My recent research has explored behavioral, physiological, and phylogenetic aspects of sociality in huntsman spiders (Sparassidae). Compared with solitary species, the findings reveal, the social species live in larger permanent family group retreats until the offspring are up to a year old, have egg sacs plastered to surfaces so they can't be moved and begin foraging later in their development.
