tongue worm

n.

Any of various wormlike, sometimes tongue-shaped, parasitic invertebrates of the phylum Pentastomida, having a mouth surrounded by four hooks used to attach to the respiratory passages of reptiles, birds, and carnivorous mammals. Also called pentastome, pentastomid.

A blood-sucking parasite that infests the nasal cavity of carnivores; human disease is caused by Armillifer armillatus—usual host, snakes—and Linguatula serrata—usual host, sheep and goats; pentastomiasis is global in distribution; linguliasis or Halzoun’s disease is more common in the Middle East and results from eating poorly-cooked meat; the larvae cause pain, itching, sneezing due to transnasal migration, dysphagia, vomiting and lymphadenopathy; a large bolus of worms may cause fatal obstruction
