Features of behavior, birthing process, pups nursing of Weddell seals were studied.
Studies of the growth (at birth to 21 days age) of young seals were conducted. Seven seals born in the “Akademik Vernadsky” station were used in the experiment (two males and five females). They were weighed every three days. The live weight was determined by using the obtained data in different periods of growth and its absolute, average and relative growths.
