As a gaming hit, the Razer BlackWidow has become an icon for RGB lighting. It features a standard QWERTY layout and RGB lighting that can display 16.8 million colors. This makes it one of the best options for a gaming keyboard that can look as good as it functions.
There is also the BlackWidow X which is a slightly cut down model of the original. The difference is that the X Chroma doesn't have the audio pass through or USB pass through and it doesn't have dedicated macro keys.
The Black Widow and BlackWidow X are both excellent options for anyone looking for a solid RGB keyboard. They both feature clicky Razer Green mechanical switches and Chroma LED back lighting with 16.8 million colors. The only real difference between the two is that the X Chroma doesn't come with the audio pass through and front USB pass through, which could be an issue for some users.
In all black widow species, "the females are the most distinctive, with shiny black bodies and a red hourglass-shaped mark on the underside of their round abdomen," Jo-Anne Nina Sewlal told Live Science in 2014. However, the marking can be orange-yellow as well. Males are smaller than females, and they typically build their nests closer to the ground and in secluded places like mouse holes, woodpiles, or the bottom part of a shrub.
The bite of a black widow spider is very dangerous to humans, but it rarely kills them. It contains a toxin called alpha-latrotoxin that swiftly overwhelms nerve cells, causing intense pain and swelling. But, unlike rattlesnake bites, they don't often cause paralysis or respiratory failure, according to the National Library of Medicine.
