bedded in the tissue of the host and enables the 
copepodite and following attached larval stages 
to remain attached to the host without using 
their appendages. At least four of the six chal- 
imus stages that follow the copepodite remain 
attached to the host by the frontal filament; the 
fifth and sixth chalimus stages may either be 
found attached or free on the host. The adult is 
found moving freely over the surface of the 
host.
