Ocean Superhero - Ep.3

In the previous two episodes, we discussed ways in which we can reduce our plastic footprint and in so doing, become Ocean Superheroes and save some Marine lives.

Today, in the final episode of this trilogy, we take a closer look into our cupboards and see how a change in our personal products can turn us into Ocean Superheroes.

1. Glass is class:

Whenever possible, choose personal care products which are sold in glass containers, instead of plastic. Glass is better for the ocean and has no toxic seepage sneaking into your product, which inevitably builds up in your body.

2. Beware of your butt.

Cigarette filters are not biodegradable, so please do not just flick them out your car window! They are made of plastic fibres and are filled with chemicals and carcinogens. This deadly combination seeps its toxic concoction into the environment, causing a wake of death. Smokers, please be responsible with your butts and ensure that you place them in a bin, where they can be disposed of properly and not end up in the ocean.

3. Ban the Bead!

Plastic microbeads are everywhere! Grocery aisles are beset on all sides by these micro-tyrants. What are they? Tiny, little balls of plastic.

They are usually colourful to catch the consumer’s eye and you will find them in your toothpaste, your facial or body scrub, in your wrinkle fillers, in your laundry powder, your cleaning detergent or in your shower gel. These microbeads are ineffective as exfoliators (whether on your skin or on dirt) as they are so smooth and round that they offer zero exfoliation. Instead, they wash down your drain, pass through the water filtering plants and rinse out into our waterways, ending up as lunch for some unsuspecting fish, crab or oyster. In just 1 shower, you can release 100 000 of these microbeads. So, ban anything which states “Now with micro-particles” or has any of the “poly’s” in its ingredient list. They may look pretty, but they are useless and deadly!

4. Go natural!

If and when possible, choose natural products over synthetic/chemical based products. From personal care products to cleaning products – eventually, they all end up in our drains and further downstream in our waterways. Vinegar and Bicarbonate of Soda can replace several bottles of chemical cleaners in your kitchen cupboard – cleaning more effectively, costing less than ordinary scrubbers and being far kinder to the environment. You will also be surprised to learn how many little tubes and bottles in your bathroom cabinet can be replaced with lemon juice, bicarbonate of soda or coconut oil! Don’t believe me? Go on, Google it!

The most important message I wanted this trilogy to get across to you, is this:

If it is better for the environment, it is better for you too. How much is your health worth to you? How much is the health of your environment worth to you? Make the switch, it won’t cost you more, it simply takes a shift in thinking and changing gears in the daily choices you make. Fight the scourge which is ocean pollution and become the ultimate (and healthy) Ocean Superhero!

Ocean Superhero - Ep.2

In our previous episode, you were introduced to 5 simple steps/choices to reduce your single-use plastics, as well as the repercussions of said plastics. In this episode, I will be showing you how your food choices can help save some lives – no, don’t worry, I am not jumping on the vegan band-wagon! Read below for more tips on how to become an Ocean Superhero!

1. Breaking Bread:

If you are like me, then there’s nothing more comforting and satisfying than fresh bread. And herein lies the superhero secret – purchase freshly baked breads from a baker, wrapped in paper, instead of those fake, mass-produced, plastic-wrapped breads we buy in the name of convenience. Not only are fresh breads nutritionally better, purchasing them also supports the “little guy” instead of huge corporations. And of course, there’s no plastic thrown out with the crumbs.

2. Put the freeze on frozen foods:

Firstly, frozen foods have lost almost all of their nutritional values by the time you have defrosted and reheated them. Secondly, they are all packaged in plastic. (aargh! The horror that some foods are actually microwaved in their plastic, which releases the plastic toxins into your food!)

Save your health and those of marine animals and opt for fresh vegetables instead of frozen ones. Take time and pre-cook your meals for the week ahead, freeze them in reusable containers and simply reheat and eat when you’re hungry.

3. Farm Fresh:

Speaking of fresh produce, a fun and effective way to rid yourself of all the excess plastic packaging our foods are wrapped in, is to shop at your local Farmer’s Market. Take your basket and fill it with plastic-free, fresh and (usually) organically grown foods. Your body and the oceans will thank you.

4. Gum is not gum!

Sure, we all like to have fresh breath, but did you know that your chewing gum is not made from natural gum? Nope, you are chewing on a piece of mint flavoured PLASTIC!

Gone are the days when actual gum from trees were flavoured for your chewing pleasure. Now, “gum base” is the umbrella name for anything from resin to elastomers, (the molecular composition of which is very similar to plastic). Your gum may also contain polyvinyl acetate, which is infamous for causing tumours. So basically, we are chewing sugar-coated, tumour-forming plastic… yummy. But remember, all these billions of pieces of chewed plastic, eventually gets spat out and it has to go somewhere…

5. I scream for Ice-Cream!

Go ahead, treat yourself, have an ice-cream! But out of respect for our oceans and the environment, please make it an ice-cream cone, and not one of those over packaged, brightly wrapped ice-creams from the supermarket. And try to avoid the big plastic tubs of ice-cream too – both your waistline and the oceans will be happy!

