Analysis of possibility of feeding of loggerhead turtles during internesting periods based on stomach temperature measurements
The presence of feeding was examined in loggerhead turtles during internesting periods from 1989 through 1993 off southern Japan using the Time Temperature Recorder (TTR). The TTR was inserted into the stomach and temperature data were obtained from the nine free-ranging female loggerheads. The patterns of temperature fluctuation which consisted of a rapid drop and subsequent gradual rise were recorded in the stomach temperature data. This typical pattern proved to be caused by drinking or feeding. The pattern counted 5 to 19 times in the first 24 hours after nesting and decreased afterwards gradually. The loggerheads seemed to drink sea water just after nesting and not to feed during internesting periods.
