Halocercus pingi is a species of metastrongyloid lungworm nematode that parasitizes the respiratory tract of cetaceans.[1][2] It causes lethal pneumonia in young Indo-Pacific finless porpoise.[3]

Morphology

Halocerus pingi is a large, thread-like nematode with mostly smooth cuticles featuring fine annulations on anterior and posterior ends. It has 6 inconspicuous head papillae, a circular mouth, extremely short muscular esophagus, and two very long esophageal glands 5-7 times the esophagus length. Males possess a disc-like copulatory bursa with equal spicules. Females are viviparous.[1]
