Since ancient times, the sea has always been a great mystery that challenges humanity. Giant sea monsters, while frightening adventurers, also stimulate a passion for discovery.

So what will you do if one day you encounter a strange marine creature in the depths of the ocean? Standing, gaping… or taking out a device to record this moment to document scientists?

But before you achieve the goal, let’s practice together before you have the chance to go 1-0-2!

1. Giant creature that can swim “like a human”

Images of this creature off the northern Isabela coast of the Galapagos Islands in the Pacific Ocean must have surprised many people.

Because it has swimming movements that are not much different from humans! Through research, experts said, this is a species of marine iguana.

With a body length of up to 1.8 m, this marine iguana resembles a Godzilla monster due to its enormous and peculiar size.

Wandering around to find a meal, after being full, the “monster” rose to the surface to breathe air and then moved its long tail to glide back to the ocean floor.

This marine salamander is known to specialize in eating algae and is capable of diving up to 9 meters deep.

At first glance, many people will wonder what this animal is. In fact, they are crested sharks, one of the most dangerous species in the world.

The crested shark is distinguished from other members of the family by the large size of the eye ridges and color pattern. They are usually nocturnal and live at the bottom of the Pacific and Atlantic oceans.

Measuring about 1.2 m in length, the crested shark is very fond of rocks and vegetation, where it can easily hunt sea urchins and other small creatures.

The crested shark has a set of 300 sharp teeth, more than enough to grab any prey, preventing it from escaping.

Additionally, the crested shark’s mouth can also swell, enough to swallow prey half its size.

3. Sea worms or monsters?

This sea monster nicknamed Barry is actually a giant Bobbit worm. Each adult Bobbit worm is more than 10 feet (about 3 m) long.

Barry’s body is covered in thousands of bristles containing a poison that can permanently paralyze the nerves of anyone who touches it.

Barry often burrows deep into the sand on the ocean floor or hides in reef crevices. When ambushing the bait, only 1/10 of the body rises to the surface of the sand.

Along with that, their mouths are always open to welcome unfortunate prey that swims by. When the antennae detect prey, it immediately pounces, tearing apart even though the prey is many times larger than it.

4. The creature that makes you “dumb”: does the Lochness monster appear?

If you just look at it, many people are sure, this must be the mysterious creature in Lochness that we have been looking for for so long.

The food of this marine eel includes crabs, shrimp, fish or even squid and octopus.

In addition to the sharp outer teeth, they also hide another set of teeth in the pharynx position. When preparing to eat prey, these special teeth are raised toward the mouth, along with the outer teeth to help digest the food easily. This is known to be the only animal equipped with this special organ.
