| regional endothermy in a coral reef fish? | although a few pelagic species exhibit regional endothermy, most fish are regarded as ectotherms. however, we document significant regional endothermy in a benthic reef fish. individual steephead parrotfish, chlorurus microrhinos (labridae, formerly scaridae) were tagged and their internal temperatures were monitored for a 24 h period using active acoustic telemetry. at night, on the reef, c. microrhinos were found to maintain a consistent average peritoneal cavity temperature 0.16 ± 0.005 °c (s ... | 2012 | 22403736 |
