Photos of 3 types of Ampullariidae: pomecea bridgesii/diffusa (male, ~6mos, light bodied wild), pomecea canaliculata (gender?, ~4mos, dark bodied) and marisa cornuarietis (female, ~8mos, both gold and striped).



pomecea bridgesii/diffusa




Note how the spire whorls are stacked neatly like a cake.




Note how the seams between the cake layers are smoothed over




----

pomecea canaliculata




Note how the "cake" has sunk in on itself



Note the cake's seams are more obvious and grooved.



This is from another cana I first used for the images then noticed his spire was weird, so I used another for the above image.

Great informational pictures Paula . Easy to understand, thanks a lot!

[rpilla001]

Who is the hitchhicker on the Marisa?

[Donya]

Am going to stickyfy this, hope you don't mind; there aren't many stickies in this part of the board. Some of these photos really exemplify the spire differences and would be good as reference in addition to the species pages of the site.

EDIT: how certain are you of the ID on the Viv? The sharp angles look an awful lot like the offspring from the Cipangopaludina japonica I used to keep.

[Pollux]

nicely done

[PaulaO]

The baby viv on the gold marisa is from the three I got from a plant/pond place here, locally.

Their offspring is quite different from the offspring of the vivs I got from Rainbow Snails a long time ago. For one, the juvies are brown and sharper, especially in a raised rim in the middle of each whorl.

I'll work on getting images of those next. None of the parents are alive, however. I do have photos of them all, though.

If anyone has any of the other species, I'd love to add in photos of those, taken from the same angle as the ones I have. That way we can compare then easily. Robert, some of your flapples, please?

Great job Paula

[rpilla001]

And where are the Flapples?

[PaulaO]

In YOUR tank. Waiting to be photographed by YOUR new camera.

So, like, where are the photos of the flapples??

[Lupin]

This is really a great help! Thanks, Paula.

Paula,

I would be very cautions when Identifying P. canaliculata. The shape of the spire and depth of the channel is nearly identical to the P. Insularum. I would suggest adding photos of egg clutches sizes, color, and shapes. This is the best way to distinguish between a P. canaliculata and a P. insularum. Even then it is still difficult without genetic testing.

P. Paludosa

P. Paludosa is native to Florida and the only natve apple snail to the United States.

Robert, I know I'm like a broken record, but you really need to be taking photos for National G or Ranger Rick or someone!

[Annie Anderson]

I'll second that PB--those pictures make me feel like I'm standing right there looking at the snails and eggs myself
