0 the long nose of some animals, or the long tube-like mouth of some insects:
An elephant's trunk is a proboscis.
The immune response mounted by fish hosts is unspecific and essentially limited to the formation of a haemocyte capsule around the worm's proboscis.
Flies were dissected 27-46 days later and the midgut, proboscis and salivary glands of each fly were examined for the presence of trypanosomes.
The four proboscides and the two bothridia are fully formed, and the former are often protruded.
The leech still continues to harbour the trypanosomes; others present in the gut succeed those that disappear from the proboscis after each feed.
In both larvae and adults the distal portion of the reversible scolex proboscides bears small microtriches, 0-25 /ira long.
Cystacanths are encased in an envelope, and, with their proboscis invaginated, their overall body shape is roughly ovoid.
He therefore concluded that the mode of infection is contaminative through the tick's excreta and not active through its proboscis.
An aphid was recorded feeding if it was stationary with its proboscis inserted into the plant and its antennae pointing backwards.
