| Summary: | Abstract Two captive otter cubs ( Lutra lutra ), born in October 1992, were followed throughout 9 months, from January to September 1993, in order to study the ontogeny of swimming, hunting and sprainting activities. Cubs were able to swim as adults do at 9 months old. First observed attempts at independent hunting and sprainting occurred when they were 3 and 6 months old respectively, but cubs were not completely proficient at these activities until they were 8 months old. Riassunto Dati preliminari sull'ontogenesi di alcune attività comportamentali di cuccioli di lontra in cattività - Due cuccioli di lontra ( Lutra lutra ), nati in cattività nell'ottobre 1992, sono stati seguiti per 9 mesi, da gennaio a settembre 1993, con lo scopo di studiare l'ontogenesi di nuoto, caccia e marcamento. I cuccioli erano in grado di nuotare come gli adulti a 9 mesi d'età . I primi tentativi di caccia e marcamento indipendenti sono comparsi rispettivamente a 3 e 6 mesi e sono stati definitivamente acquisiti a 8 mesi di età. |
