%X Acoustic telemetry techniques have been adapted for use with small boats to facilitate  tracking of nearshore reef species. In addition to permitting tracking in areas where  manoeuvrability and quick responses are required, the system has modest operating  costs that make tracking experiments a viable option for a wide range of researchers.  Tracking and communication equipment can be powered for several days by a single  12-V 8D truck battery. Current topics in shark biology that are amenable to these tracking  techniques are discussed. For instance, hammerhead pups have been tracked on their  natal grounds for periods of up to 13 days.  Their daytime movements appeared to be restricted to a well defined 'core area' where  a school of sharks hovered between 1 and 3 m off the lagoon floor. At night, the sharks  became more active, expanding their range of movements before returning to the core  area the next morning.
