Phaxas is a genus of small razor shells in the family Pharidae. Members of the genus have a pair of elongate valves and live in soft sediments on the sea bed. They have a muscular foot with which they can dig rapidly and a short siphon which they extend to the surface of the substrate. They are suspension feeders.
