There is a very important genetic condition in some species, this is centered, that even
belonging to the same genetic group, the sexes can present visual differences
very marked, this in order to attract the opposite sex or adapt to the environment
by means of different qualities, this event is known as sexual dimorphism,
that can go from the presidency of some character, like the growth of hair in some
part or the externalization of the sexual organs, reaching the point that the
changes are so marked that they look like 2 completely different species; This can
create an interesting ruble, which are the 9 animals with the most sexual dimorphisms
marked. a big difference that there may be between
the sexes of the species of some herbivores, is the presence of antlers, this can be seen
as a generality, that is, to think that only the males present them but not; in
some species, both presents them. but one fact is that the wapitis, who live at
North of the American continent, they have very visible features that help identify them
distance. The first thing is that the males are the ones that present
antlers, consisting of a main branch that develops secondary tips according to
they are growing, so the bigger this age is, the more impressive
is this extension, which helps attract females and as a method to defend themselves
and compete with other males for territory or for attracting the opposite sex, but not
they present the whole year, since after the breeding season, the antlers are moved,
which is governed by testosterone levels. but another difference they have is that they are
the males that develop a greater growth of hair on the head and neck, the
which is called mane, has a darker color than the hue of its other
hair and this is present all year. although the size and weight are also
older in males, the presence of antlers and their mane make them one of the animals
with significant differences before the opposite sex.
This is the animal with the best known difference of the animal kingdom. the lions have the dimorphism
sexier and is very easy to remember, males are those with a mane,
this in order to attract other females to your group, also if it is luxuriant and
of a very dark color that contrasts with the color of its fur, it becomes a great
advantage over other congeners of the same sex and have a much bigger pride.
This mane, apart from having a sexual function, helps them as an extra protection
when they fight against others, because the hair serves as a kind of mattress
helping to make it harder for the claws and fangs to penetrate the skin of the neck
in a conflict, it is still not infallible, but it is useful for other males to determine
in the distance the aptitudes of this, so it is also a signal that helps them
to prevent unnecessary conflicts. although the previous post also has
a mane, that of the lion is the most significant and known by the people for what is the reason
who is in a major position.
primates have significant differences, in some species it is much more marked
that in others, for example it is very easy to sex the gorillas, since the males have a
greater development and size, but it's nothing compared to orangutans, being
the primates with the most visible. males tend to be of a larger size, but what
which stands out from adults is that they develop a hypertrophy of the cheeks, so much so that
their faces are modified to the point of being apart from another species compared to females,
which grow by the pads on the sides of the face, known as bridles,
and when presenting this more abundant muscle and fat, the muscles of the face also
they increase by it and are supported by a sagittal crest in the much larger skull
than the females. this tells them that their face takes on an appearance
of a plate and much coarser features, helping them that the bigger and bigger this
more females will have and their territory will be much greater. what guarantees you a greater
probability that their genes are processed with a higher incidence.
so spectacular is their difference, orangutans have one of the most colorful
sexual dimorphisms. already at this point we enter the animals that
their differences are so large and marked that one might think that they are 2 species
completely different and for them we have the peacock, a bird that the males are so
showy and greatly overshadow the females, their plumage of a very bright metallic color
it is adorned with more intensity by the feathers of its tail.
This ornament is composed of long feathers, which at the tips of the beards form
one circle and in the center they have another one that is given the name ocelos, this
It helps them to be much more attractive, thus attracting the females, but also
predators, so they also use them to scare them when deploying their
caudal plumage and appear to be much larger, than the feathers to appear to be eyes
get scared or instead of attacking his body, causing a lethal injury, they focus
in the plumage, causing this attack to allow him to flee.
Due to its color and especially the rear feathers, they are one of those species that
to be easy to sex, their differences are so wide that people can confuse them
with another species. This is a bird that lives naturally in
Asia, especially in the countries of China, Korea and Japan, the sexual dimorphism in
the ducks is somewhat contrasting, some are very colorful and others are very similar,
but what concerns us in this video, is the mandarin duck which presents the greatest
change, the females are dull and brown, but the male is the one who counts
with a very bright plumage, to start its orange colors, the chest of color
white and a red peak, make them stand out.
unlike the peacock that presents a monotony in its colors, in these is more
diffuse, presented a half moon on the face, a purple portion above the feathers
white and if it was not enough, a portion of the feathers are bent upwards giving them a
unique appearance, called candles, but as the number 9, they move their
feathers after the breeding season and have a more dull color, so
his colors serve him as sexual attraction. being of such a different color one could
confuse with another species, being one of the most striking for this condition, plus
It is a symbol of love and fidelity for some Asian cultures.
so far most of the differences are focused on vertebrates, but some incest
they also present them and the most attractive of all are the deer insects, many
they know these by their large jaws protruding from their heads, to the point
to be able to have the same size as your body, but what few know is that only the males
have such a development, while the females are of a size, which we could call
normal in arthropods, but their jaws are more powerful than that of males.
like the other exponents of this video, it is used to fight against others
males, to demonstrate their superiority before the courtship period.
this is the biggest difference that mammals can have in terms of sexual dimorphism,
one of the largest pinnipeds, but it's the males that reach a gigantic size
compared to females, weighing 10 times more than them, turning them
an animal with the most disparate size between the sexes and perhaps the mammal with the largest
in this condition, the elephant seals. but the biggest difference is the growth
nasal, that is, the males develop a proboscis that helps them attract others
females, but it is also the region that receives the most damage when they fight between
of the same sex coming to tear portions. this horn allows them to make a call
stronger and more powerful, in addition to presenting a harem as a form of reproduction and that
intercourse takes place in the water, helps them to rebore the water they exhale through the cavities
that you have, because you can not drink seawater and you need a way to get it
so as not to become dehydrated by spending much more time in the ocean while looking for partners
and they reproduce. being the male the one with the largest
Sexual dimorphism is essential in any list that touches this topic.
So far we have seen that males dominate this topic, but it is
focused on mating and courtship, but what happens with females. good you are
they also have specimens that stand out and one of them are spiders, but not any
Arachnid has a sexual dimorphism as marked as black widows.
are the females that have a larger size than the male, have a bright black
very particular and on the back of the opisthosoma have such particular marks,
depending on the species these can be of different forms, being the most common and
known the North American black widows which present a pattern very similar to
a sand clock. while the male is brownish brown, much less gleaming,
half the size of the female. besides, the opisthosoma is much larger and round;
being the female sex much more poisonous than the male, this because being more striking,
they require more protection. and last but not least, some species after
to reproduce they eat the male, apart from those who are not eaten his life is much more
short. being a well-known species and it is important
recognize them since it can save someone's life if they are detected, being one of the
most distinctive animals
the vast majority of the differences focus on reproduction, but this specimen,
when you see them you will think that they are not the same species, in fact they are so different and their habits
so different that in very few occasions males are seen. the triple sea demon
wart, is the species with the biggest differences between males and females, being the last
those that are commonly known. to begin with, they are fish that inhabit the depressions of
oceans at 2000 meters depth, and the females have a luminescent organ
on its head to attract its prey, it presents enormous rows of sharp teeth,
not being very different from other fish in your family.
but the males are much smaller, their digestive systems are partially
atrophied, so they are in need to parasitize the females by looking close
of the cloaca to feed themselves and the only function they have is to provide
sperm. for being so different, and with his habits
where the male becomes a parasite to survive, the triple sea demons
wart, are the animals with the widest sexual diformism that can be on the planet,
so much that if they are seen separately you would never think that they are of the same species.
