The Grabblog

Graboids are extremely ancient (Precambrian) lifeforms. They date to a time when it was thought no vertebrate life existed on Earth.Rare throughout history, they were almost never captured in the fossil record. Kate White discovered the only known Graboid fossil. Rhonda LeBeck has now earned her Ph.D. and is the world's foremost authority on living Graboids. She sometimes returns to Perfection to study El Blanco.

The life cycle of the Graboids currently appears to be as follows:

A Graboid egg lays dormant for up to three centuries, or possibly even far longer.

A single Graboid worm hatches from each egg.

The newborn Graboid eats all manner of organic material and grows rapidly.

When the Graboid reaches maturity, it metamorphoses into approximately three to six bipedal Shriekers.

Shriekers reproduce hermaphroditically. Their ability to reproduce is limited only by their food supply. Their cycle of reproduction is very short, often being measured in hours.

Approximately 24 to 72 hours after spawning (during which, depending on food supply, an indeterminate number of parthenogenic reproductive cycles might have occurred) Shriekers metamorphose into AssBlasters. Each AssBlaster carries within its torso a single fertilized Graboid egg.

At some stage not yet observed or understood, an AssBlaster buries its Graboid egg in the Earth for gestation. It is unknown how long an AssBlaster can survive after relinquishing its Graboid egg.

Science now recognizes that there probably are eggs of this ancient but extremely rare lifeform buried all over the world, as evidenced by the Graboid appearances in Mexico and Argentina. Like the coelacanth, the animals simply went unrecorded throughout history.

Until now....
