The walrus, the "true seals" and the "eared seals" or "walking seals". There are 7 species of sea lions, and 9 species of fur seals that make up the "eared seals". Eared seals differ...
Although sea lions do not make a wide range of sounds, they are very noisy, and easily one of the most vocal mammals on Earth. Anyone who has observed large groups of sea lions sunning themselves on beaches or piers, knows that not only is there a continual racket while the animals move about to find good resting spots, but even while they are appa...
Some sea lion colonies are permanent residence throughout their range, while other species are partially migratory. The California sea lion may or may not migrate. Many females live on barrier islands year round, raising their pups in large daycare groups with multiple motherskeeping an eye out for danger. Most males migrate back to the mainland wh...

May 21, 2007 · The highest ganglion cell density in the sea otter approaches 4,000 cells/mm 2; in a rather small eye of the sea otter, this corresponds to 50–60 cells/deg 2. CONCLUSION In general, the visual system of marine mammals demonstrates a rather high degree of development and also several specific features associated with adaptation to both aquatic and aerial environment.

Pinnipedimorpha, which includes seals, sea lions, and walruses, also possess a form of nictitating membrane, although in seals, for instance, this membrane can be fused with the eyelid, adapting to their amphibious lifestyle. This contrast highlights the evolutionary diversity of the nictitating membrane among aquatic and terrestrial animals.
