The Truth About the Sea Monster in ‘Below’ Is Far Stranger Than You Think

Netflix’s Newfoundland creature feature ‘Below‘ dropped all six episodes globally on October 8, and the first question on everyone’s lips is what the creature actually is. Outlets pitched the series as a blend of ‘Jaws’ and supernatural horror set in an isolated fishing community, so viewers walked in expecting a straightforward beast on the loose.

The answer turns out to be much more interesting than a mindless man-eater. The creature in ‘Below’ is a real puzzle for the people of Snook’s Arm, and the show spends most of its runtime peeling back what it is and why it keeps coming for them.

What Is the Creature in ‘Below’ Exactly?

Netflix’s own Tudum describes the creature as a highly intelligent deep water cephalopod. Reviewers have also pointed to a giant squid lurking in the waters of the tight knit coastal town, which gives the series a more grounded feel than its trailers suggested.

That grounding is deliberate. The drama favours a scientific footing over cosmic horror, and the creature carries none of the godlike traits of a Cthulhu or a Dagon. It is framed as an unrecognisable species of squid rather than something otherworldly.

The mystery only deepens once the characters start digging. Marine biologist Fonda Howander explains that the animal is intelligent, unlike anything on the taxonomic record, and female, which sets up the biggest shift in how the audience is asked to see her.

Meet Mudder the Giant Squid and Her Strange Influence

The townsfolk have a name for the beast. One character cryptically refers to the sea creature as Mudder and hints at a pact struck with her. That detail adds a layer of local folklore on top of the marine biology.

Mudder is also no ordinary predator when it comes to what she does to people. As the attacks begin, townsfolk experience violent symptoms including an unquenchable thirst and a terrifying urge to plunge into the ocean. The creature pollutes local drinking water with a hallucinogenic bacteria that triggers illness and violent outbursts.

Wade, played by Charlie Heaton, gets the worst of it. After getting too close to the creature he develops a large circular welt on his back, which Fonda identifies as the scarring sperm whales get from fighting giant squid. It is a creepy visual that ties the supernatural symptoms back to real ocean lore.

The Nest Twist and What the Icebergs Mean

Here is where ‘Below’ pulls its biggest switch. The creature is a mother, and the iceberg looming in the harbor is her nest. That discovery reframes her violent territorial behavior, since she is preparing to hatch a clutch of eggs.

Suddenly the monster is not the villain at all. One summary of the finale puts it simply, saying she is not a monster but a mother in crisis. Calvin, who spent much of his life consumed by fear and a need for vengeance, has to rethink everything he believed about her.

The finale also asks who the real threat is. The monster the show spent five episodes running from turns out to be a refugee, while the people it kept calling saviors turn out to be the danger. Calvin ultimately understands her purpose and saves her from being attacked.

There is a lingering question too. Calvin and Wade discover many more massive icebergs near the end, suggesting there may be other giant cephalopods out there. That leaves the door wide open for the story to continue.

Could the Giant Sea Creature in ‘Below’ Really Exist?

Short answer, not quite like this. Mudder is a fictional monster inspired by the real world of giant squid and other cephalopods. Real giant squid are not known to behave anything like the monster portrayed in the series.

Scientists have also poked at the show’s logic. One expert noted that giant squid lack the skeletal strength to do any harm to something above water. The level of intelligence the squid displays in the series is also described as unrealistic.

Still, the science gives the story its spine. The show combines marine biology with a tale of family, community and environmental change. Climate change and the loss of habitat and food in the deep sea are what push the cephalopod toward the Snooks Arm harbor, which makes the horror feel uncomfortably plausible.

So the creature in ‘Below’ is a grieving, protective giant squid pushed to the surface by a changing ocean, and the real monsters may be the people exploiting her. If you watched Calvin choose to protect Mudder instead of destroying her, do you think the Penneys made the right call, and would you trust those mysterious icebergs to stay quiet in a second season?
