| Abstract |
Observations were made on the dive behaviour of a solitary wild juvenile male bottlenose dolphin between March-May 1985 off Pembrokeshire, Wales. Results indicated a mean dive duration of 55.3 sec with an average of 3.5 blows between dives at mean intervals of 10.5 sec. Maximum sustained free-swimming speeds observed declined linearly with duration periods up to 4 min, with observed maximum peak brief effort of 54 km/hr over 20 sec. For longer periods, sustained speeds fell between 4-20 km/hr. |
