News from the Spider House

WARNING: This post may contain spiders. Or at least pictures of them. Don’t click through if you don’t want to see them!

Remember when I said that 11 spiders was quite enough and that we’d probably be sticking with that for a while? It totally wasn’t true. We are now up to 14 and may be going to the spider shop tomorrow for numbers 15 and 16.

In my defence only one of the three new ones is mine, and look at it:

A black tarantula with a small orange heart-shaped patch on its abdomen. It's slightly smaller than the milk bottle top it's sitting next to.

It’s a spider with a heart on its bottom. Who could resist that?

That’s Thirteen, by the way; s/he is a Cyriocosmus sellatus (Peru Dwarf Tiger Rump), a dwarf tarantula, and that’s about as big as it’ll get. As for sex, all I know for sure is that it isn’t a mature male. I’m hoping it’s a girl, but we’ll see!

And here’s a bad picture of Basil, one of Mr Satu’s new ones, menacing a cricket:

A plastic deli cup, almost entirely filled with web; inside is a spider, about as big as the cup is tall, and a cricket sitting just under the edge of the cup.

Basil (the second of Mr Satu’s spiders to get an actual name) is a Chilobrachys fimbriatus, or Indian Violet tarantula.

His other new one is of the same genus, a Chilobrachys huahini. There are no pictures of it yet, but it’s a little monster beast. It lives in a plastic deli cup filled with a giant ball of webbing and dirt, and crickets are dispatched before you can even blink. This one will apparently get rather large. We’ll definitely have to move, or at least build an extension, when everyone starts to grow up.

Speaking of growing up: several of our babies have now moulted! (See Wikipedia for more details, but basically: tarantulas get bigger by growing a new exoskeleton inside their old one; when the time is right, they work their way out of the old skin and can then stretch the new one to the bigger size before it hardens.)

Here are some of their new suits:

Greenbottle blue before:
A tiny tarantula, less than an inch big, sitting on a layer of dirt in its jar, surrounded by webbing. The spider has pale orange legs with black tips and an orange-striped black abdomen.
And after:
The same spider, but now a little bigger; it's perched on top of a piece of bark in its jar. The tiger stripes on its back are much more orange than before, and its carapace looks almost golden.

Mort before:
A small brownish tarantula sitting in a plastic tub filled with coconut fibre, on top of a flowerpot turned sideways to make a hide.
And after (not a great picture — he’s gone very shy):
The same spider as above, but now bigger; its abdomen is now black, and its legs almost span the flower pot.

Chaco Golden Knee before:
A plastic tub filled with moss and a bit of fake plant; underneath the moss, a fuzzy leg and abdomen can just be made out.
And after (still not coming out!):
A larger plastic tub, with some dirt, a piece of bark and a fake plant; next to the fake plant, a fuzzy spider is stretched out; we can't be sure, but it might be bigger than the fuzzy thing in the previous picture.

And the one I’m most pleased about — my baby Merlin, before:
A small, bright blue spider, sitting huddled up at the top of a plastic tub. It can't be more than half an inch big.
And after:
The same spider as above, but bigger -- maybe an inch now. It's sitting in a tube web at the top of its tub, dangling its legs down.

Isn’t that just the cutest spider in the world? (Just say yes.)

Mr Satu’s OBT and Skeletor also moulted at the same time as this lot, but they’re both too shy to have their picture taken (the OBT teases me by lounging out in the open, only to bolt as soon as I pick its jar up; Skeletor just hides). And just this morning, the Indian Violet did, too. It won’t be long before Socks’ moult now; her abdomen has turned very dark, which is basically the new skin getting ready under the old one. After that, it doesn’t usually take more than a week or two before the moult. It’ll be exciting to see such a big one doing it!

The final bit of news to report is that we’ve rehoused the P. miranda. Before, the spider looked like this:
A long-legged, fuzzy-looking grey and white tarantula, sitting in a corner of a plastic tub next to a piece of bark; it seems to be looking right at the camera.
Now, this is all we get to see:
A close-up of the corner of a glass tank. There are pieces of bark against its back, and a small gap between bark and glass side; spider webs cover the opening to this little cave, but there's no sign of the actual spider.

We think it likes its new tank. It certainly seems to enjoy the crickets we throw in there, and is doing very interesting things with webbing and dirt. Sometimes we can just about see a fuzzy leg or two in the back of the cave. At least the spider is happy!

Edited to add: after I’d posted this last night, Mr Satu decided to actually check on this one — and it turns out it moulted, too. It’s still basically all legs, but longer:
The back of the previously seen enclosure. The spider is sitting in a gap between pieces of cork bark, its stripy back legs and patterned abdomen sticking out.

On the far right you can just about see a bit of its cast-off moult. How we’re ever going to get that out, I don’t know.

And finally, an unidentified tarantula that we found in our bed:
A stuffed toy tarantula with a brown abdomen, black carapace, pink and white knees and black feet. It's sitting on top of a white and blue blanket.

It hasn’t shown any interest in crickets, and seems to be pretty happy just sleeping all day. It’s also very tame — it hasn’t tried biting or kicking hair once yet! I think we’ll keep it and call it … umm … Spidy!
