Des araignées qui vomissent des toxines sur leurs proies
Certaines espèces d'araignées non venimeuses, à l’instar des Uloboridae, neutralisent leurs proies en régurgitant sur elles des toxines plutôt qu'en les mordant. Cette technique de chasse leur permettrait d’immobiliser d’autres insectes, comme le révèle une étude menée par le Département d’écologie et évolution de l’UNIL et publiée dans «BMC Biology».
I was just poking around the garden today in a spare moment and had two unexpected arachnid discoveries!!
1. A hackled orbweaver (_Uloborus glomosus_), one of the very few venomless spiders, that also makes orb webs with a fuzzy, glueless silk not often used for aerial webs—I rarely come across them and never, I think, in my own garden.
2. A new kind of pseudoscorpion—not the tiny yellowish cthoniids I'm used to, but a HUGE beast with sturdy claws, like 3mm long! I think it's family Chernetidae.

Marc Robinson-RechaviDo you know that there are non-venomous spiders? This project started from a 1931 hand-drawn observation that Uloboridae spiders do not carry a functional venom system.
With histological, RNAseq and bioinformatics work led by the great Giulia Zancolli and master student Xiaojing Peng, we confirm that Uloboridae 🕷️ have lost venom glands , but find that they produce putative neurotoxins in the digestive gland. #EvoDevo #spider #Uloboridae #GeneExpression #venom #toxin

Axel SteinerDie Gewächshaus-Federfußspinne (Uloborus plumipes) findet man in fast jedem Baumarkt an Kakteen usw.
Ich habe die 5 mm kleine Spinne auf meiner Fensterbank angesiedelt und konnte sie beim Beutefang beobachten.
