A widow's peak is a V-shaped point in the hairline in the center of the forehead. Hair growth on the forehead is suppressed in a bilateral pair of periorbital fields. Without a widow's peak, these fields join in the middle of the forehead so as to give a hairline that runs straight across.

The widow spiders (genus Latrodectus), such as the black widow, redback spider, and katipō are spiders that carry a neurotoxic venom [18] which can cause a set of symptoms known as Latrodectism. Widow spiders are large, shiny house spiders with relatively spindly legs and deep, globular abdomens.
Steatoda nobilis has a brown bulbous abdomen with cream coloured markings that are often likened to the shape of a skull. [11] Their legs are reddish-orange. [12] Both female and male S. nobilis can be distinguished from other spiders of the same genus by their large size and typical colouration.
