Sleeping Haplotrema - update

The dormant Haplotrema concavum that I found on 20 December 2007 (73 days ago) was still hibernating this afternoon. The previous posts about this particular snail are here and here.


Tomorrow and Tuesday are predicted to be unusually warm. If the warming trend continues and if the snail is still there next weekend, I may attempt to revive it then.

What would the snail's heart rate be during hibernation?

I have this mental image of you performing mini-CPR on that snail to revive it (poke..poke..poke..huff..huff..).

How do I make this image go away?


coyote: Metabolism slows down during dormancy, so I would think that heart rate would also be slower than it is in an active snail. But I don't know if anyone has ever measured it. It wouldn't be too difficult to do it, because the heart is usually visible thru the shell if the shell is translucent.

Zo: You can't make it go away until you buy me a beer the next time we get together.

I had the same question as o.b.! I imagined you just knocked on the shell! ;)

I thoroughly enjoy your blog/site, especially the safari like field trips and small wonders like snails

I have two snails that I picked up in miami late last year that I could use some help in identifying: I believe that they are asian tramp snails, but they (either or both)could also be florida scrub snails.

The tend to hibernate if it gets cool or dry in my apartment and grow a small calcified cover, and i suspect that they would stay dormant if i didn't mist them from time to time when i clean their container.

Could I send you a photo (or a scan?) to aid in identifying them?
