5 scariest creatures in the deep ocean

The scariest day of the year is just around the corner, so we thought we’d celebrate by paying homage to the most terrifying monsters in the deep blue sea. Okay, they’re not technically monsters, but you wouldn’t want to meet one on a swim.

Luckily, most of these scary sea creatures live in the deepest parts of the ocean, so you’re unlikely to meet one face to face.

  1. Giant squid

Giant squids were originally thought to be mythical creatures, until 2006, when Japanese scientists managed to identify and catch one. As the name suggests, giant squids are, well, really big. They’re also the largest invertebrates on the planet, weighing up to 900 kilograms and measuring as long as 18-metres.

These infamously shy creatures are unlikely to be a threat to humans, since they mainly feed on shrimp, fish, other squid. According to some reports they also have a penchant for small whales.

  1. Frilled sharks

If you haven’t already noticed, some of the strangest and scariest looking sea creatures live in the very deepest part of the ocean. One such creature is the frilled shark. This prehistoric creature has 3-pointed needle sharp teeth, and is considered to be a formidable hunter.

But don’t worry; the frilled shark is harmless to humans, so if you’re ever in the deep depths of the ocean you have one less thing to worry about.

  1. Pacific viperfish

The pacific viperfish is yet another deep-sea creature found at least 4,500 feet beneath the surface of the ocean. The fish hunts by attracting its prey with a glowing light (bioluminescent photophores), which emits from the creature’s belly. This light is made all the more alluring in the pitch-blackness of the deep ocean.

The viperfish’s fangs are so long it cannot actually close its mouth. This is perhaps what makes the creature look so scary and strange.

  1. The megamouth shark

Despite being a whopping 5.5 metres in length, the megamouth shark was only discovered in 1976. Since then, just 55 have actually been seen, which makes us wonder what else could be living in the deepest parts of the ocean.

Like the pacific viperfish, megamouth attracts its prey (plankton) with a glowing light. In this case, however, the light comes from the shark’s giant mouth.

  1. Blobfish

Okay, this one isn’t really that scary, but it was voted the ugliest animal in the world at one point. As you can imagine, it’s pretty weird looking. These guys live off the coast of Australia and New Zealand at depths of up to 1,200 metres.

The blobfish’s gelatinous flesh is less dense than water, but its reduced muscle mass isn’t a real disadvantage, since it typically eats crustaceans and other matter floating in the deep ocean.
