Weird behavior. T. Stirmi male

[MyTsKeeper]

My male T. Stirmi is wondering a lot and it seems a bit erratic. His abdomen has a clear liquid by the spinneretes and it’s collecting substrate as he moves around. I’m used to him being active at night. But it is currently 1:00 pm where I live and he’s been all over his enclosure sense I first checked him at about 8:00am which is usually around the time he begins to wind down. Not sure what’s going on here. Anyone experienced this before??

Can you post a picture of the full enclosure? Do you have cornstarch? I’d sounds like he may have an injury. When did he last molt?

He last molted before I got him. I’ve had him a month or so no molt yet

It’s not the fall distance, so that is good. Hemolymph is clearish and that is my assumption. If that dirt is stuck, leave it as it is it’s bandaid. If it comes off and starts leaking again, apply cornstarch to clot it. Just be careful not to get it on the anus or book lungs. I would lay off feeding and just provide clean water at all times as you don’t want a swelling abdomen to put more pressure on the injury.

A few possibilities:
Exploring the enclosure as you've only had it a month.

Looking for a hide or darkness; maybe throw a towel over the tank or something.

If it's a mature male it could be looking for a female; you'd have to check for palpal bulbs as this species doesn't have tibial hooks.

Sounds like a MM!

Look at picture 3. No emboli. I thought that, too, at first

Hopefully just "Settling In" / getting used to His Confines ...
more updates and pictures of this Beauty are more than welcome.
Best Regards,

Can you please elaborate this a bit?

What part

I dont think the missing hair is kicked UrS. It hurt itself on something. I don’t know how it was living before but it obviously has kicked a lot previously.

If you male has not hooked out yet (look at mature male photos), it could be getting there soon.

Wandering is normal in a new enclosure. But mature males do tons of wandering because they need to mate. Thats when they risk falling on stuff.

Maybe it explored and scraped itself on decor.

Some of my tarantulas have a tiny bit of fluid come out before they molt. The skin has a line and it looks like cracking. Thats not what yours looks like though. Doesnt mean its not nearing a molt.


At this point all you can do at this point is wait. And observe.

Try to figure out if its a mature male. Look at pedipalps and hooks on front legs.

He is definitely fat. So its not underweight.

Based on the screenshot, now I know why some people use the word “emboli” incorrectly. That has been bothering me for a while. Tom of “Tom’s Big Spiders”- who is regarded as a good source of info- doesn’t know his anatomy. The arrow is supposed to be pointing at the palpal bulb; the embolus (plural- emboli) isn’t visible in the graphic. Hopefully someone clued him in and he has a corrected image somewhere.

I am closely monitoring him. He is male sexually mature, I’m not sure. He is about 5 inches DLS. I think maybe my substrate is too dry causing it to stick to him. Also I’m wondering why is collected in that area on his abdomen. I will try for more pictures. I don’t like poking around for photos. Thank you all for amazing feedback.

to me, emboli, is a strange pointy drop shape, on the pedipalps. Its different depending on species.

Like this:



Do i understand it properly?

It is was it used to gather the “sperm” to be inserted into the female.

the previous image i used was in the first search results. I thought it would help OP where to look for signs of a mature male. I figured it was a good vulgarisation. So its wrong?

Yes, you understand it correctly. The embolus (plural "emboli") can be defined as the distal sclerite of the palpal bulb or male genital bulb. In more simple terms, it is the pointy bit that varies in length and shape at the front of the entire structure attached to the pedipalp (the cymbium [modified palpal tarsi] to be exact). It drives me crazy when someone says "look for the emboli" in response to how to tell a matured male tarantula from females or immatures. Sometimes you can see the embolus, but what people are really meaning is to look for the entire structure which is called the palpal bulb. It's kind of like someone not knowing that a finger is a separate structure, but attached to, a hand.

I understand perfectly. Thank you for bringing it up. Im pretty sure ive wrongly used the words in the past. Although i prefer to use Hooked out when refering to males.

i can see how it can irritate a person, especialy those who have a science background.

i will be careful in the futur, and make sure i use the right vocabulary.

thank you for pointing it out.

i dont think its mature yet. But its getting there. If its a male.

who confirmed this as a male?

Well the pet store I rescued it from said female. But I posted a thread a while back when I first got it. The nice amazing people on arachnoboards said he was male. Based on his underside. (Photos below) + an appreciation photo. I love this T and I just want the best care for it.
