Abstract: The effects of temperature within the range 20°C to 30°C, on rate of passage of material through the gut were studied in juvenile captive loggerhead turtles ( Coretta caretta). Total gut clearance time (TGCT) decreased with increasing temperature (Q10 = 1 .6). The difference in value of TGCT was greater between 20°C and 25°C, where it fell by 33 hours, t han between 25°C and 30°C. where it decreased by 6 hours. At 25°C and 30°C the satiation rat ion amounted to 3. 73 per cent body weight; at 20°C the value was only 0.92 per cent. It was calculated that appetite would return to satiation level at a faster rate at 20°C than at 25°C or 30°C.
Food was retained in the oesophagus of juvenile loggerhead turtles for up to one hour after feeding.