Ultimately, these 5 choices will improve your health and save the lives of marine animals like whales, turtles, dolphins and an ark-full of other species – in fact, over 100 000 marine animals and 1 million sea birds die each year due to plastic.

Ocean Superhero - Ep.1

Our oceans and marine life are being choked by a continuous supply of plastic; from plastic bags and bottles, to straws and microbeads. 80% of marine plastics come from land-based sources, which are then blown or washed into the ocean. Plastic travels well and ends up on shorelines, in the stomachs of ocean life, and as giant floating islands, thousands of miles from civilization.

Annually, more than 8.8 million tonnes of plastic end up in our oceans. That’s the same as five grocery bags filled with plastic, for every foot of coastline in the world!!! That is seriously disturbing and it all seems so overwhelming that you might be thinking to yourself: “Well what can I do about it and would it actually help at all!?”

In 2008, the average amount of waste generated by each person in America per day, was 4.5 pounds (2.04kg).Imagine we all reduced our waste by 50% and we multiplied that by 7.5 billion (people) - surely that would have a beneficial impact?

Read these 5 simple ways to start reducing your single-use plastics and you will see how easy it is to become Ocean Superheroes (no super powers or genetic mutations needed)!

1. Drink Responsibly

Americans use an estimated 50 billion plastic water bottles a year, of which only 23 percent are recycled. So, ditch the dodo, buy water in glass bottles or invest in a reusable container and save some lives in the process.

2. Get your fix, the eco-way!

Your daily caffeine fix is more than likely aiding and abetting the plastic scourge. Every cup of Java comes hand in hand with a plastic lid, a plastic stirrer or in fact, the very cup might be plastic! The average American office worker uses about 500 disposable cups every year.

If you break your plastic addiction by buying a travel-mug, not only will you prevent hundreds of pieces of plastic from entering the environment, but you will also protect your own health!!! When in contact with heat, plastic/Styrofoam releases a whole chemical cocktail, which seeps into your daily fix and absorbs into your body.

3. Refuse plastic straws:

500 Million straws are used in the USA, EVERY DAY!!! That’s staggering! Straws are an unnecessary evil - refuse a straw the next time you buy a soda or milkshake, or get some funky glass straws (they are quite durable!). Need motivation to make this change? Watch this: https://youtu.be/d2J2qdOrW44

4. Ban the Bag:

Every year, Americans use approximately 1 billion shopping bags, and worldwide we use a total of 500 billion plastic bags. By making a simple choice you can save lives – lots of lives: One survey of leatherback turtles found that 1 in 3 has at least one plastic bag in its stomach, where it causes pain and leads to starvation. Please switch to reusable shopping bags, the following video might assist the process: https://youtu.be/oxLWt8NDneI

5. Fork the Knives:

Instead of accepting plastic cutlery with your take-out, rather invest in some eating utensils which won’t end up in the bin once the meal’s over. Sticking with metal or bamboo eating utensils which you can reuse, would help the ocean and its creatures breathe better. This video clip might help bring this message home to you: https://youtu.be/VRiTABRQOjk.  Daily, we are accosted by myriads of plastic in different ways, and there are a multitude of simple (and cost-effective) ways in which we can minimize our plastic footprint.

So, start making choices today that will turn you into an ocean superhero, saving lives with the choices you make – It’s like another superhero once said: “It’s in your hands to create a better world for all who live in it…” Nelson Mandela.

White Shark Sightings

Winter in the Southern Hemisphere is known as the best season to view Great White Sharks. Here in Gansbaai, we have sharks all-year-round, but Winter is still traditionally considered as the best season. There are a few contributing factors, such as the fact that there are more sharks hanging around Shark Alley during Winter, the water visibility improves and the water temperature is a few degrees warmer than in Summer. Thanks to the Great White Shark’s rete mirabile, they are able to raise their body temperature about 10’C warmer than that of the surrounding water, which in layman’s terms relates to the sharks being a little lazy when the water is cold and when the water is warmer, they feel a little friskier. The big males make their appearance in winter, just in time for the Cape Fur Seal pups to take their first plunge into the Atlantic and test their aquatic skills. Generally, we see more females than males during Summer and more adult males during Winter.

If you look at our data from 2015 however, you will notice a pattern that does not support what I’ve just told you. Now, I understand that when it comes to the collection of Biological data, it is not as clean and neat as pure statisticians would like it to be; the variables are all over the place! I am all for statistics, it is fascinating, it gives us insight and better understanding, but sometimes it also gives us more questions than answers. And 2015’s data is very intriguing indeed...

