Monachinae(known colloquially as "Southern seals") is a subfamily ofPhocidaewhose distribution is found in thetropical,temperateandpolar regionsof thesouthern hemisphere,though in the distant past fossil representatives have been found on both sides of theNorth Atlantic Ocean.[1][2]The difference between members of this group and members ofPhocinaeis in monachines the hindclaws are greatly reduced in size.[3]Furthermore, all species have 34chromosomes.[3]There are three tribes recognized here:Monachini(monk seals),Miroungini(elephant seals), andLobodontini(Antarctic seals and a handful of Afroamerican fossil genera).[4][5]While today represented by eight extant andone recently extinct species,Monachinae had an incredibly enriched fossil diversity that went into decline soon to be replaced by southern species ofsea lionsandfur seals.[6][5]
