MORE YAWNING ANIMALS

This sleepy ostrich would also outrun you easily.

The Ostrich is the largest living bird species with the

fastest land speed of any bird. Their extremely long

and powerful legs allow them to run at up to 70

kilometres per hour (43mph).

The yawning arctic fox cub looks lonely but it certainly has some

brothers and sisters. Depending on food availability, arctic fox females

usually have 5–10 young but in areas where food is abundant, they

can have as many as 25 off-springs, which is the most of all the

wild living mammals.

Turtles often open their mouth wide to intimidate potential enemies but

the narrowed eyes suggest this red-eared slider is really yawning.

Originally native only to the southern United States and northern Mexico,

this turtle has become an invasive species in many other parts of the

world as a result of pet releases.

For baboons, yawning is a great opportunity to display their impressive

sharp canines. Their diet is mostly herbivorous but generally, baboons

are omnivorous animals so their powerful jaws can come handy when

preying on fish, hares, birds, other monkeys or even small antelopes

that they occasionally also eat.

The mouth of this monitor lizard seems harmless but most of the

77 currently known monitor species are carnivorous, eating eggs, smaller

reptiles, fish and birds. Monitor lizards are very intelligent animals, and

some species have even been able to count.

Apparently, squirrels know it is polite to cover their mouth when yawning.

These lively rodents are usually very small weighing just a few tens of grams

but the largest squirrel – the Alpine marmot, can be up to 73centimetres

(29in) long and weigh up to 8 kilograms (18lb).

Polar bears loves sleeping and relaxing but they do have a good

reason for that – despite living in the coldest regions on Earth, their

insulation and thermoregulation systems are so efficient that they

sometimes have to avoid strenuous physical activities not to get

overheated.

The new born otter baby yawning looks so adorable. Otters are very

playful and intelligent animals that often appear to engage in various

behaviours for sheer enjoyment, such as water sliding.

They may also find and play with small stones.
