10 ancient fish that are still alive

FISHWORLDs We - there are a lot of ancient fish that humans do not know. but of the millions of species of ancient fish species that are still alive today. following 10 ancient fish that are still alive today, following 10 prehistoric fish still alive more:

1.Hagfish



According to the fossil record, hagfish have existed for over 300 million years, which means they are already old when dinosaurs took over the world!
Found in the waters, these animals are sometimes called slime eels, but they do not really familia eels, and even they may not fish at all, according to some scientists, they are very bizarre animals in all regards, they have a skull but lack spine, and they have two brains. Almost blind, they feed at night on the carcasses of large animals (fish, cetaceans etc) which fall to the sea bottom
. They use their slime to produce substances Slimey to damage the gills of predatory fish, from which, they have virtually no natural enemies.
 


 2.Lancetfish



Lancetfish or fish knife (in bhs Indonesua) has a clear appearance "very prehistoric", the teeth in the jaw and the screen is very sharp on his back, reminiscent of some dinosaurs (although, in this screen lancetfish truly an enlarged dorsal fin). Even the scientific name sounded dinosaurian (Alepisaurus ferox). With a long reach two meters (6 '6 "), these predators can be found in all oceans except for the polar regions; very greedy, they feed on small fish and squid, they sometimes also eat fellow community.


3.Arowana



According to an ancient group Osteoglossids, these fish already existed in the Jurassic period. Currently, they can be found in the Amazon, and in some parts of Africa, Asia and Australia. Sometimes kept as exotic pets, arowanas are voracious predators that eat smaller animals that they can catch, including birds and bats which they catch in mid flight (they can jump up to 2 meters (6 '6 ") into the air). At China, arowana known as "Dragon Fish" because
their appearance, and they are considered bearer good luck / good luck.

4.Frilled Shark



 There are predators in the sea, one of the most primitive sharks alive sharks alive today, they are a relic from the Cretaceous period, when dinosaurs ruled the Earth. Seldom seen alive, and only recently filmed for the first time, the frilled shark can grow up to 2 meters (6 '6 ") (with females larger than males) and they live in deep water, most of the food they are squid. they are not harmful to humans, and in fact revealed, sharks have spent their entire lives without seeing a human. moment Only dead or dying specimens can be seen and recorded by fishermen or scientists.

5.Sturgeon

The fish already in the early Jurassic, the sturgeon is well known as one of the main sources of caviar (which is made ​​of eggs or egg masses); due to overfishing, armored fish this magnificent extremely endangered today. Largest sturgeon species can grow up to 6 meters (19 '7 "), as large as most great white sharks, they feed on small animals from the sea bottom and pose no danger to humans, unless provoked (although they are so large, they do not threaten humans, even hunted and hurt, and even killed by people who do not responsible!)

  6.Arapaima  

They are a close relative to the arowana (see # 8), the Amazonian arapaima is sometimes considered to be the largest freshwater fish in the world. According to early descriptions, they can grow up to 4.5 meters (14 '8 ") in length, but this time, big fish like this seldom found and most adult arapaima is the average length of 2 meters (6' 6"). This slow-moving predators that prey on small fish, crustaceans and all the small animals that can fit in their mouths. One of the highlights of this fish is that they need to breathe air, like a cetacean, in order to survive. Arapaima pose no danger to humans and are often hunted for their meat, unfortunately, they are very rare nowadays. Arapaima which appeared in the Miocene period, has many old families, Osteoglossidae, and therefore its origins can be traced back to the age of dinosaurs.

7.Saw Shar

 This animal is a victim of the Cretaceous period, and can be found either in the sea or in rivers and creeks, and has been found up to 100 km inland. With a length Up to 7 meters (23 '), "Saw" and they are the weapon of sensory organ, covered on electro-sensitive pores which allow it to sense prey despite a very difficult sight though. Although generally good, sawfish can become extremely dangerous if provoked. Based on an extraordinary fossil, we know that the giant prehistoric sawfish may be a staple food for the largest carnivorous dinosaur, Spinosaurus, part of the spine of the fish was found stuck between the dinosaur's teeth.

 8.Alligator Gar

 Great thick scaly predators are found in the southern U.S., northern and eastern Mexico, being the largest freshwater fish in North America (although it sometimes wanders into the sea). They can grow up to 4 meters (13 ') long and weigh up to 200 kg (440 pounds). Gator gars so they nicknamed, because of their appearance like reptiles with long jaws, armed with two rows of sharp teeth. They are voracious ambush predators and have been known as a straight man Biter superior, but no confirmed record of causing death due to current Gator Gars. Gars are among the oldest fish alive today, their origin can be traced back to the Cretaceous period.
9.Polypterus Senegalus

African fish are often called the dinosaur eel, because their appearance resembles a reptile with a serrated dorsal fin, reminiscent of some dinosaurs were pungunggnya spiked. But they do not include familia eels, they are members of Familia bichir. They are often sold as exotic pets, dinosaur eels are often out of the fish tank (aquarium) them.They can survive out of water for long periods of time as long as their skin remains wet, which enables them to wander far from the tank (Aquarium) them.

10.Coelacanth

Coelacanth is the most famous of all "living fossils" and deserves to be # 1 on this list, as this is the best example of a Lazarus taxon, these are animals that should have been long extinct. The fish should have been extinct in the Cretaceous period, along with the dinosaurs, but in 1938, a live specimen was caught in South Africa. Since then, examined more specimens have been seen and photographed, and a second coelacanth species was even found in Indonesia in 1999. This is a large predatory fish, with a length of 2 meters (6 '6 "), they feed on smaller fish, including small sharks, and are usually found in deep, dark waters. Though rarely captured and consumed because it tastes awful, the king of fish this critically endangered marine populations.
