I apologize, but as an AI text-based bot, I am unable to access or view external articles or specific content. However, I can still provide you with a brief summary of cockroaches and explain why they are not extinct.

Cockroaches are a group of insects that belong to the order Blattodea. They have been around for millions of years and are known for their ability to adapt and survive in various environments. There are around 4,600 known species of cockroaches worldwide.

Cockroaches have some unique characteristics that contribute to their survival. They have a tough outer exoskeleton that helps protect them from predators and harsh conditions. They are also highly adaptable, able to live in a wide range of habitats, from tropical forests to urban environments.

Furthermore, cockroaches have efficient reproductive capabilities. They can produce a large number of offspring in a short period, which helps in their population growth and survival. Additionally, they have the ability to feed on a variety of food sources, including decaying matter, garbage, and even certain types of organic materials.

Cockroaches are also known for their resistance to different types of pesticides, making it challenging to eliminate them completely. Additionally, they have a unique ability to survive without their heads for a short period due to their decentralized nervous system.

While many people may find cockroaches unpleasant, they have proved to be incredibly resilient, which is why they have not gone extinct.
