Getting ready for summer
– Scubatainment style!
“We pledge to bring you the weird, the wholly
unusual and nothing but the bizarre.”
It seems a bit strange to be introducing Scubatainment’s
first spring edition whilst most of us are still in shock over the
fluffy white blanket that covered the country recently – many
repeating, for the hundredth time, that it hasn’t snowed in
Pretoria for 20 years, or secretly wondering whether the bizarre
weather is a sign of our impending global warming doom (or
Sabrina Hindley
Publisher/
Editorial Director
even more secretly if this means that the world really will end in
December). However, as we watch winter make its exit to torture
the inhabitants of the north for a while, we can’t help but get
excited about summer and the warm waters, sundowners and
diving trips that follow in its wake – and keeping in line with
that excitement, we’d like to present the September issue!
We’re absolutely thrilled with the number of Scubatainment downloads so far (and
climbing)! If there’s still anyone out there unaware of the best thing to happen to
diving since decompression chambers, I would like to point an admonishing finger and
say that you clearly don’t know what’s what!
What a welcome sight as the dull weather and cold temperatures trade places with
sunshine and warmth! Much like spring is characterised by ideas of renewal and
regrowth, Scubatainment, too, bursts forth with fresh ideas! And so yet another
glorious edition blossoms; sure to put a spring in your step!

There’s something about the ocean – the sound of the waves, the sense of endlessness
and the adventures it promises just behind the horizon that really speak to the soul.
But after finding out about the odd things that lurk beneath its surface, I’m not sure
I’m ever going near it again.
A fish in Florida called the gurnard makes grunting noises before a thunderstorm and
is 100% accurate. The lung fish can live out of water for as long as four years, and fish
that live more than 800m below the ocean surface don’t have eyes. This goes to show,
the deeper you go the weirder the fish… just like Scubatainment! The deeper you

THE WHITE ORCA
Far East Russia Orca Project (FEROP)
scientists recently spotted a white orca off
the Commander Islands in the North Pacific.
While there have previously been two
sightings of the white orca, researchers are
unable to say if it is the same one, possibly
making it the only one of its kind in the
world, or even if it is an albino or not.

FIRST WILD FISH WITH SKIN CANCER
After examining coral trout in the Great Barrier Reef, a team of researchers found
skin cancer lesions on the fish resembling human melanoma. It is believed that
this is the result of the fish being radiated through the hole in the ozone layer
underneath which they live.
OCEAN RUBBISH ON THE
INCREASE
Northern fulmars on the north-western coast
of North America delivered some shocking
findings after their stomach contents were
inspected. More than 90% of the birds had
ingested pieces of plastic. Northern fulmars
are a good indication of what’s going on in the
oceans because they feed exclusively at sea
and the plastic remains in their stomachs for a
long time.
A GREAT WHITE SMILE
Ever wonder why sharks have such perfect
teeth? A recent examination found that they
contain fluoride – the same stuff you get
in your toothpaste. While very convenient,
it does also help that their teeth are
constantly replaced by new ones.

POLAR BEARS: GLOBAL
WARMING-PROOF?
Recent studies comparing living polar bear DNA
with a 110 000-year-old polar bear jawbone
and brown and black bear genomes found that
polar bears are much, much older than previously
thought – diverging from the brown bear line four
to five million years ago. This would also mean that
they have previously survived global warming. Will
they survive the human-induced global warming of
today? That remains to be seen.

6 | DEEP MELODIES
The Sounds
of the Deep
I’m all outta love, I’m so
lost without you...
Feel like spoiling that special someone
with a “deep” and meaningful song that is
bound to make him or her fall in love with
you all over again...? Well then, maybe you
shouldn’t read this.
E
ver since the dawn of time, whales
have used singing as a method
of communication, enchanting
each other with sweet melodies from
thousands of kilometres away. While the
graceful sounds of the deep have the
ability to calm the wild sea beast, and
bubble into underwater romance, I’m
sure many would agree that although
the instinctive gesture to sing beautiful
harmonies is appreciated, some should
be left in the aquatics (thousands of
kilometres away).
Yet one stops to wonder if the use of
such sounds is a subconscious urge to
mimic the great swimming Casanovas.
We suggest you to take a listen to these
“tranquil” tunes and decide for yourself
if the heartfelt lyrics are beautiful
renditions of sea-like sonnets, or the
clumsy murmurs of a truly hopeless notso-romantic giant squid.

