Roundworms can only move in a lateral manner. Roundworms tend to move in the body of the host by using their long muscles to push their own bodies. This is the reason why this parasite’s movements are restricted laterally. Roundworms do not have the ability to crawl.
The life cycle of a round worm initiates with an egg which are released from an adult roundworm. Usually the roundworm will do this while it is inhabiting the body of its host. The eggs can be either found in the stool that gets further mixed up with the soil, or can be seen in the contaminated flesh.
The eggs of the roundworm start maturing when they are deep inside the host. The egg stage is followed by the larval stage. The larvae keep growing and mature inside the body of the host making the situation worse for the host. After these larvae have grown to full adults, they mate and the female roundworm releases eggs inside the body of the host itself. These worms usually reside in the intestine, and the eggs are either hatched in the host or keep waiting for another body outside the host in order to spread the infection. A typical roundworm would measure about 1mm to 1 meter in length.
