Use of an acceleration data logger to measure diel activity patterns in captive white-tip reef shark, Triaenodon obesus.
Ultrasonic tagging and detection range: Nine white-tip reef sharks were fitted with ultrasonic transmitters (Vemco Ltd, V16-5H-A69-1303 delay range 60-180 sec) between May and October 2008 (Table 1).
Data downloaded from the receivers were used to assess the residency and diel pattern of white-tip reef sharks, within the study area.
This is consistent with the activity patterns of captive white-tip reef sharks recorded by Whitney et al.
Dan was a keen photographer who was passionate about white-tip reef sharks and the marine life of Galapagos Islands.
