Jewels in the Muck



Muck diving in Bali

There is nothing as satisfying as a cup of hot strong sweet black Balinese coffee, served in a glass on the beach after your first muck dive. And there is nothing as astonishing as the critters you find in the old car tyres, empty beer bottles, lost bikini tops and empty foil packets covered in ancient volcanic ash silt.

Adi Assri Resort

This is Muck Diving in Bali. As a spoiled South African Sodwana Bay diver and a confirmed addict of well-balanced reefs, pristine corals and beautiful shoals, I had never realised that there could be a secret thriving world of resourceful marine life in the desert wastes of the undersea world, where tides regularly sweep away their habitat and man provides most of their hiding places.

It was a 10 hour flight on Air Malaysia to Kuala Lumpur, then a short 2.5 hour transfer to Bali, which is 6 hours ahead of South Africa. We paid extra for the VIP Meet and Greet and Border Visa service offered by our Dive Operator and we were whisked through the airport immigration as “crew” and through customs in 5 minutes. The Dive Operator’s air-conditioned mini bus carried us through the ancient Spice Island plantations of cinnamon, nutmeg and cloves, and we arrived at the Adi Assri resort in Gilimanauk, home for our first week. We spent the next day getting used to the new time zone and discovering that fruit and fresh vegetables are very big in Bali, Bintang Beer excellent, and Balinese food is best – Hindu’s are not big on beef, so avoid steaks at all costs. Magnum ice-cream is everywhere. Cash is best from ATMs, not money changers who cheat; plastic accepted in urban areas.

Secret Bay

Parman and Wayan

Secret Bay on the North-western tip of Bali is mind-blowingly ugly. Surrounded by mud flats and mangroves with dirty black sand covered in silt deposits, this world famous dive site looked truly awful. It is tidal, so you have to dive it when the tide is rising, or it’s too murky to see.  You have to completely change your perception of marine life. It is not all as delicate and fragile as we think. Some of it is tenacious, vigorous and adaptable, and the rarest life forms are found in the most inhospitable places.

We had elected to pay extra for a private dive guide and Parman the dive guide and Wayan the driver were to be our mentors for our entire 25 day stay in Bali.

At the shore entry point there was everything a diver needs – change rooms, showers, cleanish Balinese loos with no paper but a sort of bum-shower arrangement that was a bit disconcerting until one got the hang of it, fresh water troughs where our mentors rinsed the gear, and an ethnic cafe bar where we had lunch, part of the dive package. We kitted up on shore, and sank gently in 28 degree crystal clear water and silt coated rubbish. Finning cautiously to avoid stirring up the silt we drifted down to a maximum depth of 8 metres, scouring the silt for critters.

Bangai Damsels

In a pile of discarded burglar guards, we found the first of the muck jewels – a school of Banggai Damsels. Long- spined sea urchins hosted the juveniles, who later graduate to bigger hideouts.

Then Parman found a Mimic Octopus. This was incredible luck, as he is still un-described. He defends himself from predators by mimicking poisonous or unpalatable creatures. He was outraged at being spotted, and quickly reformatted himself into a poisonous brittlestar, hoping he would fool us.

Mimic Octopus

We saw drifts of shrimpfish, bobbing mouth-down as they hoovered up minute particles of food; we saw common and rare seahorse, a plumed shrimp and coral crabs, a juvenile Oriental Sweetlips,  schools of batfish, fusiliers and cardinals, both familiar and rare. There were poisonous banded sea-snakes, coiled in hollows, covered in silt and disguised as sea cucumber turds. Our last find was the highly sought after Mandarin fish (Synchiropus Splendidus). He was hiding in a pile of discarded nets, and exquisitely colourful.

Critters are nervous. They can never be sure whether their homes will still be there when they return from feeding, as the plastic bags move with the currents and the tides. It needs a trained eye to spot them and Parman had an amazing knack for finding rare things. We spent 180 minutes underwater over our 2 dives, used up all our air and took 380 photographs. It was one of the most outstanding sites I have ever dived.

Plumed Shrimp (Leander Piumosus). Rare and gorgeous.

That evening we discovered Bali’s second best secret. There are skilled masseurs all over the island, most hotels and resorts have spas and they all offer Balinese massage. You haven’t lived till you’ve tried one. It costs around R150, lasts an hour or so and creates the most blissfully languid feeling after a hard day’s work lying in warm water looking at beautiful things.

Puri Jati

Spanner Crabs and Snake Eels


Our next major dive site was Tulamben where we were to spend another week. On the way we stopped for two dives at Puri Jati, a small Northern coastal farming community, where families cultivate the rice using hysterical little two-wheeled tractors. Wherever we went there were little palm baskets of flowers and rice in miniature temples and on pathways. We enjoyed the flowers, the birds ate the rice. This culture of sharing one’s bounty with others pervades Balinese culture, and makes for a wonderful feeling of harmony on the island. The only Hindu Island in Islamic Indonesia, Bali is volcanic, suffers occasional earthquakes and their Hindu religion pacifies their gods and keeps the volcano quiet. Rice paddy terraces are everywhere, and temples and exotic flower gardens in even the humblest homes.

In Bali, a diver’s most basic needs are met at every dive site. Our gear was carried down to the beach and again, we kitted on the shore. In Bali the men take care of the gear while the women are the porters. We sank into crystal clear water, on strangely round-grained fine sand with very little silt. But this was desert. No rubbish or rubble, nothing but sand.

