The osteology of the Ross seal (Ommatophoca rossi) is defined. The bones of this species heavily resemble these of Leptonychotes, the single different Monachinae for which a common osteology is accessible. The hand and foot of Ommatophoca are particularly longer than these of alternative phocids, and a number of other features of this seal are adaptative alterations for swimming and for swallowing huge prey. attainable sexual discriminating features are mentioned.
