text_A: Phocids are known as true or "earless" seals. These animals lack external ear flaps and are incapable of turning their hind-flippers forward, which makes them more cumbersome on land. In water, true seals swim by moving their hind-flippers and lower body from side to side. Phocids have thickened mastoids, enlarged entotympanic bones, everted pelvic bones and massive ankle bones. They also lack supraorbital processes on the frontal and lack calcaneal tubers. A 2006 molecular study supports the division of phocids into two monophyletic subfamilies: Monachinae, which consists of "Mirounga", Monachini and Lobodontini; and Phocinae, which includes "Pusa", "Phoca", "Halichoerus", "Histriophoca", "Pagophilus", "Erignathus" and "Cystophora".
text_B: If you see a picture of a seal with supraorbital processes, are you looking at a phocid?
NO.
