1. Coelacanth
Coelacanth is the most famous of all "living fossil" and deserve to be # 1 in this list, because this is the best example of a Lazarus taxon, this is supposed to be long extinct animals and unexpectedly found alive today. These 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, specimens have been seen and photographed, and even the second coelacanth species found in Indonesia in 1999. This is a large predator fish, 2 meters in length, they feed on small fish, including small sharks, and are usually found in the deep dark waters.
2. Polypterus Senegalus
Fish Africa is often called the "dinosaur eel", because of their appearance and serrated dorsal fin. They're actually not an eel, but family members Bichirs. Although often sold as exotic pets "dinosaur eel", they can survive out of water for long periods of time as long as they remain moist skin.
3. Alligator Gar
This thick scaly predators found in the U.S. south, north and east of Mexico, becoming the largest freshwater fish in North America. Alligator Gar can grow to 4 feet and weigh up to 200 kg. Alligator Gar are so called because they look like reptiles, alligators and long jaw, has 2 sides of sharp teeth. Alligator Gar are voracious predators and have been known to be dangerous to humans, although not yet confirmed death from the Alligator Gar has been recorded to date. Gar is one of the oldest fish alive today.
4. Sawfish
These animals are the victims of the Cretaceous period, and can be found either at sea or in rivers at a depth of 100 km with a length of 7 meters, this fish looks like a shark with a mouth that resembles a chainsaw, but Sawfish not included in the only similar species of shark . Sawfish is actually not a race of sharks, stingrays but including race, from under his body shape that is flat, unlike the shark bottom leaner streamlined shape that allows sharks to swim fast in water, and Sawfish have a small mouth parallel to the lower body are fused with his body. Sawfish fins also have a front parallel to the bottom.
5. Arapaima
Overview of fish is similar to the Arowana fish, Arapaima Amazon regarded as the largest freshwater fish in the world. According to the initial description, can grow up to 4.5 meters, but until recently, large Arapaima is rarely found and most adults arapaimas average size of 2 meters. Arapaima eat small fish, crustaceans and whatever small animals can get into their mouths. One interesting feature of this fish are inhaling oxygen from the air for survival. Arapaimas not cause harm to humans and are often hunted for their meat, Arapaima unfortunately very rare today.
6. Sturgeon
Sturgeon has been known as one of the main sources of caviar (fish eggs) because of being overfished, the population is being threatened at this time. Largest sturgeon species can grow to 6 meters, equal to the white shark, Sturgeon eat small animals from the sea and poses no danger to humans, unless provoked.
7. Frilled Shark
This deep-sea predator, one of the most primitive sharks living today, is a relic of the Cretaceous period, frilled shark can grow up to 2 meters (size larger than the female shark shark man) and they live in deep water, where they mostly eat squid. They are harmless to humans, and actually, sharks spend their entire lives without seeing human beings as they live in the deep ocean. Only a dead specimen usually seen on the surface and recorded by fishermen or scientists.
8. Arowana
Osteoglossids (arowana), these fish already exist in the Jurassic period. Today, they are found in the Amazon, and in some parts of Africa, Asia and Australia. Sometimes kept as exotic pets. Arowana is a fish that eat small animals and worms that they can get, including birds and bats which they catch while flying, arowana can also jump up to 2 meters to the air. In China, the arowana is known as "fish-dragon" because of their appearance, and they are considered a sign of good fortune.
9. Lancetfish
Lancetfish known as a fish that already exist in prehistoric times, teeth and sharp look out on the jaw and fins on its back. Lancetfish Up to two meters long, this predator was found in all oceans except the polar regions, Lancetfish eat small fish and squid, and Lancetfish also eat the big fish.
10. Hagfish
According to records, Hagfish has been around for more than 300 million years. Found in waters that are relatively deep, this animal is sometimes called slime eels, but they are actually not an eel, and in fact they do not even like fish at all. According to some scientists, they are a very strange animal in all respects, they have the skull but did not have a backbone, and they have two brains.
