Origin of arthropodarthro- + -pod
The definition of arthropod is an animal without a back bone, with six or more jointed legs, a segmented body and a supporting structure on the outside.
An example of arthropod is a scorpion.
any of the largest phylum (Arthropoda) of invertebrate animals with jointed legs, a segmented body, and an exoskeleton, including insects, crustaceans, arachnids, and myriapods
Any of numerous invertebrate animals of the phylum Arthropoda, including the insects, crustaceans, arachnids, and myriapods, that are characterized by a chitinous exoskeleton, a segmented body, and jointed appendages.
Origin of arthropodFrom New Latin Arthropoda phylum name arthro- New Latin -poda -pod

(plural arthropods or arthropodae)
- The great Arthropod class, the Crustacea, presents to the zoologist at the present day an immense range of forms,.
- The essential difference between these two kinds of eye appears to be that the Chaetopod eye (in its higher developments) is a vesicle enclosing the lens, whereas the Arthropod eye is a pit or series of pits into which the heavy chitinous cuticle dips and enlarges knobwise as a lens.
- The principal forms assumed by the Arthropod parapodium and its rami may be thus enumerated: (1) Axial corm well developed, unsegmented or with two to four segments; lateral endites and exites (rami) numerous and of various lengths (certain 8 limbs of lower After Lankester, Q.
- It is not true that all the biting processes of the Arthropod limb are thus produced - for instance, the jaws of Peripatus are formed by the axis or corm itself, whilst the poisonjaws of Chilopods, as also their maxillae, appear to be formed rather by the apex or terminal region of the ramus of the limb; but the opposing jaws (= hemignaths) of Crustacea, Arachnida and Hexapoda are gnathobases, and not the axis or corm.
- (9) The corm becomes the seat of a development of a special visual organ, the Arthropod eye (as opposed to the Chaetopod eye).
