The balloon shark (Cephaloscyllium sufflans) is a special type of catshark. It belongs to the family called Scyliorhinidae. This shark lives only in the southwestern Indian Ocean, near South Africa and Mozambique.
It lives on the ocean floor, usually over sandy or muddy areas. You can find it at depths from 40 to 600 meters (about 130 to 2,000 feet). This shark has a thick body, a wide, flat head, and a short tail. A cool thing about it is the small, flap-like skin pieces in front of its nostrils. Its back is light gray with faint darker saddle-like markings.
Just like its name suggests, the balloon shark can puff itself up! It fills its body with water or air to scare away predators. It eats different kinds of crustaceans like lobsters and shrimp, plus cephalopods (like squid), and other fishes. Female balloon sharks lay egg cases, usually two at a time. Sometimes, these sharks are accidentally caught by fishing boats, but their numbers seem okay for now. Because of this, they are listed as "Near Threatened" by the International Union for Conservation of Nature (IUCN).

Meet the Balloon Shark: What Is It?
The balloon shark is a fascinating creature of the deep sea. It's known for its unique ability to inflate its body. This defense mechanism makes it look much bigger and harder to swallow for predators.
How Big Do Balloon Sharks Get?
These sharks can grow up to about 1.1 meters (around 3.6 feet) long. They have a strong, firm body. Their head is wide and flat, with a short, rounded snout.
What Does a Balloon Shark Look Like?
- Eyes: Their eyes are oval-shaped and placed high on their head. They even have a basic third eyelid for protection!
- Mouth: The mouth is wide and forms a big arch. When it's closed, you can still see the upper teeth.
- Teeth: Each tooth has a strong point in the middle. It also has one or two tiny points on each side.
- Skin: Their skin is thick and feels rough. This is because it's covered in tiny, triangular scales called dermal denticles.
- Color: Balloon sharks are light grayish-brown or purplish on top. Their underside is paler. Younger sharks often have clearer dark saddle marks on their back and tail.
Where Do Balloon Sharks Live?
The main home of the balloon shark is off the coast of South Africa (especially the KwaZulu-Natal province) and Mozambique. They are bottom-dwelling sharks. This means they spend their lives on the seafloor.
Their Ocean Home
They live on the continental shelf and the upper continental slope. These are the parts of the ocean floor that slope down from the land. They prefer areas with sand and mud.
Young vs. Adult Sharks
It seems that young balloon sharks are often found in shallower waters off KwaZulu-Natal. This suggests that adult sharks might live in deeper or more northern waters.
What Do Balloon Sharks Eat?
The balloon shark is a hunter of the seafloor. Its diet is varied, meaning it eats many different things.
Favorite Foods
- Lobsters and Shrimp: These crustaceans are a big part of their diet.
- Cephalopods: They also enjoy eating creatures like squid and octopuses.
- Fish: Sometimes, they will eat other bony fish and even smaller sharks or rays.
How Do Balloon Sharks Have Babies?
Balloon sharks reproduce by laying eggs. This is called being oviparous.
Egg Cases
Females lay eggs that are protected inside tough, leathery cases. They usually lay two egg cases at a time. Each egg case holds one baby shark. Scientists haven't found many of these egg cases yet. This might mean that the adults lay their eggs in deeper or more northern waters.
Baby Sharks
When they hatch, baby balloon sharks are about 20 to 22 centimeters (around 8 to 8.5 inches) long. Both male and female sharks become adults when they are about 70 to 75 centimeters (around 27 to 29 inches) long.
Balloon Sharks and People
The balloon shark doesn't have much value for fishing. Its skin might be used sometimes, but that's about it.
Accidental Catches
These sharks are often caught by accident. This happens when commercial fishing boats use large nets called bottom trawls. Even though they are caught, their numbers don't seem to be going down too much.
Protecting the Species
Because of this, the International Union for Conservation of Nature (IUCN) has listed the balloon shark as "Near Threatened." This means they are not in immediate danger, but their populations should be watched carefully. It's important to keep an eye on the fisheries that operate where these sharks live.
