Animalia
General characteristics



The body segmented, the segments usually grouped in two or three rather
distinct regions.
Paired segmented appendages (from which the phylum gets its name).
Bilateral symmetry.
A chitinous exoskeleton, which is periodically shed and renewed as the animal
grows A tubular alimentary canal, with mouth and anus.

The circulatory system an open one, the only blood vessel usually being a
tubular structure dorsal to the alimentary canal with lateral openings in the
abdominal region.

The body cavity a blood cavity or hemocoele, the coelom reduced.

The nervous system consisting of an anterior ganglion or brain located above
the alimentary canal, a pair of connectives extending ventrally from the brain
around the alimentary canal, and paired ganglionated nerve cords located
below the alimentary canal.

The skeletal muscles striated (except in the Onychophora).

Excretion usually by means of tubes (the Malphigian tubules) that empty into
the alimentary canal, the excreted materials passing to the outside by way of
the anus.



Respiration by means of gills, or tracheae and spiracles.
No cilia or nephridia (except in the Onychophora).
The sexes nearly always separate.
