A Summer of Tragedy: Why Ocean Education Matters More Than Ever

Why Sharks Matter

 

A Summer of Tragedy: Why Ocean Education Matters More Than Ever

The recent series of shark encounters in Sydney, including one tragic fatality, is a sobering reminder of why education about the ocean and its inhabitants is so important. While these events are devastating, they also highlight a crucial truth: understanding marine environments, shark behaviour, and safe swimming practices can significantly reduce the risk of dangerous encounters.

If more people had a basic understanding of shark movement patterns, feeding behaviour, and how weather events affect ocean conditions, many of these incidents may have been avoided.

Shark & SurferHow Heavy Rain Changes Shark Behaviour

Over summer, Sydney experienced substantial rainfall. This causes large volumes of freshwater, along with pollution and runoff, to flow into rivers, canals, and bays. Bull sharks, which often inhabit these areas, are forced out of their usual environments in search of cleaner, saltier water.

As a result, they move along the coastline and closer to popular recreational areas such as Sydney’s Northern Beaches.

However, even coastal water after heavy rain is often murky and dirty. In low-visibility conditions, sharks cannot rely on sight to hunt. Instead, they detect vibrations in the water. Erratic splashing or surface movement can feel like injured fish or prey, causing sharks to investigate. They do this with their mouths, which can result in catastrophic injuries to humans.

It’s important to understand that sharks – including bull sharks – do not consider humans to be food. These encounters are cases of mistaken identity.

Safer Swimming Starts With Knowledge – The Message is Simple & Clear:

Swimmer at Dusk

Avoid swimming in murky or dirty water, especially after heavy rain

Don’t swim at dawn or dusk, when visibility is low and sharks are more actively feeding

Pay attention to water conditions, warnings, and local advice

If more people were armed with this knowledge, safer swimming practices would be far more widely followed – and the risk of incidents would be greatly reduced.

Education, Not Fear, Is the Answer

We must learn to live with the environment and all that is in it, not try to change it to suit ourselves. Culling sharks is not the answer to making the ocean safer.

Education is.

By teaching children and adults how ocean ecosystems work, how animals behave, and how to safely enjoy our beaches, we empower people to make smarter, safer choices – and protect both humans and marine life.

At Ocean Life Education, this is exactly what we believe in: building understanding, respect, and knowledge so we can all enjoy the ocean more safely and responsibly.

Sharks Down Under – Amazing Australian Shark Facts

Hammerhead

Contrary to popular belief, mainly brought about by scary shark movies, you have more chance of being killed by a coconut than a shark! Over-fishing and unsustainable practices are causing shark populations to decline worldwide. Amazing sharks play an important role in our oceans and on our majestic reefs and we should all be concerned about their numbers declining. We believe that the big danger is not sharks; the big danger is shark extinction. Here in Australia, we are luck to have bountiful species of shark living off our coastline. Read on to discover some interesting facts about sharks of Australia, why we need sharks in Australia and why we need to protect sharks living off the coast of Australia in our Amazing Australian Shark Facts blog…

 

Sharks in Australian Waters

Shark resources

There are considered to be around 180 species of sharks in Australian waters and 500 species worldwide. In fact, around 50 species of shark live right here, off the Eastern Coast of Queensland. Eastern Australia’s grey nurse sharks are considered critically endangered and school sharks (sometimes known as flake in fish and chip shops) and scalloped hammerheads are on the endangered shark list too.

 

Sharks Commonly Found off Australia

The following sharks are commonly found off Australia’s coast: Great White, Port Jackson, Thresher, Zebra Shark, Tiger Shark, Tasselled Wobbegong, Whale Shark, Oceanic Whitetip, Blacktip Reef, Grey Nurse, Bull Shark, Bronze Whaler, Great Hammerhead, Blind Shark, Pygmy Shark

 

Why Do We Need Sharks?

 There is no doubt that we need sharks. As apex predators, sharks help maintain the balance of life in the sea. Sharks are a vital part of the food chain, controlling mid-sized predators and allowing small reef fish to thrive. Small reef fish take care of our amazing coral reef, therefore sharks help keep coral reef healthy. Without sharks, we would be denied the pleasure of exploring amazing underwater habitats such as the world’s largest natural wonder, Queensland’s Great Barrier Reef. The global economic impact on tourism and of declining fish stocks would be huge. So, have no doubt, we need sharks!

 

Why Are Shark Populations in Decline?

Shark populations are in decline globally and in Australian waters. 100 million sharks are killed in worldwide fisheries each year and habitat degradation, pollution and climate change are also impacting international shark populations. Controversial shark nets and drum lines (designed to protect human populations) add further to the decline.

Sharks live a long time (20-30 years), grow slowly and take a long time to mature and reach reproductive age. This means that even if we slow the decline in shark populations now, populations will take a long time to recover.

 

Sharks Facts QuizShould I Be Scared of Sharks in Australia?

No! We don’t think you should be scared of sharks. The ocean is their home and when we visit their home we need to be very aware and respectful of them.

  • On average, one person a year is killed in a shark attack in Australia.

To put things in perspective…

  • 5 people die from falling out of bed
  • 10 people are struck down by lightning
  • 1,100 are killed on our roads

  • Sharks have eyelids but they do not blink
  • Sharks do not see in colour
  • 10% of shark species are bioluminescent – they light up in the dark
  • 180 species of shark live off the coast of Australia – 400 species worldwide
  • Bull sharks can live in fresh and salt water
  • Some sharks lay eggs (oviparous) others give birth to live young (viviparous), and some are a combination of these two, they start life inside their mother as an egg, hatch inside her and then are born live (ovoviviparous)
  • Egg laying sharks lay egg cases known as mermaid’s purses
  • Unlike humans, sharks breathe through gills, so their nostrils are purely dedicated to smelling
  • Sharks are able to detect blood from 5 km
  • Sharks can identify which of their two nostrils have picked up a scent – enabling them to determine the direction to swim to find food
  • Some species of shark can survive for up to 3 months between meals
  • Sharks can sense vibrations from 3 kilometres away

 

What Can I Do to Help Protect Sharks?

  • Educate yourself and your friends
  • Share your love of sharks on your social media channels
  • Join a volunteer shark conservation organisation like sharkconservationorg.au, marineconservation.org.au, seashepherd.com.au (make a donation if you can)
  • Join a beach clean or just clean as you go!
  • Buy sustainable seafood and check restaurants have done so. Avoid flake at the Fish & Chip shop as it may be endangered shark
  • Ask politicians to support ocean acidification research

Ocean Life Education is passionate about protecting all marine animals and focusing on the important role sharks play in our oceans.  We aim to separate fact from fiction when it comes to the most feared fish in the sea.
