Seal finger was first described scientifically in 1907. [4] [5] It can cause cellulitis, joint inflammation, and swelling of the bone marrow; untreated, the course of "seal finger" is slow and results often in thickened contracted joint. [3] Historically, seal finger was treated by amputation of the affected digits once they became unusable.
The seals can live for as many as 35 years in the wild while dealing with predators like orcas and larger leopard seals. They survive on fish, squid, and other smaller prey to survive.

Compared to deep-diving elephant seals, the iris of shallower species, such as harbor seals and California sea lions, does not change much in size between contraction and expansion. [54] Seals are able to see in darkness with a tapetum lucidum, a reflecting layer that increases sensitivity by reflecting light back through the rods. [55]
Sunlight and seawater cause the dark gray to become brown and the light silver to become yellow-brown, while long periods of time spent in the water can also promote algae growth, giving many seals a green tinge. The juvenile coat of the monk seal, manifest in a molt by the time a pup is weaned is silver-gray; pups are born with black pelage.
