So, a typical snail moves at around 0.0048 km/h, and are around 1 cm tall. The snail in the image appears to be more than 3-4 stories tall, let's say 15 m. If the speed scales linearly with size, this snail could move at around 7.2 km/h.

So yeah, a very brisk walk for your life should just about keep you out of reach if you're in decent shape.

It was an asymptomatic smash!

Or even asymptotic.

Your linked source doesn't appear to list that number (It lists 8 cm a minute).

Perhaps you (or a large language model, if you're using one) has it mixed up with this:

"Snails have been measured at speeds of 0.048 kilometres per hour."

From this source.

Also, 1 cm tall would be a very small snail... Approximately the size of your smallest fingernail.

8 cm/min * 60 min/h * 1e-5 km/cm = 0.0048 km/h

If I'm not completely mistaken.

I'll admit that the "1 cm tall" is guesstimated based on my memory of the snails in my garden.

The linked source also mentions that some snails can be up to ten times as fast as the typical 8 cm/min (0.0048 km/h), but those appear to be maritime snails, while the snail in the image seems to be terrestrial.

Oh yeah you're right 👍

The source I found appears to list the wrong figure.

Yea, yea ... you have the math for a snail. Impressive. Could a bird carry it and drop it on people? How big would it have to be? Could you outrun it? What is the airspeed of an unladen swallow?

Saunter at your own peril.

I was hoping someone had calculated how quickly a snail that size would move, and you did not disappoint!

the problem is snails harbor tons of parasites, the slime it leaves will just infect everyone in its wake.

[–] beastlykings@sh.itjust.works 2 points 1 week ago

I was thinking this might be the case, but didn't want to do the math. Thank you.

Unless it's a carnivorous snail
