A cockroach is an insect that usually makes people feel disgusted. There are 4000 species of cockroaches, but only 30 are considered pests. Cockroaches can be found all over the world, in a variety of habitats. They can live in forests, caves, bushes, burrows, and even cities. Cockroaches are extremely ancient organisms. They have been on the planet for 350 million years. Cockroaches today are smaller and more diverse than their prehistoric ancestors. Cockroaches are not classified as endangered.
The size of cockroaches varies depending on the species. The American cockroach (found in homes) can grow to be 1.2 inches long, while tropical species can grow to be 3.6 inches long.
Cockroaches lived during the dinosaur era and could grow to be 20 inches long.
Cockroaches have survived for so long because they are extremely adaptable to changes in their environment.
Cockroaches, like scorpions, can survive nuclear war with no repercussions.
Cockroaches that live in close proximity to humans consume almost everything. Hair, glue, book covers, plastic, soap, and leather are all edible. Wild cockroaches consume organic waste and play an important role in ecosystem cleaning.
Cockroaches’ bodies contain vitamin-producing bacteria. Cockroaches get enough nutrients from these bacteria even when they eat low-nutritional-value human garbage.
Cockroaches can go for long periods of time without eating. They only require one meal per month.
Cockroaches have two sets of wings. The outer wings are tough and leathery, and they protect the body from predators. Inner wings are membranous and used for flight.
Although cockroaches are frequently seen running through apartments, they are actually extremely lazy. Cockroaches sleep for three-quarters of their lives.
Cockroaches spend the majority of their time hiding in small spaces. They can hide in crevices as thin as a few millimeters. A pregnant adult female requires 0.17 inches of space.
Cockroaches have six legs and more than eighteen knees. Legs with multiple joints represent adaptation to life in a variety of environments. Cockroaches can run and hide from predators very quickly because of their unique type of legs.
Cockroaches are difficult to catch because their legs have tiny hairs that detect even the slightest movement in the air.
Cockroaches are quick-moving creatures. When they detect danger, they can run at a speed of 31 inches per second.
Cockroaches can live without their heads for several weeks. This is possible because all other systems (circulatory, respiratory, etc.) remain functional. The cockroach will eventually die from thirst. It can’t drink water or eat food if it doesn’t have a mouth.
Female cockroaches keep their eggs in a special capsule called a “ootheca.” Some species let ootheca and eggs develop on their own, while others keep the eggs inside the body until they are ready to hatch.
