... all correlated. However, for a given dive, the number of wiggles and oesophageal temperature drops were lower than the number of beak-opening events. Our results suggest that recording beak opening is a very accurate method for detecting prey ingestions by diving seabirds at a fine scale. However...

... that, in addition to the changes reported earlier, after parasite emergence (post-emergence), Manduca sexta larvae also showed marked deficits in their ability to ingest food because of a disruption in the function of the frontal ganglion that results in a significant slowing or the absence of peristaltic activity...

...R. J. A. Wilson; W. B. Kristan, JR; A. L. Kleinhaus ABSTRACT During the consummatory phase of feeding, in which blood is ingested, medicinal leeches display a characteristic set of behaviours: they extend their jaws, are less responsive to sensory input, produce mucus, relax the body wall...

..., with regard to determination of the time of prey ingestion as well as the number of prey items ingested and their masses. Units were deployed in nine species of free-living seabirds, where feeding conditions were uncontrolled, eight species of captive seabirds, where feeding conditions could be partially...

...Charles M. Lent; Karsten H. Fliegner; Edward Freedman; Michael H. Dickinson ABSTRACT Ingestion lasts 25 min in Hirudo medicinalis and is characterized by pharyngeal peristalsis which fills the crop. This peristalsis has an initial rate of 2·4 Hz which decays smoothly to 1·2 Hz at termination...

...C. M. Lent; M. H. Dickinson ABSTRACT Hungry leeches, Hirudo medicinalis , ingest blood meals averaging 890% of their mass in 29min. Ingestion is terminated as a result of distension of the body: experimentally distending leeches as they feed causes an immediate cessation of ingestion and inhibits...

... of Biologists 1984 Gas exchange ingestion tadpole The gills and associated respiratory pumps of many aquatic vertebrates either function directly in feeding or cease normal operation temporarily when feeding occurs ( Lauder, 1984 ). Thus, feeding and respiration in the buccopharynx may pose...
