Top 5 Prehistoric Fish Alive Today

Hagfish
According to the fossil record, hagfish have existed for over 300 million years, which means they were already old when dinosaurs took over the world! Found in relatively deep waters, these animals are sometimes called slime eels, but they are not really eels, and actually, they may not even be fish at all,
according to some scientists. They are very bizarre animals in all regards; they have a skull but lack a 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 owe their “slime eel†nickname to the fact that they produce a slimey substance to damage the gills of predatory fish; as a result, they have virtually no natural enemies.

Lancetfish
The lancetfish has a very obvious “prehistoric†appearance, with those fierce-looking, sharp teeth on its jaws and the sail on its back, reminiscent of that of some dinosaurs (although, in the lancetfish the sail is actually an enlarged dorsal fin). Even its scientific name has a dinosaurian sound to it (Alepisaurus ferox). Up to two meters (6′ 6″) in length, this predator is found in all the oceans except for polar regions; very voracious, it feeds on smaller fish and squid, and has known to feed on members of its own species sometimes.

Arowana
Belonging to the ancient group of the 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 any small animal they can catch, including birds and bats which they catch in mid flight (they are able to leap up to 2 meters (6′ 6″) into the air). In China, arowanas are known as “dragon-fish†due to their appearance, and they are thought to be harbingers of good luck.5

Frilled Shark
This deep sea predator, one of the most primitive sharks alive today, is 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 being larger than males) and they live in deep waters, where they feed mostly on squid. They are not dangerous to humans, and as a matter of fact, most frilled sharks spend their whole lives without seeing a human being. Only dead or dying specimens are usually seen and recorded by fishermen or scientists.Frilled Shark

Sturgeon
Another survivor from the age of dinosaurs (they were already around in the early Jurassic), the sturgeon is well known for being one of the main sources of caviar (which is made out of their roe or egg masses); due to overfishing, these magnificent, armored fish are sadly endangered nowadays. The largest sturgeon species can grow up to 6 meters (19′ 7″) long, being 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 big that they have hurt, and even killed, people unintentionally by leaping out of the water and landing on boats!)
