8. Bioluminescent Octopus
This impressive feat of nature is also known as the Glowing Sucker Octopus, because, you guessed it, it glows. They are found off the coast of the United States, as well as in the sea around the British Isles at extreme depths.
It is thought that they dwell in depths of around 4900 feet and 8200 feet. For this reason, as with most creatures that live in depths such as these, very little is known about them.
Not many studies have been undertaken on the species and so it is difficult to ascertain much information about them. Their mantle (this is their 'body') is thought to be around 2-4 inches long, but their arms (or tentacles) range up to around 14 inches.
That being said, their tentacles are thought to all be of unequal lengths.
Not much is known about its feeding habits, but it is thought that they evolved to become bioluminescent as a means of scaring off possible predators. Their shape makes them look a little like an umbrella, and the bioluminescent features are around the ends of the tentacles. They are certainly an impressive species that we hope to learn much more about in the near future.
9. Vampire Squid
The Latin name of this species is Vampyroteuthis infernalis which translates roughly to 'vampire squid from Hell'.
As if that wasn't enough to terrify you for life, the appearance of the squid itself looks like something from a horror movie. That being said, it is still no less than an awe-inspiring creature.
Just like the octopus we just discussed, this squid has adapted and evolved to become bioluminescent in order to survive in the depths of the sea in which it resides.
The vampire squid dwells at depths of 2000 feet to 3000 feet, with some even believing it could be more than this.
Despite its name and similarities, it is neither a squid nor an octopus but instead has its own grouping.
Living at depths like this, they have had to adapt to survive with very little oxygen and in extreme darkness. This alone makes finding prey hard. However, these squids also have no feeding tentacles, unlike other squids and octopi.
For this reason, they have two filaments covered with fine hairs that allow them to find prey to feed on. In terms of feeding, the prey they capture is not what you may think, given their name.
They have no real taste for blood but instead, eat far smaller organisms such as zooplankton. They do, however, have their own predators, having been found in the stomachs of whales, big deepwater fish, and even sea lions who dive deep.
