What species, externally, do not symmetric, or nearly so, left and right sides?

Asked by Halliburton_Shill (268points) April 8th, 2009

As inspired from this:

I’m not talking about tiny variations that would disappear as a result of environment adaptation. Consider birds, humans, and buttocks as examples of the symmetric. A fiddler crab as an example of non-symmetric.

Snakes, eels, rays, ameobas,
I don’t know?

Star fish and brittle stars.

(@Bargardbilla While your examples are elongate, they are still symmetric.)

My right foot is about an inch longer than my left, so…me.

When did “symmetric” become a verb? I turn my back for two seconds and look what happens?

tonedef's avatar

@syz, starfish do exhibit radial symmetry, but I guess that’s not the question.

Sponges, corals, oysters, and barnacles are ones I can think of.

@Poser Whoa! Freakshow! ~~~~~~ ;-)

Isn’t there a marsupial having a specialized finger on one hand to stick into burrows and holes for bugs?

syz's avatar

You’re thinking about the aye-aye, a lemur. But the finger is on both hands.

The wonky-eyed jewel squid (I am not kidding.)

Hermit crab.

There’s a bird with a beak thar curves to the left, so that i can pick out food from under boulders. I don’t know what it’s called, though.

I was going to comment on the off center-ness of human organs, but then I re-read your question.

some crustaceans have ONE GIANT CLAW. Freaks.

Humans are actually asymmetric. If you took a picture of yourself and tore it in half. Then duplicated one half and put it together to be one person you would actually look like a sibling of yourself rather than yourself.

crisw's avatar

You might be thinking of the wrybill.

tonedef's avatar

@crisw yay! That’s exactly the one.

What language is this?

fundevogel's avatar


also, sometimes antlers are asymmetrical.

YARNLADY's avatar

“do not symmetric” is not proper English. The word symmetric is not a verb. I believe the asker means “are not symmetrical”, or “do not grow in a symmetric manner”.

gailcalled's avatar

Note sixth answer from top, please.

YARNLADY's avatar

@gailcalled IMO not specific enough

crisw's avatar


I think he’s just missing the word “have” before “symmetric.” Surprised the mods haven’t fixed it yet.

YARNLADY's avatar

@crisw Oh, yes, that would make sense.

gailcalled's avatar

@YARNLADY; We both omitted to mention also the awkward final phrases: “or nearly so, left and right sides”? And that “externally,” plopped where it was. I think everyone understood what he was asking. It’s what I call a “mangle-wurtzel” question.

Simple, trees and virtually all plants.

flat fish….but i think perhaps they do start off symetrical and then their face kinda goes off to one side….how upsetting would that be if you woke up one day and your face had decided to all go off to one side of your head!

What is that fish that has both his eyes on one side? Is that a flounder?
