Pronunciation: [klˈas plˈakə͡ʊdəmˌi] (IPA)

The term "Class Placodermi" refers to a group of extinct, armored fish species that existed from the early Devonian to the end of the Carboniferous period. The word "placodermi" is spelled as "pləˈkoʊdərmi" in IPA phonetic transcription. The "placo" part comes from the Greek word "plax" meaning plate, while "dermi" means skin.

CLASS PLACODERMI Meaning and Definition

1. Class Placodermi refers to a group of extinct, armored jawed fish that lived during the Devonian period, approximately 460 to 370 million years ago. The name "Placodermi" derives from the Greek words "plax" meaning plate and "derma" meaning skin, highlighting the characteristic armored plates that covered their bodies. These prehistoric fish played a significant role in the evolution of vertebrates, as they were among the first jawed fish to emerge during the early stages of aquatic life.

   Members of the Class Placodermi exhibit a wide range of body forms and sizes, ranging from small, bottom-dwelling species to larger, more predatory fish. Their bodies were encased in tough, bony plates that provided protection against predators and external injuries. Some species possessed sharp spines or protrusions for offense and defense. Class Placodermi fish had jaws equipped with teeth, which allowed them to feed on a variety of prey such as smaller fish, invertebrates, and even plants.

   The fossils of Class Placodermi have been found in different parts of the world, including Australia, Europe, and North America. They were crucial in the early evolution of aquatic ecosystems, occupying various ecological roles and contributing to the diversity of marine life during their time. While no living descendants of Placoderms exist today, their evolutionary innovations, such as the development of jaws and teeth, laid the groundwork for the emergence of modern jawed vertebrates, including humans.

Etymology of CLASS PLACODERMI

The word "Class Placodermi" has its etymology rooted in Greek.

The term "Placodermi" is derived from the Greek words "plax" meaning "plate" and "derma" meaning "skin". This name was given to this extinct class of prehistoric armored fish because their bodies were covered with thick bony plates.

The word "Class" comes from the Latin word "classis", which means "division" or "grouping". In biological classification systems, a class is a taxonomic rank that groups together organisms with similar characteristics.

Therefore, the term "Class Placodermi" refers to a taxonomic category that includes the group of ancient fish characterized by their armored plates.
