20.4A large cooler used as a holding tank for anaesthesia and clinical handling of small bamboo sharks. The lid is propped open to: keep the air line patent; allow for passive observation of the animal; and minimize sudden changes in light intensity. This also allows easy monitoring with a dissolved oxygen meter.
