Hauling-out

[4][5] Other benefits of hauling out may include predator avoidance, thermoregulation, social activity, parasite reduction and rest.

[7] Weddell seals are high latitude Antarctic inhabitants, allowing them to haul-out onto ice as adults year round for foraging.

[7] Similar to other pinnipeds, Weddell seals haul-out for reasons such as feeding, rest, avoidance of predators, and thermoregulation.

[10][6] In the first week post parturition, haul-out frequency is high and females remain hauled-out for longer periods prior to the pups starting to swim.

[7][10][6] Walruses tend to occupy both terrestrial and sea ice haul-out sites, alternating between the two depending on resource availability.

[8][11] Hauling-out is also used as a method of thermoregulation, therefore it is influenced by various environmental factors such as wind speed, temperature, and even time of day.

[8] Accounting for these environmental factors, walruses more frequently haul-out from late morning to early evening and avoid hauling-out during weather periods of intense cold or high winds.

[9] Ringed seals have a diel haul-out pattern in which they spend more time hauled-out during the night, an uncommon feature among pinnipeds.

[2][16] Frequency and duration of the behaviour is at a maxima during early afternoon when lower tides and higher air temperatures are prevalent.

[2][16] Harbour seals commonly inhabit regions susceptible to human disturbances (i.e. industries such as the fishery), a factor that has been studied and shown to alter haul-out patterns.
