fine, almost muddy, sand with its little debris pools Mimic Octopus, Painted Frogfish, Hairy Frogfish, Seahorses, Flamboyant Cuttlefish, Longarmed Octopus, Coconut Octopus, Ambon Scorpionfish, juvenile Zebra Batfish and many different crutaceans and nudibranchs can be found. And in between the sightings of these critters Flounders, Dragonets, Gobies, Lionfishes, Various Scorpionfishes, Cuttlefish and Porcupine Fishes entertain the divers constantly.
Aerbajo can be dived almost always and only should be avoided when bigger swells come in from the north. Recommended lens is a 60mm or a 100mm Macro – for Mimic Octopus a fisheye lens can be used.
