IPA: //koʊˈɛnərəs//
KK: /kəʊˈɛnərəs/
A larval form of a tapeworm that creates a cyst in the brain of animals, particularly affecting sheep and other ruminants.
The veterinarian diagnosed the sheep with coenurus, which was causing neurological issues.
Coenurus is derived from the Greek "koinos" (meaning common) and "oura" (meaning tail). The term refers to a type of larval stage of certain tapeworms that can be found in the common host animals, hence the name.
Think of 'common' ('koinos') and 'tail' ('oura') to remember that coenurus refers to a common larval stage of tapeworms.
