Are catfish related to sharks? The debate about whether catfish are related to sharks has been going on for years. Some people say that cats and fish are in the same family tree, while others maintain that catfish are more closely related to sharks.
In this blog post, we will take a closer look at these two creatures and try to determine which one is more closely related to the other.
Spoiler alert: Sharks are more closely related to catfish than most people think! Keep reading to find out why.
Are Catfish Related to Sharks? (Is Shark Related to Catfish?)
No, catfish are not related to sharks. One similarity that both species have is that they have no scales on their skin. Catfish evolved from a different ancestor than sharks and have developed many unique features, including taste buds all over their body (which help them locate food in murky water) and a barbell on their nose (used for sensing movement in the water).
Sharks are one of the oldest surviving fish species, and catfish are one of the most diverse freshwater fish families.
Are Catfish Freshwater Sharks? (Catfish Vs Shark)
No, catfish are not freshwater sharks. As we mentioned, they come from a different ancestor and have many unique features that set them apart from sharks. One of the main differences is that catfish live in freshwater habitats, while sharks live in saltwater habitats.
Catfish are also bottom-feeders, meaning they feed on the bottom of the food chain. Sharks are top predators and have a very different diet.
Why Are Some Catfish Called Sharks?
Some species of catfish are called sharks because of their predatory behavior and their ability to grow to large sizes. One of the most popular examples is the wels catfish, which can grow up to 6 feet (1.8 meters) long and weigh over 200 pounds (90 kg)!
Other examples include the bullhead catfish and the Irrawaddy catfish. While these fish may be called sharks, they are not related to sharks.
What Is the Closest Living Relative to Sharks?
The closest living relative to sharks is the lamprey eel. These creatures share a common ancestor with sharks and are thought to have split from the shark lineage around 500 million years ago.
Lampreys are jawless fish with sucker-like mouths and rows of sharp teeth. They connect themselves to other fish and feed on their blood.
So there you have it! Sharks are more closely related to catfish than most people think. Next time you’re asked the question, “Are catfish related to sharks?” you can now give an informed answer.
Catfish Shark Freshwater

Catfish Shark Size
The average size of a catfish shark is around 3 feet (1 meter). However, some specimens have been known to grow up to 6 feet (1.8 meters) long! These fish are native to Africa and Asia and can be found in freshwater rivers and lakes.
Different Types of Sharks (Shark Catfish Species)
There are many sharks, but the most common type is the great white shark. Other popular types of sharks include the hammerhead shark, the tiger shark, and the mako shark.
There are also many different types of shark catfish. Some of the most popular types of shark catfish include the wels catfish, the bullhead catfish, and the Irrawaddy catfish.
Do Sharks Eat Catfish?
No, sharks do not eat catfish. Most sharks are not even interested in eating fish. Sharks are predators and usually prefer to eat other marine animals, such as seals, turtles, and other sharks.
There are a few exceptions to this rule. Some shark species, such as the tiger shark, will occasionally eat fish. However, most sharks do not regularly eat fish and are not a major threat to catfish populations.
What Fish Are Catfish Related To?
There are many types of catfish, but they can be divided into two groups: those that live in fresh water and ones that dwell exclusively in saltwater. The more common type is the latter group which includes sea basses as well! All of these fish are related to each other.
Regarding species, the term “catfish” refers to a very large and diverse group of fish. This group includes both freshwater and saltwater fish. Some of the most popular types of catfish include the bullhead catfish, the channel catfish, and the blue catfish.
How Do Catfish reproduce?
Catfish reproduce by laying eggs. The female catfish will lay her eggs in a nest she has built. The male catfish will then fertilize the eggs. Once the eggs are fertilized, the female will leave the nest, and the male will stay to protect the eggs.
The eggs will hatch after about a week. The baby catfish, or fry, will then be on their own. They will need to find food and shelter to survive.
What Fish Are Related to Sharks?
Sharks, stingrays, and skates are all part of a larger group of fish called Chondrichthyes. This group is characterized by their cartilaginous skeleton, which is made of flexible connective tissue instead of bone. The Chondrichthyes also include whales and dolphins.
The two main subgroups within the Chondrichthyes are the Elasmobranchii and Holocephali. The Elasmobranchii includes sharks, rays, and skates. The Holocephali includes the whale shark and dolphins. While sharks get a lot of attention, there are more rays and skates in the world than there are sharks.
What Did Sharks Evolve From?
