First case of a monitored pregnancy of a harbour porpoise (Phocoena phocoena) under human care

Blanchet, Marie-Anne; Nance, Tiffany; Ast, Colleen; Wahlberg, Magnus; Acquarone, Mario
Aquatic Mammals (2008)

Most of the data collected on the reproduction of harbour porpoises (Phocoena phocoena) comes from by-caught or stranded animals and is therefore opportunistic in nature. Harbour porpoises kept in a…
