Shrieker's History

The Shrieker (also referred to as "Screechers" by Nancy Sterngood or "Squealers" by Mindy Sterngood and George Meadows) is a fictional species in the Tremors series of films. The Shrieker stage is the second life cycle stage of the creatures featured in the series; the Graboid being the first and the Ass Blaster being the next and final.

The Shrieker can be seen as a kind of pupa without the immobility, or a nymph even though a nymph would be the young beginning stages for animals (insects) with incomplete metamorphosis, the Shrieker being the middle "teen" stage. And the Graboid species clearly shows a complete metamorphosis. Shriekers are arguably the most dangerous form of Graboid, as they reproduce the fastest, can run on land or tunnel underground and have a voracious appetite, necessary for them to grow into Ass Blasters and lay Graboid eggs.
