Short description Morphology
Long, cylindrical trunk with prominent angular antero-dorsal hump clearly marked at posterior boundary of neck. Females with longer trunk length than males. Proboscis large, globular, wider than long, with prominent apical organ and sensory pits; hooks in all circles, with discoid roots; anterior hooks all at same level, longer than middle and posterior hooks. Long neck, wide posteriorly. Triangular brain, situated near posterior end of receptacle.
Adult fish host found near shore beyond surf zone; juveniles and recruits of host found inshore in estuaries. Sexually mature adult worms found in breeding hosts; may suggest that worms are affected by hormones of spawning hosts, as reported in other species of this group parasitic on big fishes in large bodies of water (Ref. 2417).
