Currently scientists are still plenty of questions about the evolutionary history of penguins. Until now, the only fossils exist in New Zealand land about 62 million years ago, said spending is Waimaru oldest penguins. Their body structure is quite similar to penguin species now they are very short wings and fly. The only other time such a thing has not really Waimaru life in the aquatic environment and adapted to diving to catch prey.

You often see the shape of penguins in the white part of the abdomen and covers dark part behind. We use short wings for flippers when submerged under water. The front legs are used to move on the ground to look pretty waddling penguin species and especially taking advantage of the belly plate to slip on the snow front every time you want to go with more speed.

In the world there are about 18 different species of penguins. However, of which 13 species have declining populations due to climate, habitat and lack of responsibility in the preservation of the human species. Even more alarming, there are five species are listed as endangered by the Association International Union for Conservation of Nature statistics include White-flippered, Erect-crested, Galapagos, Humboldt and Yellow eyed.

Penguins live species populations, with high social, always focused in herds. Each population can be up to tens of thousands of children. Despite the large number and difficult to control like this, but every parent penguin couple, we are able to identify and look after her children through a special hearing.

Depending on the different species of penguins, bird life of around 15-20 years. In it, we spend 75% of their life living in sea water environment. For penguin species, our tear ducts rather special, can filter the excess salt from the blood. Salt is excreted through nasal liquid form. So we can drink seawater and live in this environment with ease.

The male penguin will assume the role of incubation for about two months while the children will go foraging at sea. During incubation, father penguins will stop everyday activities, just focus on the protection of eggs. We use the stored fat in the body to maintain strength. Typically, the male penguin will reduce lost half their body weight following this process. At the end of the period of two months, male and female penguin will circulate role to ensure health for themselves, review journal

Social community penguins, they communicate and exchange information with each other through body language using its head and flippers. In particular, for the penguin species, the researchers are not surprised and amazed feelings in relationship their mother. When children lost their baby or child dies, it will seek to "kidnapped" children of farming families bring. The reason most logical explanation is probably because the mother can not stand the pain of losing children and to deceive ourselves.

Penguins can swim about 15 miles per hour far exceed the international Olympic gold medalist Michael Phelps swimming to 4.7 miles per hour. They can dive underwater to record about 20 minutes. Usually small penguins dive deep, averaging only about 1-2 minutes to hold your breath looking for prey. However for larger species, they can dive to depths required in their abilities, which must mention the emperor penguins to dive to 565m record.

No coincidence that penguins have a special coat in front of white abdomen and in the back is dark. It is a disguised way of penguin prey before. Black to hide behind when diving into the dark waters, white to hide on the ice or the snow cold regions.

Penguins have no external genitalia so with the naked eye can not distinguish what is where children are males. Only when a new chromosome test to identify their gender. Especially in populations of penguins, also appeared homosexuality. Wildlife park located in Bremerhaven, northern Germany, two male penguins were hatching an egg together, treat each other as couples.

The Lava Heron has evolved to adapt to its environment through its colouring.

The Lava Herons colouring enables it to blend in with its environment and therefore hide from predators. The adults can be very dark and difficult to spot against the lava.

The Lava Heron stalks small crabs and fish slowly before quickly spearing and eating them.

The adult Lava Heron is slate-grey, which helps it blend in with the hardened lava. The back feathers typically have a silvery sheen and it has a short crest on its head. The feeding behaviour of the Lava Heron is quite impressive, it can catch small crabs at a rate of 2-3 crabs a minute.

Lava Herons are monogamous (only breed with one mate at a time) for the breeding season and engage in elaborate courtship displays. They can breed year-round, though typically from September to March and can mate up to three times a year.

Male Lava Herons obtain bright breeding colours on legs and beaks and some like the Great and Snowy Egrets develop aigrettes, which are spectacular head, neck and scapular plumes. When breeding, the heron has a black beak and bright orange legs, but they fade to grey after the breeding season.

After they formed pairs, females build platform nests of sticks in trees, shrubs or bushes near water while the males gather the necessary materials. Up to 10 eggs are laid and both incubate and the hatching is asynchronous.
