Lion | The king who predominates in much of Africa | (Animals of the World) | Predators | - Duration: 13:31.

you can not talk about predators without bringing up what may be the best distinguished,

I would personally dare to say that it is one of the best known animals and one

of which people have in mind, lions are one of the most popular predators

that exist and no matter what country you are from, the vast majority of the population knows about

its existence, besides being one of the most studied wildlife animals.

Many of the lions live in Africa, in their sub-Saharan region, so in

the northern region, where we can find the deserts of the continent, do not present

lions naturally, they are distributed in plains or savannas with great coverage of

pastures, avoiding moist forests; but what few people know is that also

in Asia there are lions, where they form their own subspecies, they live in bushes and in

small portions of forests. they are mammals of the panthera genus, that is felines that

rugen, where 5 African and one Asian subspecies are known, differentiated by their region

geographic, but many researchers debate about the validity of the 5 African subspecies,

leaving the Asian subspecies immovable. the lions are felines with short fur, with

a size of 1 meter 70 up to 3 meters long from the head to the base of the tail,

with a tail of 70 to 100 centimeters, and a weight of 150 to 220 kilograms, but this depends

of the subspecies and if it is male or female, which makes them the second largest feline

of the world, after the tigers. apart from the size, being the biggest males

that the females, those of the masculine gender when mature, grow a hair that covers them

the caudal part of the head from the top descending to the chin leaving the

discovered the face of the male, where this mane can be black to blond.

its fur may vary according to its region, straw color, yellowish red, orange,

gray to dark brown, taking into account that there may also be individuals, whites,

albinos and with melanism, but the latter are rare mutations in the specimens.

they are felines with robust bodies for their muscles, in addition to having a very long torso, their

ears are rounded, their necks reduced and thick to prevent a fatal blow

the impact of an animal that is defending itself, with square snouts endowed by the typical

teeth of a carnivorous mammal, exposing 4 very developed fangs at least

of 7 cm. They are also very muscular in proportion to their legs, in each phalanx

is equipped with claws, 5 digits on the front legs, where one of them is a

spur plus its nails are retractable to keep them sharp for the moment

that you have to use them, while the fingers of the hind limbs are

exposed all the time, because with its four extensions they serve to have grip

when they chase a prey. despite their reputation, they are enough animals

loafers, spend 20 hours a day resting while lying down, resting from the

sun, but can be active at any time of the day, this depends properly

of the habits of the herbivores, other carnivores in the area and the weather that is

present at that time, but as much of the time is hot, its greatest activity

It is presented at nightfall. of all felines in their natural state, is the one that has

greater social interaction with their peers, being the only ones who form groups and live

all the time in him, where this social group is called pride, the proud

they can vary in numbers, they can be 2, which are usually 2 young males, of

2 to 3 years, which are growing and looking for females, up to 40 but on average they are

15 congenres, composed of a male, a group of females, where one of them is the

leader, some juvenile lion and the puppies. the females are the ones who decide the territory,

that normally belongs to the mother and it is the males that are allowed

enter these. the females are very jealous and do not allow another to enter the group anymore

that under very marked conditions, these are born of some pride female or

some member dies, which is why a large part of its associates are genetically related

as family members, on the other hand males are very dominant and aggressive with their companions,

do not let any male approach them by attacking them, and the male offspring

He expels when they reach a certain age, seeing them as a competition to his group. the females

usually they are much calmer and rarely quarrel with each other, but conflicts

of males, they are capable of critically damaging or killing others, not only by defending themselves

himself, but he runs the risk of losing his pride, as much as his social group as

its hierarchy and its territory, which mark with urine in the vegetation, which can be

from 20 to 400 square kilometers. While the group is calm, it can be

see doing a kind of greeting where the congeners can be seen rubbing

heads with tails rolled up in the air, having the ability to recognize individuals

and interact with other lions to benefit their own survival. for communicating

each resort to roars, which can be presented in chorus as the howls of the

Wolves. so they present an acoustic, chemical communication and through contact,

creating a very close bond that they implement very well during their time of farming.

they are strict carnivores and usually hunt in groups, the females are the ones that have the

task of catching the prey and one is the one that causes the death of its prey. with

often look for large herbivores, which can exceed their volume, where they pursue

a prey trying to knock it down holding them with their claws, taking turns between each

to avoid a mortal wound of it and to exhaust it, to later bite the neck and to tear

the important blood vessels that nourish the brain and oxygenate it, the success of

capture depends largely on the number of specimens, while the nomadic lions

or the small groups hunt in the same way but with a much smaller triumph. People say that

the males do not marry directly, because most of the weights would identify him,

this because of its mane that stands out from the environment and that is precisely the function of its mane.

