Characteristics
Phoxichilidiidae are generally small, with body lengths ranging from a few millimeters to a centimeter. They are characterized by their flattened, laterally compressed bodies and the presence of a distinctive pair of large, stalked eyes.

- A distinct pleon (the posterior part of the body)
- Seven pairs of pereopods (walking legs)
- Three pairs of uropods (tail appendages)
Environments
Phoxichilidiidae are found in a variety of marine environments, including:
- Shallow coastal waters
- Intertidal zones
- Seagrass beds
- Coral reefs
- Rocky shores
They are often associated with benthic (bottom-dwelling) habitats.
