Female black widows are shiny black, with a red-orange hourglass pattern on their abdomen. Male black widows are not black, but brown or gray with small red spots. Black widows are poisonous arachnids—animals that have a skeleton outside their body, a segmented body, and eight jointed legs. They are not insects. Their deadly poison is said to be 15 times stronger than rattlesnake venom. Black widows use a silk-like substance to weave tangled-looking webs, typically close to the ground in covered or dark places, such as near drain pipes or under logs. The female hangs upside down in the web to await her prey, exposing her bright markings as a warning to potential predators. The black widow senses vibrations to the web. When an unlucky intruder gets trapped, the spider immediately begins weaving its glue-like webbing around it. Insects such as flies, mosquitoes, or even larger prey like grasshoppers are typically caught. Once captured, the black widow injects its victims with poison, paralyzing them. The tips of the black widow’s legs are coated with an oily substance that prevents the black widow from getting caught in its own web. Adult male and female black widows live solitary lives, meeting only to breed. The female black widow lays approximately 200 eggs. The eggs incubate for some 20 days in a small, round papery sac that’s attached to the mother’s web. After hatching, the baby spiders stay in the cocoon for up to one month. Three species of poisonous North American spiders carry the common name black widow under the genus Latrodectus. Each species occupies a distinct region of North America, as their names suggest: Eastern black widows (L. mactans), northern black widows (L. variolus), and western black widows (L. hesperus). These three species have very similar physical and behavioral characteristics. The name “black widow” comes from the female’s habit of eating the male after mating.
The female black widow is approximately 1.5 inches (38 millimeters) long. The male is about half the female’s size.
The black widow is prey for birds and other spiders. Although poisonous, the black widow is not considered aggressive unless threatened. In fact, the male black widow is reclusive and hardly ever seen by humans. While the black widow’s poison is rarely fatal to humans, it can cause severe pain and nausea.

The mountain lion goes by many names, including cougar, catamount, panther, red tiger, deer tiger, and puma. This cat can be found throughout much of South and North America. The mountain lion used to be found all over the United States, but now is primarily seen in the western U.S. An endangered subspecies of mountain lion also remains in Florida. These felines are comfortable in many different habitats and, aside from humans, have the widest geographic range of any land mammal in the Western Hemisphere. In North America, mountain lions eat mainly deer, but they also eat smaller animals, such as mice and rabbits. These cats have a poor sense of smell, but have excellent vision and hearing that help them hunt in the early morning and evening hours. Their powerful hind legs enable them to jump as far as 40 to 45 feet (12 to 13 meters). This carnivore stalks its prey until an opportunity arises to pounce. Mountain lions “cache” their prey, or hide it under leaves and soil, where they can come back and feed on it over the course of several days. Mountain lions don’t roar, but females have a loud scream, which is believed to attract males. Females have an average of two to four cubs per litter and give birth in a den. The cubs are born with spots, which usually disappear by the time they are roughly nine months old. Their eyes also change from blue to yellow by the time they reach 16 months old. By 18 months, the young cats leave their mom to go fend for themselves. Because of their size, strength, and predatory skills, mountain lions are considered one of the “big cats.” Tigers, leopards, cheetahs, and jaguars are also part of this grouping.
