The Hummingbird Hummingbird's heartbeat can reach over 2000 beats per minute.TheHummingbird is the world littlest bird, from the beak to the tailmeasures only 6cm (2.36inch). Is coloured with bright colours and hasan extended bill and tongue (depending on the species) to easilycollect nectar from the flowers.Apart from their size the Hummingbirds have other curiosities, Aparte de su tamaño los colibríes tienen otras curiosidades, have avery fast frequency of fluttering, they flutter 80 times in a second,allowing them to stay static in the air or to fly towards any part, tothe side, backwards, ahead. They are the only birds that can flybackwards. The Sleep of the DolphinsDolphins have different ways of sleeping. The Dolphins may sleep in different ways, depending of their needs.Floating: As a trunk in the water, thedolphin can stay afloat, leaving only outside whater the part needed tobreathe. However, this option leaves them too vulnerable to attacksfrom other dolphins or predators. Assisted by otherDolphins: The Dolphins usually turns sleeping, in couples. One of thedolphins swim while another rests in the wake left by the other,thereby allowing them to move on the surface without making musculareffort. The small dolphins should be helped by their mothers during thefirst days. The mother does not sleep, because otherwise the littledolphin could become exhausted and sink, dying from asphyxiation.HalfSleeping: The dolphins are able to close a half of his brain, leavingthe other half active, and do so alternately to one side and rest eachpart. For example, if they have the left hemisphere of the braindisconnected, the right eye can not see. The Koala The koala sleeps 20 hours a day.TheKoala is a marsupial mammal that populates Australian zones and livesin the trees. They measure between 61 and 85 cm and weight between 4and 14 kg and they are distinguished by their great dark nose and greatears. They are nocturnal animals, they only make its activities at nightand therefore they have a very developed ear and sense of smell,although we cannot say the same of its sight. But most surprising is its way of life, they sleep around 20h a day,more even than the Pale-throated Three-toed Sloth, that only sleeps18h. They make it to save energy and power to survive in conditions offood shortage.
