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.
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.
