Sexy Shrimp (Thor amboinensis) 🦐

Meet Thor amboinensis, the "sexy shrimp" — a tiny species reaching just 13mm, found across the Indo-West Pacific and parts of the Atlantic.

🎨 Olive-brown body decorated with symmetrical white patches, each outlined in fine blue lines.

🌊 Lives on shallow-water sea anemones and mushroom corals on reefs.

😏 The nickname comes from its signature move — it constantly holds its abdomen curved upward, tail fan raised above its head, like it's showing off.

🤝 The relationship is commensal — the shrimp gains shelter and protection without harming its host.

Cenote El Pit 🕳️✨
One of the deepest and most dramatic cenotes in the Yucatán — plunging to around 119 m! Divers descend through a stunning halocline, watch sunbeams pierce the cavern from above, and pass through an eerie cloud of hydrogen sulfide floating like fog around 30 m. Ancient tree trunks rest on the cavern floor, preserved for centuries in the mineral-rich water.

Sea Urchins 🦔🌊 Meet the spiky architects of the reef! Sea urchins (Echinoidea) come in ~940 species, with bodies covered in movable spines ranging from just 1- 2 mm to a wild 25- 30 cm long.

Some species are venomous, others are completely spineless, and a few are prized delicacies — their roe is packed with nearly 35% fat and 20% protein, making it a favorite in cuisines from the Mediterranean to Japan.

🐡Meet the thornback boxfish (Tetrosomus gibbosus) — armored in bony plates, with a raised ridge and sharp spine running along its back. Slow, clumsy, and nearly untouchable thanks to that natural shell.

Found on shallow sandy patches of lagoons and coastal reefs, foraging among algae and seagrass for small invertebrates and mollusks.

Living bells – at 30–40 m deep, giant bell-shaped formations hang, up to 2 m long and 4 m across. They're still growing today, built by extremophile bacteria that metabolize hydrogen sulfide.

A 10+ year mystery – scientists studied them from 2008 to 2018 to figure out their origin. They're less than 4,500 years old – among the youngest and strangest speleothems on Earth.

The sulfur gateway – at ~30 m, a hazy hydrogen sulfide layer appears where fresh and saltwater meet. Visibility drops to 10–15 m – it feels like diving into another dimension.

World record – only ~30 caves with similar formations exist globally, but Zapote holds the largest collection of "bells" ever discovered.

A tree from the sulfur fog – standing among the bells is a 4,000-year-old tree sticking out of the sulfur cloud. It looks like a sci-fi movie set.

👉 Now the real deal. This dive is not for beginners. Depth, deco obligations, near-zero visibility at the sulfur layer – you need a guide who knows every inch of this place blindfolded.

Dive Guru is the team that turns this challenging dive into a safe, unforgettable experience. We take only experienced divers and give you maximum bottom time without rushing. Want to see Hell's Bells at its best? Trust the ones who live and breathe this cenote.

🧠🪸 Platygyra lamellina — a Brain Coral Frozen in Stone

Winding channels with thick walls and sharply rounded ridges — a pattern that looks almost hand-carved. This shot was taken at a depth of 15 m in the Red Sea, Dahab, Egypt, macro. But this pattern has a surprising connection to the place where our dive center is based — the Yucatan, Mexico.

🌍 Range. Found on reefs throughout the Indo-Pacific, including the Red Sea, typically in shallow water on outer reef slopes.

Now for the fascinating part:

🌊 The Yucatan was once ocean floor. Millions of years ago, the entire Yucatan Peninsula — where our dive center is based today — was a shallow tropical sea. For tens of millions of years, the skeletons of corals, foraminifera, and mollusks piled up on that seafloor, gradually forming the kilometers-thick layer of limestone the modern Yucatan now sits on.

🕳️ Traces of ancient eras, hidden in caves. As sea levels dropped during the ice ages, the ancient reef was exposed to the surface — and jungle grew directly over the fossilized coral mass. Where the limestone dissolved and collapsed, cenotes and cave systems formed.

🪸 Brain corals are a common find. In the cave sections of cenotes, divers regularly come across entire fossilized brain coral colonies, millions of years old — frozen in stone, yet still showing the same unmistakable labyrinth pattern seen on a living Platygyra on the reef today.

It makes for a remarkable parallel: a living brain coral I photographed in the Red Sea today — and its distant fossilized "relatives," still waiting in the darkness of Yucatan's caves, where an ancient sea once rippled millions of years ago 🕰️🌊

💀🌊 Cenote Calavera — the Temple of Doom, Just Minutes from Tulum
Just a couple of kilometers from downtown Tulum lies one of the Riviera Maya's most recognizable cenotes. The name Calavera translates from Spanish as "skull" — and looking at it from above, it's easy to see why.

💀 Three holes, one skull. The cave's roof has three round openings: one large one (about 10 meters in diameter) and two smaller ones beside it. From above, they form the outline of a skull — the big opening as the "mouth," the two smaller ones as the "eye sockets."

🏛️ Type of cenote. Calavera is a "cántaro"-style cenote (semi-open) — its roof has partially collapsed, revealing the underground water world below, while the cave still keeps its jug-like shape.

🌊 A halocline at 12–13 meters. At this depth, freshwater meets saltwater. Because the two layers have different densities, they don't mix instantly, creating a blurry, "oil-and-water" distortion effect — like swimming through a frozen wave.

🌍 Part of Sac Actun. Calavera is a portal into the Sac Actun system, one of the largest underground rivers in the world.

🏺 Traces of the Maya. On altar-like ledges deep inside the cave, cave divers have found fragments of pottery and bones — cenotes were considered sacred portals to the underworld, Xibalba, by the ancient Maya.

