Happy #WorldTurtleDay 🐢

A few of my favorite sea turtle encounters from dives around the world — calm, graceful, and always unforgettable subjects underwater.

A tiny orange frogfish hiding in plain sight. One of the strangest little ambush predators on the reef.

Muck-diving magic 🐍✨ Spotted a crocodile snake eel on a night dive and captured this stealth predator in action.

#Mandarinfish are tiny, shy, and ridiculously bright. Most of the day, they hide deep in the coral, then at dusk they sneak out for a quick, blink-and-you-miss-it courtship ritual.

The Mighty Crocodile Snake Eel

The crocodile snake eel burrows into the sand with only its eyes and snout showing. It looks more like a lurking myth than a real animal. I first met this unusual eel while diving near Siladen Island, Indonesia. It was on a sandy slope where the reef faded into open water. What seemed at first like a random bump in the sand slowly turned into a pair of watchful eyes and a crocodile-like head.

Crocodile snake eels (Brachysomophis crocodilinus) are classic ambush predators. They spend much of their time buried, waiting for fish or cephalopods to wander just a bit too close. For macro-loving divers and underwater photographers, finally spotting one feels like cracking a secret code in the sand.

The crocodile snake eel belongs to the family Ophichthidae. This family includes worm and snake eels known for their elongated bodies. They also exhibit burrowing behaviour. Adults can reach impressive lengths, with males documented up to around 120 centimetres. Their common name comes from the crocodile-like shape of the head. The head has a long snout and strong jaws. Its eyes are positioned high on the head. The body is typically mottled or patterned to blend in with sand, rubble, or coral debris.

Rather than actively chasing prey, the eel waits in place until a small fish or octopus comes within striking distance. Then, with a rapid lunge, it grabs its meal and retreats back into the sand. For divers, the best approach is to move slowly over sandy patches. Divers should scan for eyes or a snout protruding from the seabed rather than looking for a fully swimming eel.

Thanks to the dive guides at Siladen Resort and Spa for pointing out the bright orange eel in the sand.

Crocodile snake eels are generally considered harmless to humans. They are ambush predators that focus on small fish and cephalopods rather than large animals. Most of the time they remain buried in the sand with only the head showing, and they prefer to stay hidden rather than confront divers. As with any wild animal, giving them space and avoiding physical contact is the best approach.

Scientific references place crocodile snake eels at depths from the intertidal zone down to around 30 metres, with many observations in very shallow water, roughly 0–2 metres. They tend to favour sandy or rubble areas near coral reefs where they can dig burrows and wait for passing prey. For divers, this means they can be encountered on shallow lagoon dives, sand slopes, and reef outskirts rather than only on deep drop-offs.

Crocodile snake eels are part of a wider Indo-Pacific distribution that includes Indonesia, East Africa, the Society Islands, Japan, and Australia. In Indonesia, divers often report them on sandy slopes and lagoon areas near islands such as those around North Sulawesi, where sand and rubble zones sit beside healthy coral reefs. Slow, careful exploration of these habitats gives you the best chance of spotting their distinctive eyes and snout protruding from the sand.

Night Diving in Komodo

Night diving in Komodo National Park, Indonesia reveals a completely different side of the reef. Species that remain hidden during the day emerge to hunt, feed, and interact in ways that are rarely seen under daylight conditions. What looks like a calm reef during the day becomes active and unpredictable after sunset.

This dive log captures several night dives in Komodo, where the focus shifts from wide-angle reef scenes to macro life, nocturnal predators, and unusual behaviors. For divers and underwater photographers, night diving here is less about big animals and more about discovering species that are often missed entirely during daytime dives.

I spent a week aboard the Indo Aggressor, based in the Indonesian city of Labuan Bajo. During the week at sea, guests were offered daily night dives. I dived each night and saw many unique critters and interesting behavior underwater. The video below highlights some of the cool moments during our night dives.

Marine Life You Can See on a Komodo Night Dive

Night diving in Komodo is primarily about macro and behavior-focused encounters. Many of the species observed during these dives are rarely seen in daylight or behave completely differently after dark.

Common sightings include:

• Decorator Crab
• Bigfin Reef Squid
• Painted Frogfish
• Blue-Spotted Stingray
• Spotted Flathead (Crocodilefish)
• Needle Cuttlefish
• Stingray vs. Cuttlefish
• Spanish Dancer (Super Large Nudibranch)
• Komodo Reef Octopus
• White-Spotted Hermit Crab
• Whitemargin Stargazer
• Broadclub Cuttlefish
• Lacy Scorpionfish (Rhinopias)
• Bigfin Reef Squid

Some dives may also reveal nudibranchs, flatworms, and other small invertebrates moving across the reef. The slower pace of night diving makes it ideal for spotting these smaller subjects.

Dive Conditions and Safety Considerations

Night diving requires a different mindset than daytime diving, especially in a place like Komodo. While currents are generally reduced at night, divers still need to be aware of changing conditions, entry points, and navigation limits.

Key conditions:

• Depths: 20–60 feet (6–18 meters)
• Water temperature: 79–84°F (26–29°C)
• Visibility: 30–50 feet (9–15 meters)
• Current: Mild to moderate depending on site

Divers should carry at least one primary dive light and a backup. Maintaining close proximity to the guide is critical, as visibility is limited to your torch’s beam. Good buoyancy control is especially important to avoid disturbing marine life or damaging coral.

Best Time of Year for Night Diving in Komodo

Night diving is possible year-round in Komodo National Park, but overall conditions vary by season.

• April to November (Dry Season):
  Best overall conditions with calmer seas and more predictable diving
• December to March (Wet Season):
  Increased plankton and nutrients can improve marine life activity, but surface conditions may be less stable

Because night dives are typically conducted in sheltered areas, they are less affected by wind and waves than daytime dives. This makes them a reliable option even when daytime conditions are marginal.

I previously posted a few exciting moments during the entire dive trip here. Also, I posted a few photographs from the trip here. In a few weeks, I will post my travel and liveaboard trip report.

I find night dives interesting because you can see animals that you don’t see during the day. Below is a video playlist that hosts a few more night dives from around the world. There are a few interesting clips from Roatan, St. Kitts, Raja Ampat, and the Bahamas.

FAQs

Night dives in Komodo commonly reveal octopus, moray eels, decorator crabs, boxer crabs, nudibranchs, cuttlefish, and hunting lionfish, many of which are rarely active during the day.

Yes, most night dives in Komodo are conducted in protected, shallow sites with mild currents, typically between 30 and 80 feet, making them suitable for divers with basic experience and good buoyancy control.

Night diving is available year-round, but April through November offers the most stable conditions, while December through March may provide increased marine life activity due to higher nutrient levels.
