Are polar bears the most incredible mothers? (obviously excluding our mums... mum you're definitely the best!!)
Now we've set that right - this is why we think polar bears are the best!
After mating out on the ice in spring (that's April to June) the males will hang around for a day or two then head off in search of food or another female (try to resist the easy jokes here!). What is incredible is that any fertilised eggs will not become fully implanted until autumn and only then if the female has fattened up enough to sustain a pregnancy.
When winter starts to set in she will then dig her den in the snow, ready to give birth hidden away from prying eyes (and mouths).
Most polar bears are born in December and are either twins or triplets. They will live in that warm den, protected from the elements until spring arrives. Mum won't eat or drink anything in that time, she is totally reliant on her fat stores.
Emerging from the den when the cubs are strong enough is the first step into a dangerous world for the new family.
The mum will nurse her cubs for up to 30 months, teaching them how to sniff out and hunt seals and protecting them from marauding males who will consider a cub to be an easy meal.
When the cubs are strong enough they leave mum and head off leaving her to start the process all over again. She may go through this process 4 or 5 times in her 20 to 25 year lifespan.
Surely a candidate for Mum of the Year??
(should we cover why emperor penguins are the best dads next?)
