DIPLEURULA Meaning and
Definition
-
Dipleurula is a term used in zoology to describe a specific larval stage found in certain groups of marine invertebrates. The term is derived from the Greek words "di-", meaning double, and "pleura", meaning side or rib.
The dipleurula larva is characterized by its bilaterally symmetrical body plan, which consists of two rows of ciliated cells known as bands that extend along both sides of the larva. These bands are connected by a ciliary band located at the anterior end. This larval form is typically planktonic and free-swimming.
The dipleurula larva is believed to be an evolutionary precursor to more complex life stages found in various marine invertebrates, such as echinoderms (e.g., starfish and sea urchins) and hemichordates. During metamorphosis, the dipleurula larva can undergo significant morphological changes to develop into the adult form of the organism.
The dipleurula stage plays a crucial role in the life cycle of these organisms, as it allows for dispersion in the ocean and the colonization of new habitats. It also facilitates the dispersal of reproductive cells and assists in the establishment of populations.
Overall, the dipleurula can be considered an important transitional stage in the complex life cycles of certain marine invertebrates, representing a temporary larval form that exhibits bilateral symmetry and aids in their development and survival in the marine environment.

Etymology of DIPLEURULA
The word "dipleurula" is derived from two Greek words: "diploos" meaning "double" or "twofold", and "eurys" meaning "wide" or "broad". The term was coined in the early 20th century by the German biologist Benno Reinhard Leopold Hatschek to describe a distinctive larval form found in certain marine invertebrates, particularly echinoderms and hemichordates. The name "dipleurula" refers to the bilateral symmetry and the broad, flattened shape of this larval stage.