Love me, love me, say
that you love me...
I wanna be loved by you,

And that’s why birds

eminiscent of a scene on Bikini
Bottom where sea sponge,
SpongeBob, and his underwater
friends gather at the Krusty Krab for
a hearty meal, the Ithaa Undersea
Restaurant offers people a similar
experience – the opportunity to dine
with a spectacular panoramic view of the
underwater world!
This innovative restaurant, located at
the Hilton Maldives Resort & Spa, is the
first of its kind in the world. Ithaa
consists of three 5m wide x 125mm
thick glass arches that sit 1m below the
sea level during low tide, and almost 2m
at high tide. This clear glass arch offers
a panoramic view of the Indian Ocean,
with all its beautiful sea creatures. At
the time of construction, this was the
widest constructed underwater structure
in the world. The inside of the restaurant
is 9m long and 5m wide and sits above
the seabed.

Kanye West
Love Lockdown
This song truly takes an original approach
to trying to sing underwater. Kanye is
certainly enjoying the bubbling vibrations,
and the bucket of water. But when you
realise it is in fact a romantic love song,
it makes you wonder. Like the sailors’
tales of luring mermaids, is Kanye too,
deceivingly luring you to the dark depths
below, never to be seen again?

Right from the get-go the title explains
it all. With a deep humpback whalelike voice, the main singer enchants his
way into an almost trance-inducing sea
mammal murmuring chorus.

My Bloody Valentine
Loveless
A rather fitting title for the feel of this
trippy track. This song sounds like a
deep sea kraken arising from the depths,
rejected and angry, and vengefully
devouring you Little Shop of Horrorsstyle.

Boredom
The Mollusc
Let’s be honest here, who in their right
mind makes a song about finding a
mollusc on the beach, with its one eye
looking at the sun? Creepy. This is the
most random sea-inspired song on our
list, by far.

If slow-moving emo sea turtles ended
a 100-year relationship and thereafter
stalked each other from the shadows, this
would be the theme song.

Loscil
Submers
This song does not change for the entire
seven minutes. If you can stay awake
through the droning amniotic melody, you
start hearing what sounds like tiny shrimp
following you on your meaningless
binaural journey. Definitely not one for
Valentine’s Day.
So there you have it, your ultimate
oceanic compilation! A romantic holiday
at the coast would surely be incomplete
without these salty… um we mean sultry
sea songs!

In addition to the leafy sea dragon, you
can also find the weedy sea dragon there,

in the wild is quite the rare experience,
especially considering their talents in
keeping hidden.
All in all, the leafy sea dragon is quite
the majestic little thing, which in
combination with its foliage lent it its
name. Unfortunately, leafies are listed as
near threatened by IUCN due to habitat
loss and long-fingered aquarists who are
also incapable of keeping them alive in
captivity. Australia takes its sea dragons
very seriously, however, and care is taken
with protection for both species.

its head – making seaweed and kelp

the AquaDom, and it’s a 25m-tall
cylindrical acrylic glass aquarium
with a built-in transparent elevator,
located at the Radisson Blu Hotel in

The AquaDom is the world’s largest
cylindrical aquarium and contains
one-million litres of seawater where
a multitude of exotic and tropical fish

Berlin where the highlight of the Sea Life
tour is a ride in this unique elevator. The
combination of the Aquadom with the
Sea Life Centre makes this one of Berlin’s
most popular attractions.
So, in this story, much like the
Roald Dahl version, visitors begin their
adventure by exploring the aquarium
and its interesting inhabitants – from
the curious and the rescued, to the
rare and the enigmatic. There are over
5 000 creatures located in more than
35 water tanks of various shapes and
sizes. There’s even a fun mirror maze!
These mirrors reflect a multitude of
images of underwater life, giving a very
unreal atmosphere through incredible

22cm at the bottom.
The cylinder has a diameter of 11.50m.
The water level is 14m.
One million litres of water is enhanced
with 33 tonnes of sea salt (salt content
of 3.3%) and is circulated every hour.

THE DEEPER YOU GO, THE WEIRDER THE FISH
As is often said by people we assume are knowledgeable on the subject, we know
more about outer space than we do about our own oceans. Regardless, how little
we know is proved time and again when some anchor or submarine surfaces from
somewhere very far down and returns with some of the oddest fish you’ve ever
seen. The latest rare finds east of New Zealand from a team looking for life below
2 000m, included a flabby whalefish, slickheads, rattails and a cusk-eel.

MISSING: 10 000-YEAR-OLD BONES
Earlier this year, a skeleton was stolen from a cenote in the Yucatán
Peninsula. The remains, called Young Man of Chan Hol II, are
believed to be more than 10 000 years old, and from one of the
first inhabitants of the Americas. Scientists were reportedly very
upset upon discovering the theft, and put up missing signs in the
nearest town. The question of just why anyone would steal human
remains has not as yet been raised.

SAFE AT ANY DEPTH
CMAS Courses range from Entry Level

from Dive Master to Instructor Trainer.
Be part of the world’s biggest diving
organisation, CMAS – represented in

Looks like SA’s remedy for
success at the Olympics
is “Just add water”. Maybe
we’d have won more gold
