How the little ones of the seahorse are born - Curious news

Did you know that Mr. Seahorse is actually a very sweet mom?

The seahorse, this delightful little fish (scrintifico name Hippókampos, from híppos «horse "e kampe «curvature »), actually has habits that not everyone knows. In fact, the puppies of this species are born from the father and not from the mother. How? I'll explain it to you.

The female produces the eggs (and so far everything proceeds according to nature). A few days before their maturation (ready to be fertilized) the female lets herself be wooed by the male who chases her relentlessly until he is able to grab her by the tail. This gesture represents marriage. At this point, mating occurs in the opposite direction: the female lays her eggs in a ventral sac of the male and only then does the male fertilize them. This sort of pouch then becomes a "placenta" where oxygen circulates to keep the eggs alive.

Mrs Cavalluccio, who has finished her task, thus resumes her daily chores, however making a daily visit to her partner, to make sure that everything is going well and that her husband is a good mother and does not overwork too much.

After 3-4 weeks, the pains begin, that is to say real muscle spasms to allow the little ones, now perfectly developed, to get out of the bag that hosted them and thus begin their independent life.

But nature… is it or isn't it wonderful?


COLIBRI. - Family of birds (Trochilidae) which belong to the order of the Pico-Passeriformes and are more commonly known under the name of Fly Birds. In fact, several species have the size of a hornet, but some reach that of the swifts. Some authors, such as Brehm, have given them a particular order calling them Schwirrvögel "buzzers", due to the hum, similar to that of some insects, which they produce during their very rapid flight. The fly birds feed on small insects, especially beetles and diptera, frequenters of flowers, so they mainly look for their food in the flowers and since the tubular corolla flowers are those that welcome the greatest number of nectar-seeking insects, it turns out that hummingbirds they especially visit this kind of flowers. To achieve the purpose, however, a special conformation of the beak and of the tongue is necessary: ​​the first is thin and sharp, now straight, now slightly curved, sometimes as long as the head, sometimes longer, as long as the body and in some species even longer. The tongue, which has a skeleton resembling that of the woodpeckers, with the long horns of the hyoid curved over the occiput up to the forehead, is bifid and ends with a membranous expansion fitted on the sides with small hooks. The length and shape of the beak are, with that of the tongue, in relation to the length and shape of the corollas that each species visits. In this way a twofold symbiotic relationship is established between the species of insects that frequent certain forms of flowers and the hummingbirds, which seek their nourishment in these, compensating the flower by favoring its cross-fertilization. Hummingbirds are therefore pollen animals, which smear their heads with pollen, and yield it to another flower in the act in which they hover in front of them, in the guise of butterflies of the Sphinx family. This kind of activity places hummingbirds among the flying birds par excellence, able to spend most of their life in the air. Their wings are long, generally narrow and more or less clearly falcate like those of the swifts, to which they also resemble for the shape of the feet, with a very short tarsus and completely unsuitable for locomotion: the nails are acute and often long enough to allow these little birds to rest on the stems and twigs of tall trees and shrubs. Hummingbirds are among the most graceful gems of living nature, sparkling like sapphires, emeralds, rubies, topazes or amethysts: the most lively red, the color of gold, indigo and violet, blend together and contrast with black of ebony and velvet or ivory white small tufts adorn them on the head or on the sides of the throat, muffs of powder on the legs.

The hummingbirds belong exclusively to America and should indeed be considered as one of the most characteristic groups of the neotropic fauna, that is, of South America. Their resistance to cold varies with the variation of the species if the majority of these are typical of the tropical and equatorial zones in relation to the greater development of a vegetation richer in flowers, there are species that go as far as the Labrador peninsula on the Atlantic and Vancouver Island on the Pacific and others that go down to Tierra del Fuego. If many hummingbirds love the forests of Brazil and the Amazon, others rise up in the Andes almost to the limit of perpetual snow, between 4 and 5000 m. high. No species of hummingbird is stationary in the strict sense: they are migratory and passage birds or at least erratic and their migrations, in apparent relationship with the seasons, are actually linked to the succession of flowering of the preferred plants under different latitudes. They have no gregarious instincts, but are instead quarrelsome and unsatisfactory with each other.

The cup-shaped nest is usually built between vertical stems and twigs, with substances that offer some difference in detail between species and species, but in which a vegetable wool similar to cotton wool predominates alternating with more resistant stems, lichens, sporangia of ferns. The eggs are two, very white and oblong, relatively large in proportion. The incubation lasts about ten days. Babies are born blind and naked but rear quickly. Many attempts have been made to keep hummingbirds in bondage, but they have generally failed due to the difficulty of providing them with live insects in sufficient quantities.

