Family #1: Actinopodidae
Pictured: Male Missulena occatoria. Image by Peripitus
Actinopodidae is a family of mygalomorph spiders, meaning they are a "primitive" group, sharing many physical traits of the oldest, most ancestral spiders. They are commonly known as mouse spiders, and can be located in both Australia and South America.
They build trapdoors rather than webs to hunt, snatching prey that wander too close to their dens. Some have beautiful red coloration on their carapace (head) and/or chelicerae (mouthparts), like this pictured male Missulena occatoria.
A fun fact about actinopodids is that some exhibit a behavior known as ballooning - in which the young spiderlings throw out a line of silk from their spinnerets and let it carry them into the air as a dispersal method. This is unusual to see in a mygalomorph, because they are generally more stout-bodied and heavy than their araneomorph counterparts (more on mygalomorphs vs araneomorphs in a future post!).
Actinopodids are not considered dangerous spiders. A 2004 study on the effects of their bite reported that while it is certainly quite painful, the very worst systemic affects appear to be headaches and possible nausea. If you were to ask my opinion, I suspect the large fangs, rather than the venom, are what causes the majority of the pain!

A Swimmer’s Break: The Underrated Component of Swimming Fast

The first group is overjoyed by the recess from the sport, a chance to stretch their land legs and live life a little less structured than they normally would. They […]
