Suctioning teeth
If you are scared of aliens, this image will keep you awake at night. Squids can be very dangerous, even if they don’t look like it. They live in the deep ocean and their strange suction mouth full of sharp teeth gives us the impression that they will eat anything in its path. You won’t believe what those teeth can do.
This type of squid can use its teeth to scrape the skin and surface of other sea creatures and plants. Its elongated, gelatinous shape resembles that of eels, but is not as dangerous. In addition to their horribly terrifying teeth, these small mouths work as a plunger so their food cannot escape once suctioned up.
