Types Of Freshwater Sharks: The Sharks Of Rivers And Lakes


Only a select few species of Fresh Water Sharks may be found across the globe. These one-of-a-kind species have developed in order to be able to survive in freshwater ecosystems like rivers and lakes. Because freshwater does not contain any salt, it is extremely challenging for sharks to make the change from living in saltwater to living in freshwater.

Store Salt Properly

Without being able to store salt properly within their bodies, sharks run the risk of having their Shark Aquarium, which would ultimately lead to their demise. Because of this, the majority of saltwater shark species are unable to swim effectively in freshwater environments.

The Ability To Store Salt

On the other hand, certain species have evolved the ability to store salt and recycle it within their body. This means that there are Fresh Water Sharks living in lakes and rivers all over the world. We are going to have a look at a few different species of freshwater sharks as well as how to recognize them.


The Speartooth Shark, scientifically known as Glyphis, has the ability to live in both saltwater and freshwater environments. Both saltwater and freshwater settings are home to the enigmatic Fresh Water Sharks, also known as Glyphis. This extremely uncommon species of freshwater shark is indigenous to the regions of West Papua, Papua New Guinea, and Northern Australia.

Riverbeds Of Tropical Rivers

They are most frequently seen on the riverbeds of tropical rivers and in estuaries with swift currents. In order to conserve energy while they are eating on fish and crustaceans, speartooth Fresh Water Sharks  ride the tidal currents upstream, which allows them to travel further. This species of hardy shark can reach a maximum length of 9.8 feet and is distinguished by having a particularly broad head, a snout that is flattened, and eyes that are quite small.

Spear-Shaped Lower Teeth

They have around 29 rows of teeth on both their upper and lower jaws, making up the entirety of their mouths. This type of Fresh Water Sharks gets its name from the spear-shaped lower teeth, which are narrower than the top teeth and have serrations on them. The upper teeth of the Speartooth shark are what give the shark its name.

The Ganges Shark

There is a common misunderstanding that the Ganges Fresh Water Sharks  (Glyphis Gangeticus) is the more hazardous Bull Shark. The Ganges shark is a marine species that is considered to be in a critical endangered status and can typically be found in the rivers Ganga, Hooghly, Mahanadi, and Brahmaputra in India.

The Depths Of Rivers

Because they are never discovered anywhere other than at the depths of rivers and other freshwater ecosystems, this particular Fresh Water Sharks is referred to as a true river shark.

The Ganges shark is easily identifiable thanks to its uniformly dark gray or brown coloring.

They can be recognized by their two dorsal fins that do not have spines and their wide, spherical snouts.

The Dangerous Bull Shark

Additionally, they have relatively small eyes because of the low visibility of their natural environment. People have a common misconception that this species poses a risk to human life; nevertheless, these sorts of Fresh Water Sharks are sometimes confused for the dangerous Bull shark. Because the Ganges shark is not nearly as common and because its teeth are adapted to puncture fish rather than mammals, it is extremely improbable that it will attack a person.

Top Three Shark Species

One of the top three shark species that are known to attack humans is the bull shark, also known as Carcharhinus leucas. Both saltwater and Fresh Water Sharks environments are frequent habitats for the lethal Bull shark, which may be found all around the world.

Most Exceptional Kinds Of Sharks

It is one of the most exceptional kinds of sharks since it is one of the few species that is able to live in both freshwater and saltwater habitats. The salt concentration in their blood is just fifty percent of what it is in other sharks. This variety of freshwater shark is large, stocky, and vicious, and it frequently inhabits areas where people do not anticipate finding any risk.

Spending Time In Shallow Waters

On the other hand, despite being able to travel thousands of miles upriver, bull sharks are one of the most common types of freshwater sharks found in lakes. They spend a lot of time in shallow waters, which are places where people are more prone to swim, and because of this, they are sometimes misidentified as food.

The Great White Shark

Due to the fact that their general shark characteristics are not especially prominent, identifying a Bull shark can be a very difficult task. This is the reason why people frequently confuse them with the Ganges River shark and even the Great White shark. The Fresh Water Sharks , in contrast to many other species of shark, is considered to be one of the best sharks for aquariums since it is able to live a contented and long-lasting life when kept in captivity.

Borneo River Shark

The Borneo River Shark, scientifically known as Carcharhinus Borneensis, is so uncommon that it is frequently referred to as the Mythical Shark. The Borneo River Shark is one of the rarest types of freshwater sharks in the world, and it can only be found in the Kinabatangan River in Sabah, which is located in Malaysian Borneo.

Sharks Known As Carcharhinidae

They belong to the family of sharks known as Carcharhinidae, sometimes known as the Requiem family, and may typically be found in warm tropical seas. This particular type of freshwater shark is notable for its slender build and diminutive size, reaching a maximum length of just 2 feet.

Dorsal Fins Of This Fish

The dorsal fins of this fish have a darker coloring than the rest of the body, which makes them easier to identify. Bony fishes, including sardines and tuna, make up the majority of the Borneo River Shark’s diet. This is because the shark’s teeth are extensively serrated.
