I'm confused about tarantulas drinking from substrate

One of the reasons sponges are bad for tarantulas is that they can't drink from them. However, I've seen it said on AB that they can drink from moist sub. :confused: I am confused by this apparent contradiction.

(I am 100% for water dishes and against sponges etc. in them)

Sponges are bad because they’re a breeding area for bacteria and other microorganisms, where as substrate isn’t

Edit: I stand very corrected, disregard this post lol

That's a joke, right? Substrate is made to breed all kinds of microorganisms! I mean, any kind of healthy substrate should be full of them! Everyone who rated that post 'agree' hasn't really thought about it...

@MintyWood826 - I actually think that's an extremely good question, especially since I can't come up with a good answer on top of my head :rofl:

To the best of my knowledge this 'tarantulas drink from substrate' theory has never really been proven, though... I'm not saying it isn't true, I'm just saying I haven't seen irrefutable proof that they even do that.

My understanding is that it's not that they 100% can't drink from sponges, it's just extremely difficult. I would apply the same logic to drinking from the substrate, but it might be a bit easier to drink from the substrate since, when wet, that just becomes soggy particles whereas the sponge remains a solid object

It has been proven it to at least myself with my own collection. :p It surprises me you haven't seen at least one tarantula drink from the substrate in your own collection. There is nothing special about it. When an area of the substrate is soaked, like when one overfills the water cup/ dish, the tarantula spreads it chelicerae and pedipalps and presses itself onto the substrate instead of over the source of open water. In fact, in my experience, when given a choice tarantulas prefer to drink from the soil instead of the water cups I provide. The only reason I can ascertain is that it is easier for them. The amount of water a tarantula can get from the substrate depends on what type of substrate is used though. Coco fiber soaks up water like a, wait for it, sponge (!) and my tarantulas stay in the drinking position for longer than with topsoil which takes longer to absorb water poured onto it.

I have raised two Theraphosa blondi boys to maturity with no water cups/ dishes and in the process of raising two Theraphosa apophysis without them. In addition to those species have 5 other individuals of three different species being raised without any other source of water other than what I pour onto their substrate.

It is about time to re-soak the substrate for my two Theraphosa apophysis so I will be sure to make an attempt to get some pictures of them drinking from their substrate if they do so. I want you to see some kind of proof and not just take my word for it.

I actually have seen my G. pulchra drink from the substrate! If I ever see it happen again, I’ll have to take some photos.

Guess I didn’t really think about it either and just jumped to what first came to mind lol Makes a lot more sense when I actually think about it

I never understood where the sponge thing even came from... whose idea was that?! Lol.

I have never seen my Ts drink from moist sub, but I have seen them drink from the sides of enclosures when I mist (*gasp!* Yes, I said "mist"). When I put water onto sub, I make a puddle. Since I use topsoil, this is easily done. I guess I figure if they are thirsty, they can drink from the puddle before it absorbs?

Back in the dark ages before the interwebz, wet cotton balls in the water dish was all the rage!

I’m pretty sure I was told by pet shop employees that tarantulas couldn’t drink from a water dish without them.

And the 30 page pamphlet that covered scorpions, snakes and tarantulas was no help... anybody still got a copy of that?

Just petstores trying to find a way to be lazy and not give them clean water . Wonder how many of there inverts get eaten by the hordes of crickets jumping around inside cages.:banghead:

I *always* see people posting about the risks, but I have never actually heard of anyone's T being eaten by feeders...

Go figure I can't find it now, but there's a video on YouTube of a woman's sling (I believe it was a G. pulchra) that got killed by a superworm or mealworm that escaped getting eaten, burrowed, and reached adulthood. It does happen

I saw that one too. It's a real thing. Only a few of the sling's legs were left.

That's one of the videos I thought of too! Poor baby G. pulchra. Here:

Oh, I wasn't meaning that it doesn't happen... just that I had never actually read any accounts of it/seen photos of it myself.

So in these two cases, it wasn't the feeders in their feeder form, but escaped feeders that pupated. Darkling beetles are voracious predators... I feed mine roaches, so I can absolutely imagine they would target a vulnerable T.

Well, not necessarily "escaped," they were put in the enclosures during feeding and their owners didn't take them out when they weren't eaten.

One time, I dropped a superworm ("feeder form" not beetle) on my avicularia's web and it bit her, causing her to bleed a lot, but thankfully only on the leg. That was before I learned about crushing heads. The crushing-head method is pretty popular not just so they don't burrow but also so they don't bite, I believe.

And - same spider - I dropped a cricket on the bottom to let her hunt, and it NOTICED my avic on the wall, and kept JUMPING at her over and over, forcing her into a tiny stress ball. Never seen anything like it! Not saying you don't think they do, just wanted to add that I've personally seen "feeder forms" still attack, even when the tarantula isn't molting, so I'm sure it would've been worse if she was :(

Sorry, by "escaped" I meant "escaped being eaten" by the tarantula.

I have watched feeder worms try to bite at Ts if their heads aren't crushed, so that doesn't come as a surprise!

Crickets are just about the worst feeder ever, in my opinion.
