The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification.

"Patriarchy at work," quipped Gellar, later wondering how the spiders "get it back." Said Meyers, "I don't think they're re-attachable penis spiders." "I have to go look further now," said Gellar ...

[ 2 ] Its bite can cause severe symptoms, including increased pulse, blood pressure, and respiratory rate; extraordinary pain; penile erection that lasts for several hours ; and, in several documented cases , death.
Typically, female funnel-web spiders are larger than their male counterparts. Australian Reptile Park employees thought Hemsworth was a female at first due to his size.
They cooperatively capture and feed on prey caught in the web. Upon reaching sexual maturity, the young spiders leave the web, move a short distance away and exhibit solitary behavior. [3] The genus exhibits sexual dimorphism, males range in size from 3.5 to 4 mm while females are slightly larger ranging from 4 to 4.5 mm.
