These were two very small and poorly developed cucullanid larvae and it was not possible to identify them to species. Perhaps, they represent new infections, or this fish acts as paratenic host. These are the first cucullanid nematodes reported from C. ignobilis   and the family Carangidae   in the Indo-Pacific Ocean.
