🦭Baikal Seal
De Baikalrob of Nerpa (Pusa sibirica, verouderd Phoca sibirica) is een soort zeehond, die alleen voorkomt in het Zuid-Siberische Baikalmeer. Samen met twee ondersoorten van de ringelrob (Pusa hispida) is het de enige zeehond die enkel in zoetwater leeft. Hoe de dieren terechtgekomen zijn in het Baikalmeer, dat zo'n 1600 kilometer verwijderd ligt van de meest nabije kust, is onbekend. Waarschijnlijk stammen ze af van ringelrobben uit de Noordelijke IJszee, die via rivieren en meren het Baikalmeer hebben bereikt.
