Coral Reef in Lembeh Strait
Critters at Lembeh Resort


The Lembeh Strait is known for offering the best muck diving and underwater photography in the World. The abundance of rare and unusual critters is unparalleled.
Explore this unique region with Lembeh Resort.

Muck diving is at its best in Lembeh, where the sheer abundance of biodiversity and unique critters is greater than it is anywhere else on Earth. Every dive reveals countless special finds – often where you might least expect them. The excitement in muck diving lies in finding rare, camouflaged and breathtakingly beautiful (and often ugly) critters. For beginners, the marine life found by your guide is simply intriguing, unique and downright weird all at once. Experienced divers will feel the exhilaration of making “special finds” for themselves and a rush of adrenaline that can’t be matched. For underwater photographers, a great photograph speaks many millions of words.

Muck diving offers something for everyone and it develops an unparalleled attention to detail like no other style of diving can: With nothing to distract, the smallest of details begin to surface. That’s why when we muck dive we go at a slow pace and look to find the most camouflaged and often smallest of critters. Slow and relaxed diving also offers you the opportunity to observe and photograph the wondrous marine life that our expert-trained dive guides are so adept at finding.

We spend quite a lot of time between 18-22 meters (60-75 feet) so Nitrox is ideal and PADI Enriched Air Nitrox courses are available on-site.

The best muck diving sites are characterised by black, volcanic sand slopes which are littered with natural debris – which creates hotspots for hiding critters. We also have many combination dive sites within minutes of the resort that offer the best of muck diving together with beautiful, shallow water coral reefs. These dive sites are where we tend to find pygmy seahorses, numerous species of anemonefish and the endemic Banggai Cardinalfish.

The Lembeh Strait is located in the heart of the Coral Triangle in Indonesia so for those who’d like to explore or combine coral reefs into their trip we have some of the most pristine reefs on Earth. Take a look below at some of coral reef diving locations.

Within minutes of Lembeh Resort there are a host of both black sand and grey or white sand sites. You’ll find that the critters across these sites differentiate and at Lembeh Resort we are one of the only operators to really distinguish between these  diving locations.

Hairy Frogfish in Lembeh Strait

Did you know that you’ll never find a blue ring or a mototi octopus on a black sand dive site? These rich, black volcanic sands are home to hairy frogfish, numerous species of nudibranch, crustaceans and a wealth of Lembeh’s most iconic critters. Lembeh Resort’s dive guides are marine biology trained to understand where to find each critter. Air Bajo, Hairball, TK and ROJOS  are some of our favorite black sand sites which are packed with critters from start to safety stop.

Juvenile Puffer fish in Lembeh Strait

Our grey and white sand dive sites offer different critters to those found on black sand sites. There are few operators in Lembeh that recognise this distinction. Our in-house marine biologist and marine biology trained dive guides know which sites give you the best opportunities for specific species. Explore the grey and white sands of Pintu Colada, Pantai Parigi, Nudifalls, Bianca and Serana to discover unique finds and some of Lembeh’s most iconic critters.

Coconut Octopus

This incredible animal uses sea shells, coconut shells, glass bottles and other hollow items as a portable home. The coconut octopus are amongst the most inquisitive inhabitants of Lembeh Strait.

Mimic Octopus

The mimic octopus was discovered in the Lembeh Strait in 1998 and instantly surprised the scientific community with its unique behavioural traits. If threatened the mimic octopus can instantly change its behaviour, coloration and shape to mimic up to 16 other animals.

Starry Night Octopus

This elusive octopus lives on black sand sites and is only seen at night. Often found in shallow waters this rare species grows to an astonishing size of 80cm making it one of the largest types of octopus found in Lembeh Strait.

Mototi Octopus

This beautiful species is closely related to the much more famous blue ringed octopus and scientists believe that it carries a venom which is equally as potent. The mototi is often found hiding in discarded glass bottles or in the abandoned tubes of polychaete worms.

Blue Ringed Octopus

A highlight of diving in Lembeh Strait, the blue ringed octopus is only the size of a golfball. Its saliva packs one of the most powerful venoms known to man. With a the venom released in just a single bite a blue ringed octopus can kill up to 26 adult humans within a few minutes.

Wonderpus Octopus

This animal has the most suiting latin name: Wonderpus Photogenicus. The Wonderpus can show off electrifying color changes and is often found strutting around with its eight arms raised towards the surface.