The Western Cape of South Africa did not get its nickname “The Cape of Storms” for no reason; Winter in the Western Cape is infamous for its gale force winds and feisty cold fronts, which whips the Atlantic Ocean up into a frenzy and of course, has a direct impact on the amount of days we can go out to sea. Therefore, one could deduce a direct correlation between the amount of trips done per month and the number of sharks spotted. Which is probably why we saw nearly 330 Great Whites in February and only a 140 in May. We did not have good weather in January, so we had quite a few “no sea days”, but January is not known as a good shark-month, so one could expect a low number of sightings. September is still considered good shark-viewing season, but the weather did not permit many trips out to sea, which then gives us the self-explanatory low figure of 84 Great White Shark sightings.


But this is where it gets intriguing: why did we see so many males in February, if traditionally we see more females than males in Summer? And why do we generally see more adult females than adult males? The males we do see tend to be juveniles, which brings me to another question: why do we see so many juvenile sharks in our area? Could one be blamed, if one came to the conclusion that there may well be a Great White Shark nursery in our waters? I mean think about it: Lots of adult females, not so many adult males, and loads of little juveniles of about 1.2m in length, which is practically newborn size. Hmmm, it does make you wonder, doesn’t it?

Now if you consider the strange phenomena we experienced during January and February of 2016, where we had no shark sightings for 5 weeks; could these hiccups in our 2015 pattern have been the warning signs of the impending crisis, much like cumulus clouds are the forerunners of a storm? Were these hiccups caused by the El Nino and can we indeed blame the El Nino for making our sharks disappear for those weeks? Guess we will have to wait until all the data has been accumulated and assessed – will keep you posted!

Shark Vision Facts

1. Effective up to 25 meters

2. 10 times greater than humans in clear water

3. Eyes very similar to humans – cornea , lens, retina, iris, pupil

4. Contains rods and cones so can detect colour and see in low light – new research (2011) shows not all sharks have the same cones cells, bull sharks cannot see in colour.

5. Tapetum lucidum – detects very small amounts of light which is why they can see in very murky water

6. Can see out of the water as well – pupil dilation

7. Iris is a vivid blue colour

8. Nictitating membrane (eye lid) lacking in great whites so they roll their eye back for protection

And in other shark related news;

Donald Gibson found the first vertebra just as he had begun to dig out the space for the sunroom he had promised to build in the back yard of his parents' home in Calvert County, Maryland, USA.Over the following week more and more vertebrae were found — each one about 18 inches deep into the groundBut then they found a straight column of vertebrae, two feet long as well as a tooth.

The digging stopped.

What the Gibsons unearthed were the remains of a 15-million-year-old Snaggletooth shark found, which palaeontologists say is more complete than any other fossil of its kind in the world.

The Gibsons' discovery is so unusual because of the number of bones they found — more than 80 vertebrae and hundreds of teeth, all from the same shark — as well as the position they were in and their unusually good preservation.

Palaeontologists Godfrey and Nance were called to the scene and they were amazed at the find. They immediately wrapped the entire skull cavity in a stiff plaster cast, like one used to set a broken bone.

Sharks' skulls are made mostly of cartilage, not bone, so they almost never withstand the ravages of time. Yet somehow, the shark that came to rest in the Gibsons' backyard sank belly-up when it died during the Miocene Epoch. It became buried in sand, then by sediment eroding from the Appalachian Mountains. And its skull cavity — containing hundreds of the distinctively shaped teeth, up to an inch-and-a-half long, that give the snaggletooth its name — kept its shape.

Using a microscope, the scientists digging in the Gibsons' yard were able to see the distinctive hexagonal shape of shark cartilage, fossilized and preserved.

Godfrey said that this shark was 8 to 10 feet long during its life.

Having preserved the teeth and surrounding remnants of cartilage in exactly the positions they were found in, the palaeontologists will be able to take CT scans of the cast and analyze the specific three-dimensional layout of the prehistoric shark's mouth, something scientists have never done.

"For the first time, we're going to be able to know what the dentition — what the teeth — looked like in this kind of shark," Godfrey said.Then they will remove the cast, gently clean each piece and put the discovery on exhibit.

Godfrey said he is receiving emails from palaeontologists up and down the East Coast who are excited about the discovery.The skeleton will allow scientists to compare the prehistoric snaggletooth, an extinct species, and modern snaggletooths, a descendant species that lives in the Pacific.

Comparing the teeth of snaggletooths then and now will help scientists understand the workings of shark evolution, the likely diet of prehistoric species and the climate during the Miocene Epoch.

And the fact that the spine and the skull cavity of the shark found by the Gibsons are definitively associated with each other, the most complete snaggletooth skeleton ever found will allow scientists to identify whether smaller pieces of future fossils come from snaggletooths or other species.

"When in the future we find just a single vertebra, we'll be able to say, 'This comes from that kind of shark.' And only because we have this association being made," Godfrey said. "It's just incredibly unlikely that we would make this kind of discovery."