Napoleon Snake Eel (Ophrychthys Bonaparti)

We wandered after Parman, wondering why we were wasting time on this barren place, when his critter hooter sounded and we finned up to him. It was a Pegasus Sea Moth. Rarely spotted, this solitary sand dweller was walking purposefully across the sand on his “feet” – his fused pectoral fins. And right beside it was the most exquisite little creature, swallowing and gasping and finning round in circles – a very juvenile pufferfish, the size of a thumb nail.

As the sandy bottom began to slope we found a mooring rope attached to a pair of old car tyres. Inside was this exquisite, juvenile lion fish right beside the elusive and quite beautiful Ornate Ghost Pipefish. The colours of the stripes were the same on both, and they looked almost as though they had been colour-matched by an interior designer.

The slop began to come alive as we got used to a whole new way of looking at the undersea world. Suddenly we began to notice the minute partner shrimps in the anemones, the strange yellow and brown blobs in the sand that were three types of snake eels. All you could see of them was their snouts and their unblinking eyes, and rare and unusual creatures began to come into focus. There were half a dozen species of lizard fish. There was a drab brown silt covered sea horse that shied away as we approached. There was a minute squat lobster clinging to a sea pen, and a minute red juvenile frogfish.

Commensual Sea Pen Shrimp (not identified)

One creature needed no such focus though. He was 15cm across, planted four-square in the sand, hunkered down and immovable, and he made Parman’s day. We were still too unfamiliar with the Bali fauna to know how privileged we were to see him. He normally lies completely buried in sand, and our bible, Ferraris’ book Macrolife has a picture of him. It shows only his eyes and his antennae. He was a Spanner Crab (Ranina ranina), hard to spot, rarely seen, and posing for pictures. Parman’s smile lit up the micro-bus all the way to Tulamben.

Seraya Slope, Tulamben

Soft Silt and Giant Mantis Shrimps

The ash based silt coating the volcanic slope at Seraya, Tulamben was so fine that it was almost impossible to fin anywhere without clouding the water. As we inched cautiously across the rocky slope we noticed some large holes each about 12 centimeters across and beautifully lined with fine vegetable matter. Clearly the architect was a master of materials control, since they remained stable even in the friable silt. We had no idea what could have made them.

Boxer Crab (Lybia tesselata)

Our first critter was the Boxer Crab (Lybia tesselata). Difficult to find, shy and retiring, he arms the tips of his chelipeds with anemones whose sting protects him from predators. This rare and beautiful crab was out in the open, with his defences raised and a belligerent look on his face. He clearly had no idea how big we were, and was quite willing to fight us off if necessary. There were clumps of stunningly beautiful chrinoids, in every conceivable colour, and amongst them Parman found the Chrinoid squat lobster (Alogalathea elegans). It was not until we identified these two in Macrolife that we realised how rare these sightings were.

Chrinoid squat lobster (Alogalathea elegans)

As we reached the end of the dive Parman again found one of the mysterious lined holes, and began to scratch around the edges. We peered into the hole, and watched in astonishment as the most amazing creature began to emerge. The size of a rugby ball, it had 2 double eyes, and it looked like a Star Wars android. It was the Giant Mantis Shrimp, (Lysiosquillina lisa) the legendary creature capable of shattering the camera’s Ikelite lens housing. However, it was feeling benevolent, and posed for several photographs before growing bored and ducking back into its hole.

The Balinese people are essentially joyful, good humoured and happy. Thank you we say, you’re welcome, they reply with a smile, and they really mean it. When your world could vanish overnight with an exploding mountain on your doorstep, and an angry sea might threaten a tsunami, you have to be pretty philosophical. And if tourism is your source of revenue in a competitive world, you also have to be pretty cheap.

Peli proud to support COVID-19 vaccine distribution



We know Peli from its popular camera cases, but from discovery to distribution, Peli’s temperature-controlled packaging is now delivering COVID-19 vaccines all over Europe and the Middle East

With the pandemic recovery just underway, COVID-19 vaccines and therapies are rapidly becoming available for use and they must be safely distributed worldwide, within their required temperature range. Peli’s BioThermal™ division is providing temperature-controlled packaging to meet this critical moment, protecting these crucial payloads.

Peli’s innovative cold chain packaging has been trusted for nearly 20 years by pharmaceutical manufacturers to safely ship their life-saving products around the world. To meet the current challenge, they have adapted their existing products to provide deep frozen temperatures when required for the newly developed life sciences materials. Current and new offerings will ensure the cold chain is maintained throughout the vaccine or therapy’s journey, maximising efficacy and patient health.

“We know that pharmaceutical companies are in all phases of the development process for vaccines and therapeutics and working tirelessly to bring safe and effective drug products to market quickly,” said Greg Wheatley, Vice President of Worldwide New Product Development and Engineering at Peli BioThermal. “Our engineering team matched this urgency to ensure they have the correct temperature-controlled packaging to meet them where they’re at in drug development for the pandemic recovery, from discovery to distribution.”

Peli BioThermal’s deep frozen products use phase change material (PCM) and dry ice systems to provide frozen payload protection with durations from 72 hours to 144+ hours. Payload capacities range from 1 to 96 litres for parcel shippers and 140 to 1,686 litres for pallet shippers.

New deep-frozen solutions are ideal for short-term vaccine storage, redirect courier transport of vaccines from freezer farm hubs to immunisation locations and daily vaccine replenishment to remote and rural areas.

Peli BioThermal temperature-controlled packaging is currently being used to distribute COVID-19 vaccines and therapeutics, either directly or through global transportation providers, in Denmark, France, Italy, Germany, Spain, Sweden, and the UK as well as in Kuwait and Saudi Arabia in the Middle East, with more countries set to join the list as the pandemic recovery process rolls out.
