Muck Diving at Lembeh

K2 Lembeh Resort Muck Diving Exotic Critter Squat Lobster

Welcome to the world’s macro capital. Lembeh’s black‑sand slopes and coral rubble hide rare, remarkable marine life—from flamboyant cuttlefish and mimic octopus to hairy frogfish and blue‑ring octopus.

Unassuming habitats — black sand, silt, rubble — nothing there?

No! This is where the masters of camouflage live — hiding in plain sight!

You search slowly with trained eyes (and expert guides) for rare, cryptic creatures. Expect a relaxed pace, shallow profiles, and long bottom times perfect for macro photography.

What is Muck Diving?

Masters of Camouflage

Hi! My name is yonemichthys rumengani and I am a Lembeh Sea Dragon!

I am about 2.7cm or 1 inch long, I am usually with my mate, attached to growth on walls or on silty sand. You will have to look very hard to find me, usually what gives me away is the graceful movements that characterize the motion of a living organism. Oh don't worry, K2 Lembeh Dive Resort's guide will spot me for you to see. Ah, but if you want to photograph me, you need lots of patience!

Muck Diving

Why it’s special

You’ll find species most divers never see—living behaviors, courtship, hunting—right before your eyes.

Slow shallow dives

Slow, deliberate, 5–25 m depth, torches & pointers for positioning (never for touching).

Is it for you?

Are you thrilled with discovering hidden critters? Watch it hunting, seeing its underwater behavior? Maybe photographing them?
