What specialized structure do mature male *A. seemanni* possess on their first pair of legs utilized during copulation?
Answer
A tibial hook or spur
Mature males of the *A. seemanni* develop specialized appendages directly related to their singular focus on reproduction. On their first pair of legs, males possess a structure called a tibial hook, or spur. This hook is functionally vital during the mating process. The male uses this hook to securely latch onto the female's fangs during the vulnerable act of insemination. This gripping action serves to stabilize the female and physically prevent her from striking the male with her venomous fangs while he deposits sperm.
