BDELLOID Meaning and
Definition
-
Bdelloid refers to a unique group of microscopic organisms belonging to the class Bdelloidea, which are exclusively found in freshwater ecosystems. These organisms, known as bdelloid rotifers, are commonly referred to as "bdelloids." Bdelloids are multicellular invertebrates that exhibit a highly specialized anatomy and physiology.
One distinctive feature of bdelloids is their ability to reproduce asexually via a process called parthenogenesis, wherein unfertilized eggs develop directly into offspring without the need for mating or genetic recombination. This remarkable reproduction strategy allows bdelloids to colonize and thrive in a wide range of ecological niches.
Bdelloids are known for their exceptional survival capabilities. They can withstand extreme environmental conditions, such as desiccation (drying out), by entering a dormant state known as anhydrobiosis. During anhydrobiosis, bdelloids retract their bodies, lose nearly all body water, and enter a cryptobiotic state until favorable conditions for resuming activity arise.
These microscopic creatures are an important part of freshwater ecosystems, playing vital roles in nutrient cycling and decomposing organic matter. Their feeding habits vary but often involve filter-feeding, wherein they utilize specialized structures called corona that create water currents to capture tiny food particles.
The study of bdelloids has attracted considerable scientific interest due to their unusual genetic characteristics. Unlike most animals, bdelloid rotifers have a remarkable resistance to genetic recombination, leading to their evolutionarily ancient genome of high diversity and puzzling lack of males in their populations.
In summary, bdelloids are a fascinating group of microscopic organisms that have adapted remarkable survival strategies and reproductive mechanisms. Their ecological significance and unique genetic characteristics make them intriguing subjects of scientific research.

Etymology of BDELLOID
The word "bdelloid" is derived from the scientific genus name Bdelloidea, which is used to classify a group of microscopic animals called bdelloid rotifers. The term "Bdelloidea" was coined by the German biologist Ludwig Rau in 1844, combining the Greek words "bdellos" meaning "leech" and "eidos" meaning "form" or "shape".
This naming was inspired by the fact that bdelloid rotifers have a slender, elongated shape similar to that of a leech. Despite the visual resemblance, bdelloid rotifers are not related to leeches or segmented worms. Nonetheless, the term "bdelloid" has stuck and is commonly used to describe these unique animals.
