Suctioning teeth
This photo will keep you awake at night if you are afraid of aliens. Even though they don’t appear to be so, squids can be quite deadly. They dwell in the deep sea and have a strange suction mouth full of sharp teeth that suggests they’ll eat whatever comes their way. You won’t believe what those teeth can do.
The skin and surface of other sea creatures and plants may be scraped with its teeth by this species. It has an elongated, jellyfish-like form, although it is not as dangerous as eels. These tiny mouths act as a plunger, ensuring that any food they suction up cannot slip away once captured.
