DROMAEOGNATHAE Meaning and
Definition
-
Dromaeognathae refers to a taxonomic suborder of birds that belong to the class Aves. The term Dromaeognathae is derived from the Greek words dromeas, meaning "runner," and gnathos, meaning "jaw." This suborder is characterized by certain anatomical features, particularly within their jaw structure.
Dromaeognathae includes several families of birds such as emus, ostriches, kiwis, and rheas. These birds are generally large and flightless, though they exhibit variations in body size and morphology. One distinctive characteristic shared by all Dromaeognathae is the presence of a palatal structure called the palatine perforation. This feature allows airflow to pass from the oral cavity to the nasal cavity while the beak is closed, facilitating the unique respiratory system found in these birds.
Additionally, Dromaeognathae possess other notable traits like reduced pectoral musculature, adaptations for running or flightlessness, and long legs. They also lay large, yolky eggs that often require both parents to incubate.
The taxonomic classification of Dromaeognathae places them as a sister group to Palaeognathae, another suborder of birds that includes the extinct moas and elephant birds, as well as the extant tinamous and ratites.
In summary, Dromaeognathae is a suborder of birds characterized by their specialized jaw structure, adaptation for running or flightlessness, and the presence of the palatine perforation. These birds include several families of large, mostly flightless species, with a unique respiratory system and reproductive traits.

Etymology of DROMAEOGNATHAE
The word "dromaeognathae" is derived from two Greek roots: "dromaeo" and "gnathos".
The Greek word "dromaeo" means "to run swiftly", which is derived from the Greek word "dromos", meaning "racecourse" or "running". This root is often associated with animals that are known for their agile and swift movements.
The Greek word "gnathos" means "jaw". It is commonly used in biological terms referring to the jaws or beaks of animals. The term "gnathus" is also derived from this root and is used in zoology to describe an anatomical structure, especially a wing-like protrusion, found in certain animals' genitalia.
In the case of "dromaeognathae", the term combines the two roots to describe a group of birds characterized by their swift movements and specialized jaw structure.
