World Top 5 Monster Fishes.

 

                                                            1.Piranha 

                                     

                      

        🦈 A piranha or pirana  is one of a number of freshwater fish in the family Serrasalmidae,or the subfamily Serrasalminae within the tetra family, Characidae in order Characiformes.These fish inhabit South American rivers, floodplains, lakes and reservoirs. Although often described as extremely predatory and mainly feeding on fish, their dietary habits vary extensively, and they will also take plant material,leading to their classification as omnivorous.Piranhas are indigenous to the Amazon basin, in the Orinoco, in rivers of the Guianas, in the Paraguay–Parana, and the Sao Francisco River systems, but there are major differences in the species richness. 

                         In a review where 38–39 piranha species were recognized, 25 were from the Amazon and 16 from Orinoco, while only three were present in    Paraguay–Parana and two in Sao  Francisco.Aquarium  piranhas have been unsuccessfully introduced into  parts of the United States.Piranhas have one of the strongest bites found in bony fishes. Relative to body mass, the black piranha produces one of the most forceful bites measured in vertebrates.

                            

                                        2.Tiger Fish            

                         

                              

          🦈 African Tiger fish is most dangerous fish category in the world. Several species belonging to the genus Hydrocynus of the family Alestidae  are referred to as "tigerfish", and are particularly prized as game fish.                                 These African fish are found in many rivers and lakes on the continent and are fierce predators with distinctive, proportionally large teeth.The goliath tigerfish is among the most famous tigerfish. The largest one on record is said to have weighed 70 kg.The name "tigerfish" has occasionally been used for a species of cichlid in the genus Rhamphochromics. The species is large, silver-coloured, and individuals typically have one or more black lines running the length of either flank. These fish are native to Lake Malawi in Africa. Like the other African tigerfish species, they are famed for possessing large, prominent teeth, and they are known to attack humans.

                                    3.Payaara.        

                                   
                    

    

          🦈The Vampire fish (Danionella dracula) is a species of tropical danionin fish from the cyprinid family. It is a freshwater fish endemic to Myanmar.A close relative is Danio rerio, the zebrafish of aquariums. It is named dracula after its unusual "fangs"; male dracula fish have producting tooth-like bones stemming from their jawbones. Males have been observed using their fangs to spar with other males.           

                                                                                                                       Dentified in April 2007 from specimens shipped to the United Kingdom in a consignment of aquarium fishes, the dracula fish has so far only been found in the wild in a small stream at Sha Du Zup between Mogaung and Tanai in northern Myanmar.It is a colourless miniature species and grows to a maximum size of around 17 millimetres (0.67 in).The fish has an elongate body with a large head and eyes. Dracula fish lack scales and the upper body is dominated by the jaws on large males. Much of the fish's structure is cartilaginous: it has 44 fewer bones than the zebrafish, and thus it is translucent and appears similar to larval forms.The natural diet of the dracula fish is unknown but in captivity it eats shrimp larvae, small nematodes and fish flakes. Close relatives of the fish feed upon small crustaceans and invertebrates. 

                                                    

                                             

                                                      4.Aligator Gar.

               

                                   

                   
       🦈The alligator gar is a ray-finned euryhaline fish related to the bowfin in the infraclass Holostei.It is the largest species in the gar family, and among the largest freshwater fish in North America. The fossil record traces its group's existence back to the Early Cretaceous over 100 million years ago. Gars are often referred to as "primitive fishes", or "living fossils" because they have retained some morphological characteristics of their early ancestors, such as a spiral valve intestine, which is also common to the digestive system of sharks, and the ability to breathe both air and water.Their common name was derived from their resemblance to the American alligator, particularly their broad snouts and long, sharp teeth. Anecdotal evidence suggests that an alligator gar can grow up to 10 ft (3.0 m) in length.

                                  5.Arapaima.  

                                     

         

       🦈Arapaima is giant river monster fish in world. 

Arapaima can reach lengths more than 2 m (6 ft 7 in), in some exceptional cases even exceeding 2.6 m (8 ft 6 in) and over 100 kg (220 lb).The maximum recorded weight for the species is 200 kg (440 lb), while the longest recorded length verified was 3.07 m (10 ft 1 in). Anecdotal reports suggest that specimens as long as 4.57 m (15 ft 0 in) exist, but verification is deemed impossible, and thus considered questionable. As a result of overfishing, arapaima more than 2 m (6 ft 7 in) are seldom found in the wild.
