Science Fiction

FOH there's no way a graboid is bigger than a sarlacc.

Edit:

OK with some web searchin', I got some rough guesses as to the size of each one (spoilers: OP's chart is so far off it's probably a troll):

• Graboid. They fit in a flatbed truck bed. The Tremors wiki puts them at 9m long and 2m wide, making them approximately 2 rhinos big.
• Beetlejuice sandworm. There's an amusing behind-the-scenes photo of the set construction for the sandworm scene, which has a model sandworm next to a model door, the door they step out of when they try to leave the house. The sandworm's visible body is perhaps 2x the height of the door, and most of it is underground. Figuring a 2m door height, we can estimate this guy is about 20m long. Not something you want to meet in the dark, but only about 4-8 rhinos big.
• Sarlacc. A real big boy, about 100m in length, unknown average diameter but the artists' depictions I've seen make it look like roughly 30-50m in circumference, or about 12-16m in diameter. Probably 400 rhinos big.
• Shai Hulud. One of these things eats an entire spice harvester in one bite. Basically doesn't even belong on this chart unless this is a log scale, these guys are 15-25 meters in diameter, big enough to eat the flatbed truck and the graboid without even noticing it swallowed them. Probably a mile or more in length. Given the current state of the rhino population, a Shai Hulud almost certainly outweighs all rhinos put together.

It should be noted that while the sarlacc's diameter seems to put it in punching range of the shai hulud, two things really set the Dune sandworms apart:

1. Basic biology math. The mass of the creature increases with the cube of the diameter, so a ~2x increase in diameter for the shai hulud translates into a mass ratio of 8x.
2. Length. Shai Hulud are much more wormlike than Sarlaccs. That means they're far, far longer relative to their diameter.

Put these together and you can be pretty sure that a sarlacc to a dune sandworm is like a puppy.

EDIT 2:

I am pleasantly surprised to learn that some species of rhino have many thousands of individuals. I believe they would, in fact, outweigh a single Shai-Hulud.

Everything about this is wrong.

• Graboids are the smallest, maxing out at 10 meters in length.
• The Sarlaac pit is just the mouth. The actual Sarlaac is 100 meters long
• The Beetlejuice Sandworm has a head slightly larger than an average door, so about 1 meter wide.
• Shai Hulud get up to 1000 meters in length (pre-Brian Herbert Lore) and around 40-50 meters wide.

Graboids are not that big, they can fit on a flat bed trailer.

Where is the Alaskan Bull Worm?

This is waaay off. Also missing the D&D purple worm...

The worm in beetlejuice is simply called a Sandworm

So, the sarlacc. The bits of it we see in the movies, are its mouth (the pit with the spiky stuff,) and its (apparently beaked) tongue.

The sarlacc is probably quite a bit larger. (Maybe not dune sand worm big.)

No alaskan bull worm?

Could add the Exogorth from The Empire Strikes Back. That thing was massive.

Where Krayt dragon?

I’m curious as to the comparison of the No Man’s Sky sandworm.

It’s a BEEEEG boi.

I think the Saturn Sand Worm was a good change to the original flying clocks in an empty void idea.

Must be a height chart...?
