Below is a transcript of the video sample provided for this module:
Black widow spiders have dark or shiny black bodies and often have a red or orange hourglass-like marking on their belly. In some cases, though, they have a pair of red spots or no markings at all. The body of the female black widow is about half an inch long and it may be about an inch and a half across including the legs. Males are about half that size. The web of a black widow is not the typical symmetrical shape that we associate with spiders. Instead, the web of a black widow is uneven and irregular. Seeing a web like this is a signal to be cautious.
