Missulena bradleyi

Danger: Dangerously venomous

Other Names: Bradley's Mouse Spider

Size: Male body 14 mm, Female body 20 mm

Family: Actinopodidae (Mouse Spiders)

Danger: Eastern Mouse Spiders can be deadly though it's much less likely than for a funnel web. Apparently they are not that agressive towards people. They do sometimes bite when disturbed, but they only rarely inject venom when they bite humans. Presumably they're conserving their venom, which they need to catch their prey. Their venom is somewhat similar to funnel web venom.

About the Eastern Mouse Spider

Eastern Mouse Spiders are smaller but look even more stockily built than funnel webs and trapdoor spiders. They look like the spider equivalent of the short guy who spends hours a day in the gym. They have absolutely massive fangs and fang bases compared to the size of the rest of the spider. I used to think that if they were larger, they might win a vote for the most frightening-looking of all spiders. Though now, after editing the up-close photos, I think their small narrow-spaced eyes make them look a bit goofy, and less scary than how I used to think of them.

Note that living mouse spiders would look blacker than the pictures of dead ones here, which would make them look more scary.

In the summer of 2015-16 a friend was sitting on her lounge feeding her young child..... when she was absolutely terrified to feel, and then see, a large black funnel-web-like spider crawling along her upper arm. She flicked it off her onto the floor and her husband caught it in a jar. The Australian Museum confirmed that it was an Eastern Mouse Spider. At least it wasn't a funnel web! If I remember correctly, it had been raining a lot and the mouse spider probably came inside to keep dry.

Note that dead spiders usually fade in colour, so nearly all the spiders will look blacker or darker in colour in real life than they do in the photos of dead spiders from the museum.
