DIVING BEHAVIOR OF THE SAIMAA RINGED SEAL ( PHOCA HISPIDA SAIMENSIS NORDQ.)
A bstract The activity and diving patterns of four adult Saimaa ringed seals ( Phoca hispida saimensis , a landlocked subspecies living in Lake Saimaa, Finland) were examined during spring, summer, and autumn by the use of VHF‐transmitters. Over 17,000 dives were registered. The duration of the dive...
