Not quite a true spider, poor ambitious thing, mainly due to the monolithic construction of its oval body (as opposed to the bifurcation of spiders).  I don’t know whether you’ve had occasion to smell a Daddy Longlegs…it’s most rancid indeed when it wants to be, by secreting fluid from a pair of glands; I don’t recommend sniffing it, if you can avoid it.  A sidenote:  If you have several moments of curiosity more to invest in this topic, I highly recommend looking into the mating and egg-laying habits of the Daddy Longlegs…suffice it to say that protrubances are involved, from both sexes.  Well that, and both parents die shortly after breeding, so there’s a lesson to be learned in that as well.
