Have you ever had that moment when you’re at the beach, you’re waist-high in the ocean, and you think you feel something brush your leg? Ever been on a boat or a ship miles into the ocean, and you think you see a shadowy figure gliding through the water? Is that just your imagination, or is there a creature lurking under the surface? Yes. The answer is always Yes.

Hopefully, you’ve never experienced a terror like the following films that are currently streaming. From the shores of the ocean to miles and miles below the surface, these films showcase terrifying underwater situations and ungodly sea creatures.


Sweetheart (2019)

Streaming on Netflix

Jenn has washed ashore a small tropical island and it doesn’t take her long to realize she’s completely alone. She must spend her days not only surviving the elements, but must also fend off the malevolent force that comes out each night.”

Having the boat that you’re on go down, and waking up alone on a deserted island is pretty bad. You have to fend for yourself while you hope that help comes along. Instead, what comes along is a huge creature that arrives from a black hole on the floor of the ocean, and wants to drag you back down that hole for supper. Kiersey Clemons’ Jenn takes charge of the situation and the entire movie as she fights the elements and fights the creature.


Aurora (2018)

Streaming on Netflix

The passenger ship Aurora mysteriously collides into the rocky sea threatening an entire island. A young woman and her sister must both survive by finding the missing dead for a bounty.”

The titular ship, the Aurora, is shipwrecked right offshore of the seaside inn owned by two sisters. It’s torn the community and the inn apart, but the eldest sister decides to stick around to account for any bodies that wash up on shore. They say the dead will not rest until all of their business is resolved, and there’s a secret among those who were on board the Aurora that hasn’t been resolved. This results in waterlogged ghosts and time travel to the moment of the shipwreck as the dead scream out for their help.


The Reef (2010)

Streaming on Shudder, Prime, Tubi

A great white shark hunts the crew of a capsized sailboat along the Great Barrier Reef.”

Based on actual events that happened to a group of people in the 80s, The Reef is as simple as a shark film can be, yet it has scenes that emit a sense of anxiety and urgency. The sharks stay mostly unseen. It’s the situations that the characters are placed in that bring about the tension. When your only chance of survival is a swim of 10 miles or so while a hungry shark is stalking you, there’s no time for a chill. It’s swim or (er, and) die for these people.


Harbinger Down (2015)

Streaming on Prime, Tubi, Pluto

While studying the effects of global warming on a pod of whales, grad students on a crabbing vessel and its crew uncover a frozen Soviet space shuttle and unintentionally release a monstrous organism from it.”

Mix Alien with The Thing, place it within a crabbing vessel that’s off the coast of Alaska, and you get Harbinger Down. While it’s no classic like the inspirations that it drew from, the film is a fun 90 minutes. It boasts a gnarly creature and messy gore done with solely practical effects.


Sector 7 (2011)

Streaming on Tubi

Something awaits 2,500 meters under the deep sea off the southern tip of Jeju Island…Directed by Kim Ji-hoon and produced by JK Youn, the sci-fi action thriller Sector 7 revolves around an oil rig crew forced to battle a deadly creature at sea.”

Sector 7’s oil rig crew are a tough group of people as they take many a beating whilst giving quite a beating to the behemoth that arrives from the bottom of the ocean to wreck havoc. Leave your troubles at the start of the film as it takes you on a nonstop thrill ride full of creature mayhem, motorcycle races, quirky comedy, and a badass heroine who is just as unstoppable as the creature.


47 Meters Down (2017)

47 meters down uncaged 2019

Streaming on Netflix

Two sisters vacationing in Mexico are trapped in a shark cage at the bottom of the ocean. With less than an hour of oxygen left and great white sharks circling nearby, they must fight to survive.”

Whew, let’s talk about anxiety. The sisters are stuck at the bottom of the ocean in a cage. They’re running out of oxygen. Sharks are either circling the cage or trying their best to get in. 47 Meters Down gives anxiety in droves. It’s not just about the sharks and the anxiety. It’s also about what one would do to protect someone they love, and that is where the film truly rises. But I mean, sharks.


47 Meters Down: Uncaged (2019)

Streaming on Prime

Four teen girls diving in a ruined underwater city quickly learn they’ve entered the territory of the deadliest shark species in the claustrophobic labyrinth of submerged caves. “

47 Meters Down’s director, Joannes Roberts, returned to direct the sequel. For 47 Meters Down: Uncaged, he gave us an entirely different movie. He switched out a shark cage for an entire system of underwater caves, introduced a kind of shark not seen before on screen, and upped the ante on the action. The girls get themselves into some pretty crazy situations and are always half a step ahead of or behind the sharks stalking them. The finale of the film is a shark movie highlight.


The Chamber (2016)

Streaming on Shudder, Tubi, IMDbTV

A three-man Special Ops team on a secret recovery mission and a civilian pilot become trapped underwater in a small claustrophobic submersible craft off the coast of North Korea.”

It’s not always a creature under the sea that is the antagonist. Sometimes, it’s humanity. The Chamber gives this perspective with 4 people who are stuck within a 2 person sub that has wrecked on the ocean floor. Granted, the three Special Ops members have the majority over the unsuspecting pilot. Or do they? Loyalty is questioned, misplaced, and replaced as the situation gets worse within The Chamber.


Leviathan (1989)

Streaming on Prime, Tubi, Pluto

An American deep-sea mining colony stumbles upon a sunken Soviet vessel hiding a horrific secret.”

Leviathan’s sea nemesis is downright nasty. It’s a parasite that uses its host to generate itself, and does so in many beautiful (ie nasty) ways. The mining crew was out for silver, but what they got instead was a body horror nightmare. Leviathan gets extra points for its fun cast (Daniel Stern, Ernie Hudson, Meg Foster, Hector Elizondo), and for the viciousness of the parasitic sea creature.


Deepstar Six (1989)

Streaming on Prime

At the bottom of the ocean, the DeepStar Six has just discovered a new and deadly alien menace.”

Deep Star Six plays out almost like a slasher, I thought as I was watching it. Color me surprised when I saw that no other but Sean S. Cunningham (Friday the 13th) was the director. Perhaps there’s no correlation, but the thought manifested due to the stalk and kill method of the creature from the sky turned creature of the sea. That creature means business.


Parasites, ghosts, aliens, and humans are the cause of these ten aquatic horrors. Which of those would you rather not face while being surrounded by tons and tons of water?
