Diversity of trypanorhynch metacestodes in teleost fishes from coral reefs off eastern Australia and New Caledonia

A study of trypanorhynch metacestodes in teleost fishes from coral reefs off eastern Australia and New Caledonia revealed 33 named species, including three undescribed tentacularioids, with over 100 new host records. The research found that lacistorhynchoid and tentacularioid taxa were predominant, while otobothrioid and gymnorhynchoids were less common. Notably, five trypanorhynch species exhibited low host specificity, suggesting broader ecological roles. The study also indicated higher diversity in larger piscivorous fish families and a 45% similarity between the fauna of the Great Barrier Reef and New Caledonia. Additionally, several extensively surveyed fish families showed no presence of trypanorhynch larvae.
