These are the fish that lived in prehistoric times, and managed to survive until now without much change in their appearance, so they are similar to fossils of their ancestors.... Here are the second 5-prehistoric fish,
6. Arowana
These
fish are Including a group of ancient Osteoglossids, these fish already
existed in the Jurassic period. Today, they are found in the Amazon,
and in parts of Africa, Asia and Australia. Sometimes kept as exotic
pets, arowanas are voracious predators that feed on small animals they
can catch, including birds and bats. They can jump up to 2 meters into
the air. In China, arowanas are known as "dragon fish" because of their
appearance, and they are thought to bring good luck.

7. Arapaima
These
are including close relatives with arowana, Amazonian arapaima is
sometimes considered to be the largest freshwater fish in the world.
According to early descriptions, this fish can grow up to 4.5 meters in
length, but now, the individuals who are most like this is rare and the
average adult arapaima found only 2 meter length. These slow moving
predators and feed on small fish, and anything else that can fit in
their mouth. An interesting feature of this fish is that they need
oxygen to survive. Arapaimas harmless to humans and are often hunted for
their meat, unfortunately, they are very rare nowadays. Although the
arapaima seemingly appeared in the Miocene period, but they get much
older family, the Osteoglossidae, and its origins can be traced back to
the age of dinosaurs.

8. Hagfish
According
to the fossil record, hagfish have existed for over 300 million years,
which means they've been there long before dinosaurs ruled! Found in
relatively deep waters, these animals are sometimes called slime eels,
but they are not really eels, and actually, they also can not be said of
the fish at all, according to some scientists. They are very bizarre
animals in all things, they have a skull but no backbone, and they have
two brains and almost blind. They feed at night and eat the carcasses of
large animals that fell into the sea. They naturally produce mucus that
damage the gills of predatory fish, as a result, they have virtually no
natural enemies.

9. Lancetfish
Lancetfish
clearly has a "prehistoric" appearance, with a grim face, sharp teeth
in its jaws, and the screen on the back, reminiscent of some dinosaurs
(although in lancetfish, the screen is actually a broad dorsal fin).
Even its scientific name is also similar to dinosaurs name, the
Alepisaurus ferox. Up to two meters in length, this predator is found in
all oceans except for the polar regions, very greedy, they eat small
fish and squid, and are also known to sometimes he ate members of its
own species.

10. Sturgeon
Another
survivor who survived the age of the dinosaurs, sturgeon, known as one
of the main sources of caviar; due to overfishing, these unusual armored
fish are endangered today. The largest sturgeon species can grow up to 6
meters, and the growth of the white shark.
They eat small animals from
the sea bottom and pose no danger to humans, unless provoked (although
they are big actually can kill people if they jump into the human body!) (Jump to 1st part.)
