*Also known as the tongue worm
*A highly specialised [[Arthropods|arthropod]]
'''Recognition'''
*[[Oral Cavity - Tongue - Anatomy & Physiology|Tongue]]-like appearance
**Expanded anteriorly
*Adults are over 10cm in length
**Females measure between 30-130mm in length
**Males measure up to 20mm in length
*Transversely striated
'''Life cycle'''
*Life cycle takes '''6 months'''
*Adults inhabit the [[Nasal cavity - Anatomy & Physiology|nasal passages]] of dogs and sometimes cats
*Eggs are expelled by coughing and sneezing or are passed out with the faeces
*Herbivorous intermediate hosts ingest the eggs
*Eggs hatch in the herbivore [[Small Intestine - Anatomy & Physiology|intestine]]
*Larvae migrate to the [[Peritoneal cavity - Anatomy & Physiology#Mesenteries|mesenteric lymph nodes]] and encyst to become infective nymphs
**Cysts measure 1mm in diameter
*When a dog eats infected uncooked viscera the life cycle is completed
*Infective nymphs migrate from the viscera during chewing and crawl up into the [[Nasal cavity - Anatomy & Physiology|nasal cavity]] via the [[Soft Palate - Anatomy & Physiology|soft palate]]
*Infective nymphs mature to adults in the [[Nasal cavity - Anatomy & Physiology|nasal cavities]] and can survive for a year in the final host
'''Pathogenesis'''
*Causes [[Nasal Cavity Inflammatory - Pathology#Infectious causes of rhinitis|rhinitis]]
*Heavy infection leads to coughing, sneezing and nasal discharge[[Category:Crustacea]]
