7 differences between the Great White Sharks and Bronze Whaler Sharks

Shark cage diving off the shores of Cape Town is a bucket-list adventure for many travelers to South Africa.

While the great white shark often steals the spotlight, another species commonly seen in these waters is the bronze whaler shark (also known as the copper shark). Though both species can appear similar to the untrained eye, they are quite distinct in appearance and behavior.

Here are seven differences to help you tell them apart.

1. Size and Appearance

Great whites are among the largest predatory fish in the ocean and have been known to reach lengths of up to 6 meters and weigh over 2 tons. Bronze whaler sharks grow to 3.3 meters.

While great whites have a stocky build and conical snout, bronze whalers are slimmer with a long, pointed snout that is moderately rounded and broad. A characteristic bronze sheen on their dorsal side, making them distinctive to spot when shark cage diving in Cape Town. The Great whites are grey on top and with a white underside, a trait called countershading that provides camouflage by blending with the water.

2. Teeth and Feeding

Great white sharks have large, serrated, triangular teeth designed for tearing through flesh and bone, perfect for preying on seals, smaller shark species, and large fish. Bronze whalers, by contrast, have narrower, hook-shaped teeth suited for gripping slippery prey like schooling fish and squid.

Their feeding styles reflect this difference, with great whites often using a powerful ambush strike and bronze whalers relying on swift, coordinated movements.

3. Hunting Behaviour

Great whites are solitary hunters, ambushing prey from below with explosive bursts of speed. This is why historical sightings when shark cage diving in Cape Town often involved dramatic breaches as they hunted seals.

Bronze whalers, however, are social feeders that hunt in groups, especially when schools of fish are present. They make an excellent species of shark to cage dive, as they arrive in numbers.

4. Geographic Range

Both species inhabit South African waters, but their ranges differ. Great whites are widespread, roaming vast stretches of the ocean and undertaking long migrations between feeding and breeding grounds.

Bronze whalers prefer temperate coastal regions and are often more predictable, making regular seasonal appearances off South Africa’s coastline.

5. Interaction with Cage Divers

Great whites are iconic in the shark cage diving industry, drawing thrill-seekers hoping to glimpse their immense power. But sightings of great whites near Cape Town have become less frequent in recent years.

Bronze whalers have stepped in as the main attraction and offer consistent encounters. They tend to be more active around cages and provide longer viewing opportunities.

6. Conservation Status

The great white is listed as vulnerable by the IUCN due to overfishing and habitat loss worldwide. Bronze whalers are also under pressure, classified as near threatened, largely because they are targeted in commercial fisheries.

Understanding these differences can heighten a traveler’s appreciation for conservation efforts during shark tours.

All shark tours in South Africa collect data on every trip. This data is used to protect sharks and their habitats.

7. Role in the Ecosystem

Great whites are apex predators that help regulate populations of seals and large fish, maintaining balance in marine ecosystems. Bronze whalers, while still formidable, are mid-level predators whose group feeding impacts schooling fish populations.

Both play vital but distinct ecological roles along South Africa’s coasts.
