The giraffe weevil is a fascinating insect species found in Madagascar. One of its most distinctive features is its elongated neck, which is actually a modified antenna that protrudes from its head, giving it a giraffe-like appearance. Males engage in a unique behavior of using their elongated necks to fight each other for mates, with the longer neck providing an advantage in these battles. This remarkable adaptation is a result of sexual selection, where males with longer necks are more attractive to females and have a higher chance of mating.