Due to its social structure, its reproduction is composed of the harem, the lionesses are

polyester, that is, they can enter into heat at any time of the year, presenting

a greater peak during rainy seasons, but a very interesting fact is that for every

gestation the male made several mounts in the female, copulating up to 3000 times

each puppy, mating approximately 2 times per hour for a period of 4

days, so it could be theorized that their fertility is very low, females normally

they synchronize at the same times of the year. If fertilization occurred, it will proceed

to gestation that has a period of 3 months and 15 days, where a litter will give birth

from 2 to 6 puppies, that are born blind, deaf, unable to walk and with a weight of 1 to

2 kilograms, so they take care of them with greater scrutiny at this time, not only the mother

if not the other partners, the eyes open them at 11 days, they will walk at 15 and

They can run at 30 days, where normally the mother keeps the young protected.

in one place for 8 weeks, where it feeds them for 7 to 10 months, plus other mothers can

act as nurses, and then instruct them in the art of hunting, while the

father has the indirect purpose of taking care of them with his presence where the greatest danger of

the offspring is that the male dies or is replaced by another, because this new patriarch

will kill all the offspring of their new pride, this so that their genes are transmitted and

prevail, because not only the offspring of its competitor was eliminated, but that

the females will come back in heat 3 weeks later, but many mothers defend their

you grow up to the point of losing your life on the part of the new male. If everything goes in order,

the puppies will grow and perfect their hunting techniques, where the males when reaching

the 2 years and begin to grow their hair are expelled, while the females

remain in the same group unless they are in need of moving to another, arriving

to sexual maturity at 4 years and males at 5, where they are already fully competent

to attract other females and compete with other rivals. your average life in the wild

it is very different depending on the sexes, while the females live about 15 years, the males

they do not exceed 10, this for their life and they are usually killed by some much

younger, due to the injuries they cause, do not have many predators, in fact

one that has been seen that hunts depending on the context are spotted hyenas, hence

they are the biggest link in the food chain, but if we remove the deteriorating factors

his life expectancy as is captivity, a lion, regardless of sex

an average life of 30 years. its state of conservation is stipulated in

vulnerable in general, emancipated to its subspecies, but this depends on the region since in

some countries are extinct or their population is very deteriorated, human factors

they focus on the excessive hunting of them because of the fear that they infuse, that to tell the truth

it is slightly justified, because they are animals that marry people or kill their cattle.

another factor is a disease called feline immune deficiency syndrome, which is very

present in the population of this carnivore, the virus itself is not lethal, but by immunosuppression

the infected is left at the mercy of secondary infections that end up taking the life of the

individual, a disease that is sexually transmitted between felines. and maybe the factor

more important is the genetic bottleneck they are presenting, that many specimens

have had a low fertility rate, because males with more sexual vigor and

who have a higher amount of testosterone production, their ability to produce

of spermatozoa is diminished, where these specimens are the ones that tend to monopolize

the proud ones to reverse its low population, which

It has been estimated that little more than half has disappeared in the last 20 years,

can act in several ways, the first is to create reserves, create ways where

Lions do not get into the farms and do not interact with people to prevent attacks

of these felines, for this it is necessary to take care of their habitat, conserving their territory and that

have an optimal amount of prey. to fight diseases, it must be maintained

a healthy population in captivity, and that these specimens when breeding, a population

begin to introduce into their habitat, where it has been studied that there is a low rate of

morbidity of infections. and the one that very few people will like is hunting

controlled, that is, to promote through studies that specimens are the most feasible

that are used for people to marry them, so they understand better I'll

to try to be as clear as possible, a reproducing animal inherits its DNA from its offspring,

but this does not always mean that it is suitable for the species, although the lions

they inherit a genetics that triggers greater vigor and strength, their fertility is very compromised,

but these by this feature kill other lions, which maybe less fierce have

greater fertility, making his offspring present this same problem and growing

more and more for the natural inbreeding they present, to the point that it can be

the case that lions are infertile, digging with their own species, but if you count

with a predator that focuses on these males, which are usually the ones that people are looking for

that hunt lions as trophies, allow less strong lions to have greater

possibilities of leaving your genes in the following, opening the threshold of the bottleneck and

even if some lions die, this factor would not extinguish the species, guaranteeing its

remained, maybe I'm not so clear about what I'll do in the future, a video talking

of this controversial topic. one of the best-known animals and considered

the king of Africa, where many people, facilities, places and countries benefit

of their presence, because they are very attractive to people, so it would be a zafarí

without lions, one of the best-known predators in the world, that's the lion.
