Fig. 1. (A) Diagram of a mako shark showing the positions of the temperature probes. The modified temperature loggers associated with the red (RM) and white (WM) muscle thermistors were attached to the body surface (1 and 2). The position of the stomach temperature logger is indicated by ST. (B) Transverse section (at 45 % FL, where FL is fork length) of a 10 kg mako shark showing the location of the heat-exchanging retia, the relative vertical positions of the RM and WM thermocouples and thermistors and the temperature logger in the stomach (ST). Note that the WM probes were posterior to the RM probes by 2 % FL.
