In a parasitic study on five Sharks (Carcharhinus macloti) caught from the Iranian coasts of Persian Gulf, two of five sharks appeared to have nematode in their intestine. Using light microscopy, the nematode was identified as Acanthocheilus rotundatus. A. rotundatus is characterised by 3.3-4.5 cm in length, semithick cuticle, small lips, semicircular and tri-lobed pseudolabia (not offset from...
