Curiosities of the Animal Kingdom


The strongest, the oldest, the loudest, the most poisonous, etc.

In this section, we present several curiosities about the animal kingdom, both in Brazil and in the world.

Older

Animals passed from sea to land 414 million years ago. The world's first land animals include two types of centipedes and a small spider found among plant debris.

Noisier

The noisiest of land animals is howler monkeys in Central and South America. Males have a bony structure at the top of the trachea that allows sound to reverberate. Their frightening screams have been described as a mix of dog bark and donkey bray, magnified a thousand times, their screams can be heard up to five kilometers away.

Stronger

In proportion to their size, the strongest animals are giant beetles, found mainly in the tropics. Tests on the rhinoceros beetle have shown that it can support 850 times its own weight on its back. For comparison, a man can lift (with a support aid) only 17 times his own weight.

Stronger bite

A 2 m long brown shark can exert a force of 60 kg between its jaws, equivalent to a pressure of t / cm2 on the tips of the teeth. Although they have not measured the bites of larger sharks such as the white shark, it should be even stronger.

Keener smell

Nature's most keen sense of smell is that of the male emperor moth who, according to experiments done in Germany in 1961, can detect the sexual substance produced by the virgin female at a distance of 11 km, against the wind. The receptors located on male antennas are so sensitive that they can detect a single molecule of substance.

More poisonous

The bright little frogs of Central and South America secrete some of the most deadly biological toxins known. The species is so dangerous that scientists need to wear thick gloves to manipulate it if they have cuts or scratches on their hands.

MAMMALS

BiggerThe largest mammal on the planet is the blue whale.

HeaviestA female whale weighing 190 t and measuring 27.6 m in length was caught in the South Atlantic.

Longer
The longest specimen ever recorded was a 33.58-foot female whale that ran aground on Grytvi Beach, South Georgia, in 1909.

Largest terrestrial
On average, male elephants reach a height of 3 to 3.7 and weigh 4 to 7 t. The largest specimen ever recorded was a male shot dead in Macusso, Angola. Lying on its side, the elephant measured 4.16 m in a line projected from the highest point of the back to the base of the front, indicating a height of 3.96 m when standing. Its weight was estimated at over 12.24 t.

IN BRAZIL

The largest Brazilian land mammal, the tapir or tapir, measures 2.01 m in length and weighs about 250 kg, reaching 1.08 m in height.

Greater Marine
The largest toothed mammal is the sperm whale, its inner jaw measures approximately 5 m. With a length of 25.6 m.

HigherThe tallest living animal is the giraffe, found only in the dry savannah and semi-desert areas of Africa, south of the Sahara.

Minors
The bat has a wingspan of about 16 cm and a length of between 2.9 and 3.3 m, weighing from 1.7 to 2.0 g. This species is found only in about 21 Kwae Roi River limestone caves in southwest Thailand.

Faster marine
The orca whale reaches a speed of 55.5 km / h, with about 6.1 to 7.6 m in length.

SlowerThree-finger laziness develops an average speed of 1.8 to 2.4 m / min (0.1-0.6 Km / h). However, over trees, it can “accelerate” to 4.6 m / min (0.27 km / h).

More sleepySome armadillos and sloths spend up to 80% of their lives sleeping or dozing off.

Largest LitterThe largest number of pups of a wild animal in a single litter was 31 in the case of a tenrec found in Madagascar.

CARNIVORES

Largest terrestrialThe largest terrestrial carnivore is the polar bear, whose males weigh 400 to 600 kg and measure 2.4 to 2.6 m from snout to tail.

Heaviest
A so-called 907 kg polar bear and about 3.5 m from the muzzle to the tail was shot east of Kotzebue, Alaska, USA.

Lighter
The dwarf ferret has a body of 11 to 26 cm, a tail of 1.3 to 8.7 cm and weighs from 30 to 200 g, and the smallest individuals are females that inhabit Siberia and the Alps.

In Brazil
The smallest Brazilian carnivore is the Amazonian ferret, also called a ferret, measuring 26 cm on average.
