Life on Earth began hundreds of millions of years ago, many species were extinct long ago and only known through fossils deep underground. However, there are still a few animals that have evolved to match the changes of nature over millions of years and exist until now.

1. Goblin sharks

Goblin sharks are also called Goblin sharks. They are a deep-sea shark, ugly and prominent, with a long beak-like nose.

The whole body Goblin sharks are pink and the jaws are elastic with many sharp teeth, suitable for grinding food. This is considered one of the characteristics that distinguish this shark from many other species.

Goblin shark is one of the oldest surviving predators, this species once existed at the same time as Megalodon, a giant marine shark living about 30 million years ago. Other comments suggest that this species is similar to Helicoprion shark that lived 250 million years ago.

2. Giant river stingray with poisonous spines

This giant stingray is often present in rivers in Southeast Asia. This is one of the largest freshwater fish species in the world with a weight of 500 - 600kg. This stingray has an oval shape with a length of about 2m, with a long tail that has many serrations.

This stingray was popular in 2006 when using his poisoned tail to kill the famous Australian naturalist Steve Irwin. According to scientists, this species has existed since the Jurassic period, about 100 million years ago.

Currently, this species is under threat of extinction when faced with overfishing and shrinking habitat. In many Southeast Asian countries, especially Thailand, it is necessary to take measures to protect these rays.

3. Wrinkled shark

Wrinkled shark is one of the oldest sharks that has survived to this day and only two individuals of wrinkled sharks have been found in Japanese waters.

The shark mainly lives in deep waters of 600-1,000 meters and is considered by living researchers as living fossils in the ocean for at least 95 million years.

The function of this fish has about 300 sharp teeth such as fishhooks and mouths that can open very wide to attack prey, including prey larger than body length. Currently, the International Union for Conservation of Nature has placed this species on the list of threatened species and needs strict protection to avoid extinction.

4. Rocket crocodile

Rocket Crocodile is a large freshwater fish found only in North America. This fish stands out with the body of the fish, and the head looks like a crocodile with a long muzzle and many sharp teeth.

With a maximum length of 3 meters and a weight of 91kg, it is possible to live for 70 years and a high tolerance for terrestrial activity for 2 hours is what makes the crocodile a powerful fish.

Tilapia shrimp was found in 2010 in the Scottish coast with many living individuals. The researchers say these individuals have not changed compared to when they lived 200 million years ago.

With a length of about 10cm and many mysteries that scientists have not yet studied, this is considered a living fossil and will provide much information about ancient crustaceans with complete differences. Full compared to current species.
