Why Do the Biggest Sharks Eat Tiny Animals? Shark Activities for Schools

Why Do the Biggest Sharks and Whales Eat Tiny Animals?

Celebrate Shark Awareness Month with a surprising science lesson

When students imagine the biggest animals in the ocean, they often picture fierce predators with enormous teeth. So they’re usually amazed to discover that the largest shark in the world – and even the biggest whales – feed on some of the smallest creatures in the ocean. So, why do sharks eat plankton

It sounds impossible. Why would a 12-metre whale shark or a 30-metre humpback whale spend its day eating animals no bigger than your fingernail?

This fascinating question is the perfect way to spark curiosity during Shark Awareness Month (July) and Shark Awareness Day, while exploring food chains, adaptations and marine ecosystems.

Meet Queensland’s Gentle Giants

Queensland waters are home to some incredible marine animals, including species that rely on tiny marine life to survive.

🦈 Whale Shark

Despite being the largest fish on Earth, whale sharks feed almost entirely on plankton, tiny fish eggs and small schooling fish.

Instead of chasing large prey, they simply swim slowly through the water with their enormous mouths open, filtering thousands of litres of seawater every hour.

Although whale sharks are occasional visitors to South East Queensland, they are more commonly seen around the Great Barrier Reef and Ningaloo Reef.

Is a whale shark a shark?

🐋 Humpback Whale

Every winter, thousands of humpback whales migrate along the Queensland coast, passing places like Noosa, Mooloolaba and the Sunshine Coast.

These enormous mammals also feed on surprisingly small animals – mainly krill and other tiny crustaceans during their time in Antarctic waters before migrating north to breed.

Their baleen plates act like giant sieves, allowing them to trap huge amounts of food while letting seawater escape.

So…Why Eat Tiny Animals?

The answer is simple:

There are billions of them!

Tiny marine organisms like plankton and krill are among the most abundant living things on Earth.

Instead of hunting one large meal, whale sharks and baleen whales efficiently collect thousands – or even millions – of tiny animals in every mouthful.

Scientists call this filter feeding.

It is one of the most efficient feeding strategies in the ocean.

What Exactly Is Plankton?

Many students think plankton is just one type of animal.

In fact, plankton describes any tiny organism that drifts with ocean currents.

Some plankton are microscopic plants called phytoplankton, while others are tiny animals known as zooplankton.

These organisms form the foundation of almost every marine food chain.

Without plankton, there would be no fish, whales or sharks.

Amazing Ocean Adaptations

Filter-feeding animals have evolved remarkable adaptations.

Whale Sharks

Huge mouths over one metre wide
Tiny teeth that are rarely used
Special filtering pads that trap food
Gentle swimming behaviour

Baleen Whales

No teeth
Hundreds of baleen plates made from keratin
Powerful tongues
Huge expandable throats for gulp feeding

These adaptations help them collect enormous amounts of food while using very little energy.

Queensland Connection

Did you know?

Each winter, South East Queensland becomes one of Australia’s best places to observe humpback whales during their annual migration.

Students may even spot whales from:

Noosa National Park
Point Lookout (North Stradbroke Island)
Cape Moreton
Mooloolaba coastline
Coolum and Peregian beaches

This makes Shark Awareness Month the perfect time to compare two of the ocean’s most impressive filter feeders – the whale shark and the humpback whale.

Classroom Activities (Years 7–9) – See Activity Handout Below

1. Bigger Isn’t Always Scarier

Show students pictures of:

Great White Shark
Whale Shark
Humpback Whale

Ask:

Which one do you think eats the biggest prey?

Students are often surprised by the answer.

2. Build a Marine Food Chain

Challenge students to create a food web beginning with:

Sunlight → Phytoplankton → Zooplankton → Small Fish → Larger Fish → Sharks

Then compare it with:

Sunlight → Phytoplankton → Zooplankton → Whale Shark

Sunlight → Phytoplankton → Krill → Humpback Whale

Discuss how different species occupy different roles within marine ecosystems.

3. Design a Filter Feeder

Ask students to invent their own giant marine animal.

They should decide:

How does it collect food?
What adaptations does it need?
Where does it live?
What does it eat?
How does it survive?

Students can label their design and explain how their adaptations help them feed efficiently.

4. STEM Challenge: Can You Filter Like a Whale?

Using everyday classroom materials, students design and test a simple filter that separates different-sized particles from water.

Encourage them to investigate:

Which materials worked best?
What particle sizes were captured?
How is this similar to baleen or a whale shark’s filtering system?

This hands-on investigation introduces engineering design, observation and scientific inquiry.

Why Sharks Matter

Shark Awareness Month is about much more than changing people’s perceptions of sharks.

It is an opportunity to help students understand that sharks perform many different ecological roles.

While some species are top predators, others – like the whale shark – are gentle filter feeders that depend on healthy plankton populations and balanced marine ecosystems.

Protecting sharks helps protect the entire ocean.

Shark Activities for Early Years

Sharks are often one of the first ocean animals children recognise. Their unique features and behaviours make them ideal for early learning ocean activities.

Shark Sensory Play Activity

Set up an ocean-inspired sensory tray using water, sand, toy sharks, shells, blue stones or glass pebbles, and green ribbons to represent seaweed.

Encourage children to explore and describe their discoveries using words such as fast, sharp, smooth, swim, ocean.

This sensory play ocean activity supports language development, imaginative play and early science skills.

Shark Movement Activity

Invite children to move like different ocean animals:

A fast-moving shark
A slow turtle
A large whale
A tiny fish

This activity promotes gross motor development while reinforcing descriptive vocabulary.

Shark Storytelling Activity

Read a shark-themed book such as Clark the Shark by Bruce Hale and ask children:

Where does the shark live?
What does it eat?
How does it move?

Children can then create their own stories through drawings and discussion, supporting early literacy and ocean learning activities.
