The Hummingbird

Hummingbird's heartbeat can reach over 2000 beats per minute.

The
Hummingbird is the world littlest bird, from the beak to the tail
measures only 6cm (2.36inch). Is coloured with bright colours and has
an extended bill and tongue (depending on the species) to easily
collect nectar from the flowers.

Apart from their size the Hummingbirds have other curiosities,

Aparte de su tamaño los colibríes tienen otras curiosidades, have a
very 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, to
the side, backwards, ahead. They are the only birds that can fly
backwards.
The Sleep of the Dolphins

Dolphins have different ways of sleeping.

The Dolphins may sleep in different ways, depending of their needs.

Floating: As a trunk in the water, the
dolphin can stay afloat, leaving only outside whater the part needed to
breathe. However, this option leaves them too vulnerable to attacks
from other dolphins or predators.

Assisted by other
Dolphins: The Dolphins usually turns sleeping, in couples. One of the
dolphins swim while another rests in the wake left by the other,
thereby allowing them to move on the surface without making muscular
effort. The small dolphins should be helped by their mothers during the
first days. The mother does not sleep, because otherwise the little
dolphin could become exhausted and sink, dying from asphyxiation.

Half
Sleeping: The dolphins are able to close a half of his brain, leaving
the other half active, and do so alternately to one side and rest each
part. For example, if they have the left hemisphere of the brain
disconnected, the right eye can not see.

The Koala

The koala sleeps 20 hours a day.

The
Koala is a marsupial mammal that populates Australian zones and lives
in the trees. They measure between 61 and 85 cm and weight between 4
and 14 kg and they are distinguished by their great dark nose and great
ears.

They are nocturnal animals, they only make its activities at night
and 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 sleeps
18h. They make it to save energy and power to survive in conditions of
food shortage.
