Newly Discovered Snail "Breaks All the Shell Rules"

Any snail enthusiast knows that their favorite creatures' shells follow certain stead-fast rules: They are cone shaped, right handed, and spiral on a single axis logarithmically. Well, let me just tell you what a shock it was to the snail community when scientists recently discovered the Opisthostoma vermiculum in Malaysia. The snail version of James Dean, the Opisthostoma vermiculum's shell breaks all the rules and answers to no one. Do you think you're the boss of it? You're not.

What a Hell's Angel's shell would look like if he wore one...

Seen in the picture above the Opisthostoma vermiculum shell rotates on four different axises (I apologize if you just spit out your coffee on your computer screen). In order to do this, the snail must have twisted inside its shell as it was forming. The shell also ...

...coils, uncoils and recoils all around itself, detaching and reattaching the whole time. Needless to say, this has never been seen before.

"I thought it was one of mother nature's practical jokes," said Reuben Clements from the World Wide Fund for Nature in Selangor, Malaysia, in this article on Nope, he found a bunch more of the shells in a quarry, and confirmed this is one twisted f-ing snail...literally. Unfortunately, they have yet to find a living sample, so we're just going to have to hold our breath to find out what it's looks like. In the meantime, just try to forget everything you've ever known about the geometry of snail shells.

Sometimes we just need a little help to get by in life. A nudge, some encouragement or a simple pat on the back will suffice.

Time always marches forward, of course, but does evolution? It's certainly easy to impose a march of progress on the course of evolution. That's why the sequence of apes transforming into humans as they march from left to right is so universal. Of course, there are also pictures in which Homo…

I want a baby-snail for pet - I would name him Reuben and watch him touching himself/

That's remarkable. It's even more remarkable that all the shells they found seemed to display the four axes and the detached-attached coiling scheme, so it's not a case of a weird mutant or random coiling. Very cool!

It looks like this baby is zooming, ( OK, snail pace crawling, LOL), ahead of all the others. Cool PIC! Thanks!

In order to do this, the snail must have twisted inside its shell as it was forming.

So refreshing to find another organism in the universe that also wakes up with its socks on backward in the morning.

Oh now

You've made my morning.
