Is the Leviathan Real? How Warming Oceans Reveal the Truth

Fisherman catches a 2023 oarfish—is this the leviathan real?

Could the Leviathan be real? Discover how warming oceans are bringing deep-sea creatures like oarfish to the surface—a perfect blend of myth and science!

Friends, imagine a scene: A fisherman in Japan casts his net into the ocean and when he pulls up, a 6-meter long oarfish emerges—glittering, absolutely ancient! What is this—is Leviathan real or not? These days deep sea creatures are frequently seen on the surface—50 oarfish together in Japan in 2023, in the waters of California in 2024, and up to Mexico in February 2025! Scientists say this is due to warming oceans, but there is a curious question in my heart: is this just science or is there mythology also mixed in it? In this article, we will explore both—the leviathan myth and the changing form of the ocean. I myself saw this in the news and thought, Ohh, this is a blockbuster movie! Are you excited? Let's dive into the mystery of this deep sea life!

The Leviathan Legend—Myth or Reality? 

What is Leviathan in old stories?

Ancient tales of leviathan myth

—from Bible to Japan!

Friend, there is mention of a big sea monster in the Bible—is Leviathan real or not? This question is old. It was described as a giant serpent, the king of the sea. Not only in the Bible, such sea monsters are also mentioned in Hebrew, Mesopotamian, and Greek stories. People say that it used to hide under the water and when it came to the surface, people used to get scared. It is a drama, right?

Even today in Japan people believe that events like sea monster sightings in 2025 are big signs. There were oarfish sightings before the 2011 tsunami, and in 2023 50 oarfish were seen together! A friend said, Bro, this is the return of the Leviathan myth! Just thinking about it gives me goosebumps. Old people probably turned them into myths, but today science is shedding light on it. By the way, if you want to understand these old stories further, then there is a good video on the 2023 oarfish sightings on Newsweek —don’t forget to check it!

Oarfish: Is it the real Leviathan?

Leviathan real or myth? Warming oceans reveal all!

Now let's come to the real thing—oarfish sightings. This fish is 6-10 meters long, with a silver body, and so rare that seeing it is a dream. In 2023, 50 oarfish were caught in Japan, 3 times in California in 2024, and in 2025 a live leviathan oarfish was caught in Mexico! It looks exactly like the old people used to describe it—long, shiny, and mysterious.
 
I saw a video and thought,  This is a special effect of nature!  Scientists say that this could be evidence of real leviathan which inspires the leviathan myth. In Japan, it is called Doomsday fish—what do you think, is this the leviathan in real life? If you want to know about more Strange Sea Creatures, then read our post—you will enjoy it!

Why are deep-sea creatures coming to the surface? 

How are warming oceans changing water?

Look friends, warming oceans is no joke. Scientists say that since 2000, ocean temperature has risen by 0.15°C—it seems a little, but it is a big shock for deep sea life! As the water gets warmer, oxygen levels are decreasing, and deep sea creatures are coming to the surface. An example: the Giant Phantom Jellyfish, which lives 1 km below, was seen on the surface in 2024!

I had studied about the ocean in school—it was not serious then. But today the effects of warming oceans are visible everywhere—oarfish are linked to climate change. The Black Sea Devil Anglerfish is also coming to the surface—it is that creepy fish seen in horror movies! Mexican fishermen said in 2025, This never used to come before!  All of this is proof of how warming oceans affect deep sea life. If you want to understand the science behind this, there is a detailed article on National Geographic—you will understand how this is happening after reading it.

Climate Change—The Hidden Danger

What is the effect of climate change in the ocean? Ocean warming impact is creating heatwaves and dead zones—oxygen is depleted, so deep sea creature migration is increasing. In 2025, there were talks of oarfish sightings and global warming up to Mexico—a fisherman said, This is the ocean's SOS!

Stats say that 70% of deep sea climate effects depend on oxygen—if it decreases, then either we will prosper or we will die. It's dramatic, isn't it—are we doing all this with our carbon? Last year the water felt warm on the beach—this small hint tells a big truth! And if you want to do a deep dive in this then read our post Oarfish Sightings And Global Warming —everything will be connected.

Science vs. Myth—What is the connection? 

Is Leviathan a misunderstood creature?

So is the Leviathan a real sea creature? Leviathan science says that Leviathan could be the base of old oarfish myths. People in Japan believe that oarfish sightings are a sign of disaster—this was repeated in 2011 and 2023. Bro said, This is the code of nature which we are not able to understand!

leviathan oarfish—real or myth?

Look at Leviathan myth vs scientific facts—the shape and rarity of the oarfish must have seemed like a monster to old people. This curious connection touches the heart—are these deep sea creatures climate change proof too? If you want to understand this combination of science and myth, then do some more research – you will enjoy it!

Big Picture—Ocean and Us

Friends, ocean climate shifts do not just touch fish – they also touch us. The deep sea stores carbon, and if this is disturbed, the ocean climate change will be worse. Think dramatically: are we awakening legend and ocean changes by pushing sea life up from warming oceans? I saw it in the documentary – we are hitting our own feet with an axe! If you want to do something for this, then go to Ocean Conservancy  and read about ocean protection – it is very inspiring.

So friends, whether leviathan is real or not, warming oceans is true—and it's bringing the secrets of deep sea creatures to the surface. Oarfish, jellyfish, anglerfish—we want to say something. The combination of Leviathan science and myth is interesting, but also scary. What do you think—are sea monsters real or a warning? Say it in the comments, share your thoughts, and share this with friends! The future of the ocean is in our hands—let's start a conversation, let's bring some change!
