Costal Grooves – Grooves and on the flanks and dorsum of some salamanders which increase the surface area of the skin for water absorption and provide cutaneous channels which allow water to move up to the dorsum by capillary action.

Paratoid Glands - Permanent glandular structures found behind the heads of some salamandrids. These glands contain high levels of toxins which are secreted or in some cases sprayed at a predator.

Nasolabial grooves - Grooves found on the face of plethodontids that run from the nose to the mouth. During the breeding season they become elongated and a protuberance grows where the groove meets the lip. Thought to aid male salamanders to “smell” females in the area and avoid other males.

If no one has a picture of a nasolabial groove to add, Cameron has a really nice one I bed he'd let us use to illustrate it. I"ll email him.

Naslolabial groove:


did we do Mental Gland? Because Cameron also said we could use this picture:
(mental gland) moved to other thread

Yes, I did mental gland in this thread.

A few more, some of which are repeats. I think it's unwise (and difficult) to try to define every possible structure.

Laterally Compressed – an anatomical description of something compacted from the sides. Usually used to describe the fin like tail shape of aquatic and semi-aquatic caudata.

Dorsolateral – relating to structures or markings that run along the sides of the back. i.e. dorsolateral warts.

Dorsal – relating to structures or markings of the back i.e. dorsal line or fin

Caudal – relating to structures or markings of the tail i.e. caudal fin

Vertebral - relating to structures or markings that run along the spine i.e. vertebral ridge.

Nice photo!

thanks, I looked in the titles and didn't see it and I forgot. I moved the picture of the mental gland to that thread since it wasn't closed yet. How could I have forgotten those awesome papillae.
The pic above makes me think he's squeezing it and that's what makes the little prongs stick out (like popping a corn snake), because the little eyes look like they're bugging out too.
And what's the opposite of laterally compressed? When you step on something? Squished.

I think it's medially compressed, but I'm not sure. Squished is better :D.

Squished - relating to body shape after a sudden medially compression. See [stepped on newt].

Whenever I see something described as "squished" its referred to as dorsolaterally compressed. Sudden dorsolateral compression is an excellent new phrase for squished right up there with percussive maintenance.

How's this for a picture of laterally compressed?

Dorsolaterally or medially compressed I'm not furnishing.

I LOVE percussive maintenance. I used it on my computer just this morning.

Dawn, I don't think your critters can count for compressed in ANY direction.

Here's a toad that suffered a sudden dorsolateral compression. It wasn't me by the way... I wouldn't be that clumsy :D. Apologies to the squeamish.

Dorsolateral means from the back to the side. Would dorsoventral (from the back to the front) not be better for this purpose? We use that term as a non official descriptor for certain industrial and motor vehicle accidents, ie. the patient is DV Compromised.

I discussed this with my boyfriend (marine biologist), and he pointed out that flounders are described as "laterally" or "dorsolaterally" compressed, although personally he preferred dorsoventrally. Maybe it has to do with in what specific direction the compression occurred, or just what rolls more trippingly off the tongue (that, by the way, was said tongue-in-cheek).
Gee, maybe we could have a poll about it. :dizzy:

I have no dog in this fight so I will defer to the decision of the council.

I have no dog either and am going off the same info Dawn's boyfriend has (flounder, scorpionfish, etc being Dorsolaterally compressed.)

But, Dorsoventrally compromised is absolutely hilarious!

Thanks. Years in Healthcare will definately warp all but the most closed minds. The more acute the patients the bigger the warp.

The stories would shock most people.

Moved to the completed section using Mark's definitions (except for Squished?:confused: :happy:). Nasolabial grooves, parotoid glands, dorsal and caudal are defined elsewhere in the glossary.

Costal Grooves: Grooves and on the flanks and dorsum of some salamanders which increase the surface area of the skin for water absorption and provide cutaneous channels which allow water to move up to the dorsum by capillary action.

Laterally Compressed: An anatomical description of something compacted from the sides. Usually used to describe the fin like tail shape of aquatic and semi-aquatic caudata.

Dorsolateral: Relating to structures or markings that run along the sides of the back i.e., dorsolateral warts.

Vertebral: Relating to structures or markings that run along the spine i.e., vertebral ridge.

    Hi Lilith, you can check the medications page for a list of axolotl safe treatments. Although if the infection is mild, I would stick with fridge and salt baths!

  • faebugz:
    I believe the fridge gets to about 54°, so if you can replicate that in the tank, it might be okay. I personally would fridge just to make catching them easier, and if the infection is something in the water column at all, it will hopefully die out while they're AWOL (I'm thinking like ich for fish, not sure if axies have an equivalent)

    My three inch axolotl was having trouble pooping up to a few days ago. I wasn't feeding her as often because I was scared I would just add to her constipation. I fridged her until she pooped (twice), and then began to feed her around 6 bloodworms every other day. she's been pooping everyday now, but she's at that age where you can see through her stomach and I always see poop ready to come out but has not yet passed. I don't think she's constipated anymore, but I'm not sure and i don't want to over or underfeed her... any advice?

    Its probably not pooping because its hardly beign fed, it pooped in the fridge because the lower temp caused it to purge itself. If it stays constipated you can pm me

    Hi guys. Quick question. I have newly morphed eastern newt efts. They lost their gills but they still prefer the water. I have coconut fiber, moss, hidey holes and some food in the temporary habitat for them (waiting for the other newts to morph as well). But they still run back to the water. Is it the wrong substrate? Do they prefer something other than coconut fiber? I've been doing everything else properly (According to my research) but just wondering why they haven't ventured up. Have any ideas?

    My guess is they simply have no reason to leave. Do they still get enough food in the water? Maybe humidity is too low?

    I spray mist the place every day. And I do still feed him. One of them has finally come out. But now I have another problem. They don't look like eastern newts! I am posting pictures on a thread I've started. If you can, take a look for me and see. :)
