Prehistoric Animals That We Are Glad Went Extinct

Hallucigenia

#13 Hallucigenia

From whatever we know about it, it is straight out of your worst nightmares. It wasn’t big and was only around 30 millimeters in length.

It is estimated that the sharp pincer-like mouth, lack of eyes, nose, and innumerable tentacles helped it suck water into its body.

Many scientists also believe that this prehistoric creature was a detritivore.

The mystery still remains. However, your imagination is enough to keep you up all night after one look at the Hallucigenia.
