This did not happen in 2008, possibly because the shark feed protocol seemed more disciplined and the sharks better “trained.” Several habitats that were not visited in 2004 were surveyed in 2008, such as the channel at the west boundary of SRMR and an area of sand and patch reefs at 33 meters depth.
