Biology and ecology

Lives in salt lakes. 

The animals are characterised by a deep furrow on each side of the head, and a suprapedal fold around the sides of the foot. Movement is by steps. The snout is long. The eyes have a cluster of glands above them. Coxiella are dioecious. Development is direct. Females are oviparous, depositing eggs singly in capsules coated in sand or mud. Coxiella probably feed on organic detritus.They are amphibious.
