Summary Information
Taxonomic Classification Kingdoms / Animalia / Annelida (Annelid worms) / Hirundinea (Leeches)/ Rhynchobdellida / Glossiphoniidae / Theromyzon / Species:

(Classification of invertebrate species is an evolving discipline. The information in Wildpro has been carefully referenced to the source material, as far as possible. Readers requiring further clarification should consult the source materials and more recent publications. Classification information in Wildpro will be altered when clear and scientifically endorsed new information regarding taxonomic divisions becomes available to us.

This section is currently predominantly used in Wildpro to link different data types and demonstrate inter-relationships. It does not contain detailed information on the invertebrate organism itself.)

Description Nasal leech. Nasal leeches in general have been described as 10-45mm long if engorged, amber/olive to red if engorged, four pairs of eyes.(B15, B36.34.w34, B37.x.w1)
Systems affected Nasal leeches predominantly affect the nasal passages and choanae. Have also been recorded affecting the pharynx, trachea, eyes and the feet and legs. (B15, B37.x.w1).

"Nasal passages, conjunctival sac, pharynx, bronchi." (B91)

Life Cycle "Eggs enclose in cocoon attached to submerged rock or plant, covered by body of adult; eggs hatch in about 10 days, young attached to adult for 2-4 months. Young require blood meal for development, perhaps require total of three meals to reach maturity, leave host between meals; may survive at least nine months without feeding." (B91)
