Individuals take turns moving to the group's protected and relatively toasty interior. Once a penguin has warmed a bit it will move to the perimeter of the group so that others can enjoy protection from the icy elements.
Emperor penguins spend the long winter on the open ice—and even breed during this harsh season. Females lay a single egg and then promptly leave it behind. They undertake an extended hunting trip that lasts some two months! Depending on the extent of the ice pack, females may need to travel some 50 miles just to reach the open ocean, where they will feed on fish, squid, and krill. At sea, emperor penguins can dive to 1, feet—deeper than any other bird—and stay under for more than 20 minutes.
Male emperors keep the newly laid eggs warm, but they do not sit on them, as many other birds do. Males stand and protect their eggs from the elements by balancing them on their feet and covering them with feathered skin known as a brood pouch.
During this two-month bout of babysitting the males eat nothing and are at the mercy of the Antarctic elements. When female penguins return to the breeding site, they bring a belly full of food that they regurgitate for the newly hatched chicks.
Meanwhile, their duty done, male emperors take to the sea in search of food for themselves. Mothers care for their young chicks and protect them with the warmth of their own brood pouches. Outside of this warm cocoon, a chick could die in just a few minutes. In December, Antarctic summer, the pack ice begins to break up and open water appears near the breeding site, just as young emperor penguins are ready to swim and fish on their own.

So how does a female penguin choose a mate and what makes one male penguin more alluring than the next guy? Although males and females look alike, the males tend to be slightly bigger and have slightly longer beaks, says Dr Dann.
A deeper voice may also help make them more distinctive amongst a colony of thousands. So it seems a successful male penguin has the moves, sounds like Issac Hayes and is slightly burly. And when mating season rolls around, male humpback whales will belt out amorous tunes to woo a female.
Some research even suggests that males will start to weave complex syntax into songs to convey more information to a potential mate. But, there are always other males ready to imitate successful song styles to win over their own crushes. Sea otters lie on their backs when they're in need of a deep doze, but their prone position also creates the perfect excuse to hold paws with their significant otter.
Sea otters will either grab on to each other, or wrap themselves up in kelp, to keep from drifting apart at sea while they rest.
Sea otters are polygynous , meaning a single male can mate with several females. This usually results in fierce competition between males to land a female. Reproduction for seahorses is a delicate dance in which males and females aim to be perfectly in sync with each other.
Studies have shown that seahorse couples will court for several hours , swimming side by side to mirror each other's movements.
The longer two partners are together, the more successful they become at breeding. After mating, the male prepares to do what very few animals, including humans, are capable of doing for their lady. Male seahorses will carry up to 1, eggs in his pouch for about 45 days , leaving the females to relax until her babies are ready to be born. Together, they must jointly defend their feeding territory from other hungry fishes, showing that teamwork helps build stronger bonds with your loved one.
