Dive the Lembeh Strait

Aer Perang

The formation of this Lembeh Strait dive site was influenced by a World War II warship that blasted through the rocks in order to reach fresh water. The name literally means 'War Water'.

It is a relatively shallow sand slope that is home to many rare species of octopus. Finding them hidden in nooks and crannies or under the sand takes some skill due to their expert ability to camouflage themselves. The mimic octopus in particular can change colour, shape and even the texture of its skin to blend in with their surroundings, and often they can be spotted here.

An encounter with a wonderpus is even more unique as this species is endemic to Indonesian waters. It is very similar to the mimic octopus, but has well-defined white spots on the mantle, and bars on the arms.

While waiting for the octopus show to start, you may notice pairs of Pegasus seamoths using their pelvic fins to 'walk' along the bottom in search of worms and small prey. Recently, a hole at a depth of 15 metres has become home to a pair of rhinopias. The jury is still out as to whether they are the common red type, or the more rare pink variety. You might want to have a look to decide for yourself.

The calm conditions make this the ideal place to enjoy your first night dive in Lembeh where you will see stargazers peeking out at you from the sand with just their eyes and mouths showing. Aer Perang is an excellent site if you want to dive the Lembeh Strait and a must for all lovers of cephalopods.
