pediform

The variable first maxillae are seldom pediform, their function being concerned chiefly with nutrition, sensation and respiration.

Palpi four: anterior pair pediform, cheliform, or unguiculate; posterior pediform.

The fourth post-oral limb is a lobed plate, usually not distinctly segmented, and the fifth a uniramous pediform leg.

These, with the main stem more or less pediform, have the epipod and exopod modified for respiratory purposes.

They are frequently organs of attachment in parasitic Copepoda, and they may be completely pediform in the Ostracoda.
