Black widow spiders produce venom. It is poisonous, affecting the nerves of its victim. The spider bite causes intense pain, muscle spasms and sometimes difficulty breathing. The venom disrupts how nerves communicate with each other. Their bites are rarely deadly. Black widows build webs to catch insects like flies and mosquitoes. They immobilize their meal with their venom. Then, they eat them.
Females lay their eggs in silken egg sacs, and then they guard the sac for 20 to 30 days before the eggs hatch. Then, the spiderlings stay just a bit longer. Once they leave, they are on their own.
Thorny Devil
The thorny devil boasts a striking appearance. It has many small, conical spines. This gives it a rugged, thorny appearance that serves as both protection and camouflage. They provide a physical barrier against potential threats. The thorny devil's brown color also helps it blend into its sandy desert environment.
Furthermore, the thorny devil has a false head. It is on the back of its neck. When threatened, it tucks its real head between its forelegs. It also raises its false head. This confuses its predators, like birds of prey, snakes, dingoes and foxes.
The thorny devil has grooves in its skin that channel water toward its mouth. This allows it to drink from dew or rainfall. This remarkable ability enables the thorny devil to survive in regions with scarce water and extreme temperatures. This creature can be found in Western and Southern Australia.
