Home range and habitat use of the olive sea snake, Aipysurus laevis, on the Great Barrier Reef , Australia

Short-term movements of 12 olive sea snakes were tracked using ultrasonic transmitters fed to snakes. This species redistricts itself to a home range of about 1500-1800 m2. Three individuals displaced from their home ranges did not home to them. The home range often is linear along a reef face where the reef abuts open sand. Snakes forage by investigating crevices in coral or rock but do not linger over open sand. Home ranges of individuals broadly overlap. No territoriality was displayed.
