Ringed seals have a diel haul-out pattern in which they spend more time hauled-out during the night, an uncommon feature among pinnipeds. [ 9 ] [ 13 ] Hauling-out spikes an increase in the herding behaviour of ringed seals, particularly in the Ladoga subspecies. [ 14 ]
The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic ...
They feed mainly during twilight and at night, when golomyankas occur in depths as shallow as 10–25 m (33–82 ft). [1] [4] During the day, golomyankas are typically found deeper than 100 m (330 ft). [1] Baikal seals can dive up to depths of 400 m (1,300 ft) [4] and stay underwater for more than 40 minutes. [1]
Elephant seals are shielded from extreme cold more by their blubber than by fur. Their hair and outer layers of skin molt in large patches. The skin has to be regrown by blood vessels reaching through the blubber. When molting occurs, the seal is susceptible to the cold, and must rest on land, in a safe place called a "haul out". Northern males ...
There’s a reason the male elephant seals lounging on the sand look a bit ratty. Bull elephant seals take over SLO County beaches. How will they spend the rest of summer?
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
"I woke up around 2:30 a.m. and heard snoring and sneezing," said sailor Michael Duffy.
The southern elephant seal was one of the many species originally described by Swedish zoologist Carl Linnaeus in the landmark 1758 10th edition of his Systema Naturae, where it was given the binomial name of Phoca leonina. [3]
