Ingestion of Plastic and Unusual Prey by a Juvenile Harbour Porpoise

摘要: Considerable quantities of plastic debris are found throughout the world’s oceans (e.g., Dufault and Whitehead, 1994), may impact a diversity species, including marine turtles, birds mammals (Laist, 1997). Since many species whales dolphins live in waters far from shore, sink upon death, opportunities to record instances ingestion by cetaceans infrequent. Despite this, there several cases where or other has been documented for cetaceans, with published reports existing 21 odontocetes We know an additional five which documented: killer whale (Orcinus orca; K. Evans, pers. comm.), northern bottlenose (Hyperoodon ampullatus; R. Michaud, comm..), finless porpoise (Neophocoena phocoenoides; C. Parsons, white-beaked dolphin (Lagenorhynchus albirostris; Kastelein, pantropical spotted (Stenella attenuata; Robertson, comm.). For most odontocetes, only one few records have reported. Here we document third reported case harbour (Phocoena phocoena), discuss factors that might contributed its ingestion.
