Product Information

Amongst our vast selection of collectable teddy bears, you will find the world renowed Steiff Bears from Germany, Charlie Bears from Cornwall (we are a Paw Store), Merrythought Bears from Shropshire as well as Clemens Bears from Germany, to name but a few. For those wanting a unique one of a kind bear we offer a fabulous selection of Artist Bears from around the world, including beautiful bears from local Bear Artists based in the South West and Cornwall. We also specialise in Antique and Vintage Bears that have long been retired and are hard to find with our selection changing weekly.

PMID 8744762.As other bears head out onto the ice and begin to gorge on seals, those females rest in the warm, dark dens, where they give birth in the winter and emerge with their cubs in the spring. They eat as much as they can in the spring so they can survive the summer shortfall and wait for sea ice to form anew the following fall, as the cycle begins again. Cavalieri, D. J., Parkinson, C.

When the mating season ends, the female will build up more fat reserves to sustain both herself and her young. Sometime between August and October, the female constructs and enters a maternity den for winter. Depending on the area, maternity dens can be found in sea ice just off the coastline or further inland and may be dug underneath snow, earth or a combination of both. [122] The inside of these shelters can be around 1.5m (4.9ft) wide with a ceiling height of 1.2m (3.9ft) while the entrance may be 2.1m (6.9ft) long and 1.2m (3.9ft) wide. The temperature of a den can be much higher than the outside. [123] Females hibernate and give birth to their cubs in the dens. [124] Hibernating bears fast and internally recycle bodily waste. Polar bears experience delayed implantation and the fertilized embryo does not start development until the fall, between mid-September and mid-October. [125] With delayed implantation, gestation in the species lasts seven to nine months but actual pregnancy is only two months. [126] Aars, J. et al.

Polar bears may travel areas as small as 3,500km 2 (1,400sqmi) to as large as 38,000km 2 (15,000sqmi) in a year, while drifting ice allows them to move further. [70] Depending on ice conditions, a bear can travel an average of 12km (7.5mi) per day. [71] These movements are powered by their energy-rich diet. [46] Polar bears move by walking and galloping and do not trot. [72] Walking bears tilt their front paws towards each other. [39] They can run at estimated speeds of up to 40km/h (25mph) [73] but typically move at around 5.5km/h (3.4mph). [74] Polar bears are also capable swimmers and can swim at up to 6km/h (3.7mph). [75] One study found they can swim for an average of 3.4 days at a time and travel an average of 154.2km (95.8mi). [76] They can dive for as long as three minutes. [77] When swimming, the broad front paws do the paddling, while the hind legs play a role in steering and diving. [10] [39] Mother bear and cubs sleeping In 2015, the IUCN Red List categorized the polar bear as vulnerable due to a "decline in area of occupancy, extent of occurrence and/or quality of habitat". It estimated the total population to be between 22,000 to 31,000, and the current population trend is unknown. Threats to polar bear populations include climate change, pollution and energy development. [2] a b c Slater, G. J.; Figueirido, B.; Louis, L.; Yang, P.; Van Valkenburgh, B. (2010).
