GASTROTRICHA Meaning and
Definition
-
Gastrotricha are a phylum of small, aquatic microinvertebrates. The name "Gastrotricha" is derived from the Greek words "gastro" meaning stomach, and "tricha" meaning hair, which reflects the characteristic arrangement of cilia on their ventral surface. These organisms are widely distributed across freshwater and marine environments, as well as in moist terrestrial habitats such as mosses and leaf litter.
Gastrotricha are typically small in size, measuring between 100-1200 micrometers in length. They possess a cylindrical body covered in a cuticle, which is usually ornamented with scales or spines. The distinctive cilia that cover the ventral surface serve various functions, including locomotion, feeding, and sensory perception.
Feeding habits among Gastrotricha vary, but most species are characterized as either carnivorous or detritivorous. Carnivorous species possess a proboscis that functions to capture and ingest small prey, while detritivorous species primarily feed on particulate matter and decomposing organic material.
Reproduction in Gastrotricha is typically sexual, with separate sexes present in most species. Some species have complex life cycles that involve alternating sexual and asexual stages, while others are strictly asexual. Fertilization occurs internally, and the fertilized eggs are either brooded or laid externally. The embryos develop into miniature adults directly, without undergoing a larval stage.
Due to their unique anatomical features and ecological significance as both predators and decomposers, Gastrotricha play an important role in various aquatic and terrestrial ecosystems, contributing to nutrient cycling and food webs.

Etymology of GASTROTRICHA
The word "Gastrotricha" has a Greek origin. It comes from combining two Greek words: "gastro" meaning "stomach" or "belly", and "tricha" meaning "hair" or "bristle". Therefore, "Gastrotricha" translates to "belly bristle" or "stomach hair", referring to the presence of cilia or hair-like structures on the belly side of these organisms. Gastrotricha is a phylum of small aquatic invertebrates.
