"Rhabditiform" Pronounce,Meaning And Examples

"Rhabditiform" Meaning

The word "rhabditiform" refers to a specific stage in the life cycle of some nematode worms, such as roundworms. It is the first, juvenile stage of development after hatching from eggs, characterized by a slender and elongated body shape. At this stage, the worm has a distinct head and a long, muscular pharynx. The rhabditiform stage is typically free-living and completes two moults before progressing to the following stage, known as the third-stage infective larvae or filairiform, which is capable of infecting and migrating into a host through the skin.