☀️ The magic of light. Sunbeams streaming through the three openings create striking light pillars in the crystal-clear water — the best time for photos is early morning or midday.

🤿 For every level of training. Certified divers can explore the cenote's cavern zone — the light-filled area with a direct line of sight to the exit. Full Cave certified divers can go further, into the true cave passages of the Sac Actun system.

Calavera isn't just a photogenic spot for Instagram — it's a real gateway into one of the longest underwater cave labyrinths on the planet 🕯️

Come dive with us — at Dive Guru dive center, we run dives at Calavera for both certified divers and Full Cave divers 💙

👻🐎 The Ornate Ghost Pipefish — a ghost you could spend years searching for
Nine years of diving in the Red Sea — and only one encounter with this creature. This photo was taken on a night dive at a depth of 18 meters in the Red Sea. Meet the ornate ghost pipefish, Solenostomus paradoxus.

🔤 The Latin name roughly translates to "marvelous tube-mouth": solen means tube, stoma means mouth, and paradoxus means "strange, unexpected." A fittingly accurate description of this fish's appearance.

🐴 Not a true pipefish. Despite its resemblance to elongated seahorses — a thin body and large fins — the ghost pipefish isn't actually a "true" pipefish at all. It belongs to its own family, Solenostomidae, while real seahorses and pipefish belong to the family Syngnathidae.

📏 Size. Adults reach about 11–12 cm in length, with females noticeably larger than males.

🎭 Reef chameleons. Coloration ranges from red and yellow to black and nearly transparent — the fish essentially "matches its outfit" to a specific host: gorgonians, crinoids (feather stars), or floating seaweed. The color shift isn't instant like an octopus's — it happens gradually, over several hours.

🙃 A signature pose. It swims head-down, swaying gently with the current — the exact motion that lets it blend seamlessly into coral branches or the arms of a feather star.

🍽️ Hunting through a tube. It feeds on tiny mysid shrimp and small benthic crustaceans, sucking up prey through its specialized tube-shaped mouth — a natural pipette.

👥 Usually in pairs. Most often spotted alone or in pairs — large groups aren't typical for this species.

👻 Why "ghost." It earned the name for its ability to appear suddenly and vanish just as fast into hiding — even experienced divers sometimes only notice it thanks to a stray movement.

Encounters like this are exactly why we keep diving: nine years of searching for one shot, and it was worth every dive 🌊📸

🟠🌙 Sun Coral — the coral that only blooms at night

By day, it's just a cluster of bumpy white skeletons on a shaded reef wall or a shipwreck's hull. But once the sun goes down, these seemingly lifeless lumps burst open into dozens of bright orange flowers with translucent yellow tentacles. Meet Tubastraea coccinea, the sun coral.

🧬 A coral without sunlight. Despite its name, this species is azooxanthellate — meaning it has no symbiotic algae and doesn't photosynthesize at all. That's exactly why it can survive in dark caves, under overhangs, and at depths where most other corals couldn't last a day.

🌙 A nocturnal hunter. During the day, its tentacles stay fully retracted and each polyp looks like a closed little bump. Once darkness falls, it opens up and catches zooplankton with its long tentacles — hunting instead of photosynthesizing.

📏 Size and shape. Colonies can reach up to 30 cm, made up of many individual polyps sharing a common limestone base — but unlike reef-building corals, sun coral doesn't actually construct reefs.

🎨 Coloring. Bright orange bodies with semi-transparent yellow tentacles give it several other names too: Sun Polyp Coral, Sunflower Coral, and Orange Cup Coral.

🌍 Origin and travels. Native to the Indo-Pacific, it was accidentally introduced to the Caribbean as far back as the 1930s — likely hitching a ride on ship hulls or oil platforms. Today it's one of the ocean's most successful "migrants".

⚠️ An invasive species. In its new territories, sun coral spreads so aggressively that it outcompetes native corals and sponges, claiming substrate faster than local species can defend it.

🕳️ A deep-water record-holder. Found at depths of up to 130 meters in cold water — far deeper than most reef-building corals ever go.
Next time you're on a night dive, shine your light on a shaded wall or a wreck — you might just catch the sun coral's orange "suns" blooming right before your eyes 🔦🌊

⚓️🌊 The Wreck of Torpedo Boat S-31, Malta
At a depth of 60 meters, a ghost of war rests on an even keel — the German torpedo boat S-31.

The Story of One Night
On May 9, 1942, seven German torpedo boats set out from Augusta with orders to intercept the British ship Welshman, en route to Malta. While three boats — S-31, S-34, and S-61 — laid a minefield off Sliema Point in just 7 minutes, tragedy struck: barely a minute after the operation was completed, S-31 hit one of its own freshly laid mines.

The ship sank at 04:38. Of the crew, 13 were rescued — 13 more remained on the seabed forever.

What You Can See Today
⚙️ Three Daimler-Benz MB502 diesel engines with a combined 4,800 hp — in its prime, this boat could hit an incredible 38 knots.

🎯 The port torpedo tube — perfectly preserved, still "loaded" with a 533mm torpedo, as if waiting for the order to fire.

🔫 The automatic gun turret — still in place after 80 years underwater.

🪵 The wooden hull has rotted away, but the frame and ribs make the boat's silhouette unmistakable.

Diving the S-31 isn't just a dive — it's an encounter with a frozen moment of war on the seabed of the Mediterranean 🤿

Wrecks like this one are a reminder of why skill and preparation matter so much underwater. Deep, overhead, and historically significant sites like S-31 demand real technical training — proper gas management, decompression planning, and experience beyond recreational limits.

If you're ready to take your diving further, we invite you to join our technical diving courses, including the Trimix course, and dive these incredible sites the safe, prepared way. Join us on one of our dive trips around the world.