Sharks evolved from jawless fish known as ostracoderms. These fish are thought to have first appeared in the late Ordovician period, about 490 million years ago. Jawless fish were armored with bony scales called osteoderms. They were a very successful group and diversified into many different types of fish. Some, such as the lampreys, still exist today.
The first sharks appeared about 420 million years ago during the Silurian period. They were very similar to the modern sharks we see today. Sharks have changed very little throughout their evolution and are some of the most primitive living fish species.
What Animals Are Similar to Sharks and Why?
What Are Sharks Closest Relatives? Some animals are similar to sharks, most notably skates and rays. Both skates and rays belong to the same taxonomic superorder as sharks (the Selachimorpha) and share many key anatomical features with them.
For example, all three groups have skeletal systems composed mostly of cartilage rather than bone. Additionally, skates and rays (like sharks) have large pectoral fins that they use for locomotion and a wide variety of other specialized features that enable them to be successful predators in their respective environments.
However, one key difference between skates and rays is that the latter group has evolved to have a flattened body shape, whereas skates tend to be more laterally compressed. This flattened body shape helps rays to glide through the water with ease and is one of the major reasons why these animals are often confused with sharks.
Are There Any Dangers to Humans From Catfish?
No, catfish are not a danger to humans. They are quite docile and pose no threat whatsoever. There have been no reports of catfish attacking or harming humans in any way.
The only thing you need to be careful of when handling catfish is their barbs. These barbs are located on the fins and can be quite sharp. They can easily puncture your skin and cause pain if you are not careful. Other than that, catfish are harmless to humans and make great pets.
What Shark Looks Like a Catfish?
The Iridescent shark (Pangasianodon hypophthalmus) is a species of fish in the family Cincinnati clade. It is the only living member of its genus. The Iridescent shark was first described in 1822 by French naturalists Géographe Pierre Peron and Lesueur.
Its specific epithet hypothalamus comes from the Greek ὑπό (hypo-, meaning “under”) and (ophthalmos, meaning “eye”).
The Sharksucker (Echeneis naucrates) is a species of fish in the family Remoraidae, making it the only living member of its genus. It is found in most tropical waters around the world.
Is Dog Fish a Shark?
Dogfish are small, bottom-dwelling sharks that live along the northern Pacific and Atlantic coastlines. They can travel long distances with their habitat ranging from dark depths at 3k feet to shallower waters receiving ample sunlight!
The biggest difference between dogfish and sharks is that dogfish have a spine made of cartilage, whereas sharks have a bone. Additionally, dogfish lack the large pectoral fins that sharks use for locomotion.
Is a Dogfish Catfish?
No, a dogfish is not a catfish. A catfish is a ray-finned fish belonging to the order Siluriformes. There are more than 3,000 different species of catfish, which makes them one of the most diverse groups of fish in the world.
Are Rays Related to Sharks?
Yes, rays are related to sharks. Both rays and sharks belong to the same taxonomic superorder (the Selachimorpha) and share many key anatomical features. For example, all three groups have skeletal systems composed mostly of cartilage rather than bone.
Additionally, rays (like sharks) have large pectoral fins that they use for locomotion, as well as a wide variety of other specialized features that enable them to be successful predators in their respective environments.
However, one key difference between rays and sharks is that the former group has evolved to have a flattened body shape, whereas sharks tend to be more laterally compressed. This flattened body shape helps rays to glide through the water with ease and is one of the major reasons why these animals are often confused with sharks.
Are Catfish and Pangasius the Same?
The pangasius is a genus of medium-large to very large shark catfish natively found in fresh water. The term “Panga” can sometimes refer to only one type, which has been commercially important for centuries.
Pangasius is typically gray or off-white, with a long eel-like body and a flattened head. They have a large mouth with prominent barbels, and their fins are often black or dark-colored.
Pangasius hypophthalmus, also known as the iridescent shark or striated catfish, is a freshwater fish species in the Cincinnati clade family.
How Big Do Pangasiidae Catfish Grow?
Mature Pangasiidae Catfish can grow up to 130 cm in length and weigh 44 pounds. They are found near the bottom of oceanic waters, at a pH level ranging from 6-7 with readings around 22°C or 26 °Fahrenheit (or 70 degrees Celsius).
Conclusion
So, are catfish related to sharks? The answer is both yes and no. Catfish and sharks share some common characteristics but also major differences. The next time you’re at the aquarium or fishing for catfish, be sure to keep these distinctions in mind!
