Stays in sediment in daytime and is most active at night, either hopping across the substratum or swimming in lower part of water column. Swimming and digging in the sediment are accomplished by synchronous strokes of the antennae. In probable escape response to predators, it used its rather large furca to push itself into sand. Escape from sand was also accom
plished by a sudden push from the caudal furca, launching it into overlying water. In general, it burrowed only a few millimeters into the sediment.
