Tiger shark tagging. Tagging device on the back of a tiger shark (Galeocerdo cuvier). The remora fish attached to the shark at lower right uses its host for transport and protection benefits. It also scavenges on food dropped by the host. Tagging is used to study populations and movements. Photographed on the Aliwal Shoal reef, South Africa.
