Arthropoda

Syllabification: Ar·throp·o·da
Pronunciation: /ärˈTHräpədə

Definition of Arthropoda in English:

A large phylum of invertebrate animals that includes insects, spiders, crustaceans, and their relatives. They have a segmented body, an external skeleton, and jointed limbs, and are sometimes divided among several phyla.
Example sentences
  • Tardigrades, close relatives of Onychophora and Arthropoda, possess ornamented armored exoskeletons in high predation marine environments.
  • The recently published Ecdysozoa hypothesis suggests a closer relationship of the Scalidophora, Nematode, Nematomorpha, Tardigrada, Onychophora, and Arthropoda.
  • Other ecdysozoan phyla include Nematoda, Tardigrada, and Onychophora; this classification thus removes onychophorans from the Arthropoda and makes them an outgroup.

Origin

late 19th century: modern Latin (plural), from Greek arthron 'joint' + pous, pod- 'foot'.
