Dolfijnen in OceanenEr zijn 26 soorten 'dolfijnen in oceanen' verdeeld in 12 veschillende groepen. Elke groep heeft zijn eigen pagina met informatie over elke afzonderlijke soort. Sommige groepen (waaronder over de groepen Delphinus, Grampus, Lagenodelphis, Orcaella, Sotalia, Steno, en Tursiops) hebben slechts een soort. Er is zeer uitgebreide informatie in de pagina's over de groepen Delphinus (tuimelaar) en Tursiops (gewone dolfijn), omdat zij de belangrijste soorten zijn die bovendien ook het meest besproken zijn in de website. Door lineair door deze sectie heen te navigeren zul je elke soort van elke groep in alphabetische volgorde doorlopen. | ||||||||||||
