PHYLACTOLAEMATA Meaning and
Definition
-
Phylactolaemata refers to a class of small, aquatic invertebrates belonging to the phylum Bryozoa, also known as moss animals. These organisms are characterized by the presence of tiny, box-like protective structures called phylactolaemate zooids, which are responsible for their name.
Phylactolaemata species are predominantly found in freshwater habitats including lakes, ponds, and slow-flowing rivers. They can also thrive in artificial water bodies such as ditches or reservoirs. These creatures are filter feeders, meaning they extract food particles from the surrounding water using a specialized structure called the lophophore. The lophophore consists of tentacles lined with cilia that create water currents, facilitating the capture of plankton and other organic matter for consumption.
Typically, Phylactolaemata colonies consist of numerous interconnected zooids that share a common feeding and reproductive system. Each zooid is housed within its own protective, irregular-shaped chamber or cystid, which it secretes through the excretion of calcium carbonate. These cystids can be clustered together to form intricate patterns on surfaces such as rocks, sticks, or vegetation.
Reproduction in Phylactolaemata involves both sexual and asexual modes. Asexual reproduction occurs through the budding process, where new individuals develop as outgrowths or buds from existing zooids. Sexual reproduction involves the release of eggs and sperm into the surrounding water, leading to the formation of free-swimming larvae that eventually settle and develop into new zooids.
Phylactolaemata play a vital role in freshwater ecosystems as primary consumers, contributing to nutrient recycling and the maintenance of water quality. They have also served as valuable model organisms in various studies, offering insights into colony formation, ecology,

Etymology of PHYLACTOLAEMATA
The word Phylactolaemata is derived from the combination of two Greek words: phylax and laimos. Phylax means guardian or protector, and laimos means throat or gullet. In zoology, Phylactolaemata is the name of a class of small, freshwater, tentacled animals called bryozoans. The name Phylactolaemata is given to these animals because their specialized structures around their mouths, known as lophophores, play a protective role by filtering food particles from the water. Hence, the name Phylactolaemata refers to these organisms as guardians of the throat.