One of the largest hummingbirds is the Patagona gigas (Vieill.), Which has the size of our swift, a beak twice as long as the head and lives on the western coast of South America. The Sword-billed, Docimastes ensiferus (Boiss.), Lives in the Andes of Ecuador has a beak as long as the body and is decorated with very bright metallic colors. The Eagle's beak (Eutoxeres aquila) has a robust and sickle-shaped beak: it does not have very bright colors and is typical of Colombia. The mountain hummingbirds (Oreotrochilus Gould) have expanded the rachids of the primary remiges the magnificent Oreotrochilus chimborazo (Delat. Et Bourc.) Lives on the mountain that gave it its name, at heights varying between 4 and 5 thousand feet. Campiloptera have large arched wings and primary remiges, with expanded rachids at the base. The Topaz (Topaza pella Linn.) Owes its name to a large spot under the throat which, under certain incidences of light, appears topaz yellow: the coxswain of the second pair are more than twice as long as the others, sickle-shaped and each bent towards the inner side so as to cross X it inhabits Guiana. The males of the Lophornis Less. they have a beautiful collar of very developed feathers, narrow and with very elegant designs. In the genus Ocreatus Gould, of Brazil, the males have the tail made like a racket, because the external coxswain are very long, with parts that become shorter and shorter until they disappear about a fifth of the extremity, then suddenly they lengthen forming a species of racket. In the genus Lesbia Less., On the other hand, the lateral coxswain are graduated and the two extremes are five times as long as the medians: Lesbia sparganura (Shaw) of Bolivia has a scarlet red upper body and an orange-red tail. I Rhamphomicrum Bp. and the Oxipogon Gould have very developed feathers in the form of a tuft on the head and in the throat. (See color plates).


Below is an article taken from Gioco & Giochi which talks about the birth of seahorses in the tanks of Gardaland Sea Life.

The miracle of life is staged at Gardaland Sea Life Aquarium where 250 young seahorses belonging to the Hyppocampus Erectus species have been born a few days ago.
Baby horses measure from a few millimeters to 1.5 centimeters, less than a 1 euro coin one of the biggest weighs only a quarter of a gram.
The 250 baby horses are already perfectly autonomous and able to swim in search of food, an activity that takes up most of the life of these creatures. The particular structure of the toothless mouth and its peculiar internal anatomical characteristics make feeding particularly difficult. In fact, they feed mainly on nauplii, larvae of small crustaceans of the artemia salina species, particularly suited to the small size of their mouth.
During the swimming phase, the seahorses keep the body in a vertical position and being equipped with a dorsal fin and poorly developed pectoral fins, they use the prehensile ring tail to anchor themselves to the substrates of the seabed. They are not skilled swimmers and in order to defend themselves they have had to develop more and more sophisticated mimicry techniques over time. Here they are then presented with wonderful and colorful liveries tending to brown with spots, stripes and skin protuberances that allow them to blend into the tropical environment of coral reefs in the midst of underwater seagrass meadows.
To make these extraordinary creatures even more particular, the small eyes that can be moved independently of each other also contribute.
In addition to the Hyppocampus Erectus, at Gardaland Sea Life Aquarium there are two other species of seahorses: Hippocampus Reidi and Hippocampus Comes.

The puffer fish and the moon - a trip for young and old

The protagonist of this short and intense story is a restless and frenetic puffer who feels inside himself, at a certain point in his existence, the need for elsewhere so with courage he faces a journey into the unknown, ready to leave everything. just to find his voice, his name, his identity. Without a precise goal, the road will be marked by encounters with different characters, each of which will leave something to the little puffer fish and unknowingly guide it in its direction. A personal but never solitary journey, to remind everyone that comparison is often the winning key to one's true essence. Conversely, Serafina, a restless little fish, embarks on her journey into the unknown. A light becomes the goal for Puffer Fish but how to reach it and, finally, find yourself and rest?

A journey that spares no emotions and puts them all on the field and crosses them, even fear, the only way to live fully. And in the encounter lies the key to rediscovery.

A story that is a metaphor of life and the search for oneself, in an ironic and light key. Sugameli's writing is caressing and immediate, able to welcome everyone and leave something in everyone, as well as the sweet and rounded images that accompany the story.

A story that teaches and remembers how everyone must have the strength and courage to face the darkness and the depths of their ocean to find the light that can illuminate, without forgetting how much every living being, however unique, always finds himself living in an interconnected network, where it is vital to share one's solitude, meeting in others.

And it is in giving ourselves that we find ourselves, and it is vital to remember it in a period like this, where interconnection calls everyone to their own responsibilities as people who live together, for the common good. A reading to be faced together with the little ones, to remember how important it is to meet again.

Since chameleons have no inner and middle ears, they may appear deaf, but they are not. In fact they have the ability to detect sound frequencies in the range of 200-600 Hz.

The chameleons they love solitude, and this is demonstrated by the refusal behavior adopted by the female when the males try to approach.

The female must give the necessary consent to allow the male to approach and consequently mate. Chameleons represented by more vivid colors have an advantage over those with more delicate coloring. Many of them are usually in solitude awaiting the arrival of the mating season.

In addition to loneliness, these fascinating reptiles they love to sleep hanging upside down and they love to climb trees very easily using their hands and tail to move from one branch to another.


The goliath frog is the largest frog in the world and the second largest amphibian after the salamander. It measures 34 centimeters in size and weighs up to 3.3 kilograms.

Although this particular amphibian is still under study, the researchers were able to analyze the reproductive behaviors of the frog. The curiosity concerns its ability to build the nest for their eggs. Researchers have discovered a strange sight along a 400-meter stretch of the Mpoula River in Western Cameroon: curious pools completely cleared of gravel, leaves and other debris. Some were empty, others containing lots of tadpoles. A total of 22 potential nests were found, 14 of which even contained up to 3000 eggs each. This large frog is characterized by a high and unusual parental care. In fact, during a night shoot with an infrared camera, a parent was found monitoring the young until dawn, protecting them from potential predators. It is the largest males who take care of digging these one meter wide pits, they move heavy debris, up to two thirds of their own body, and using excavated materials they are able to build the walls of the artificial ponds.

Researchers argue that possibly nest building ability and unusual parental care are the causes of the goliath frog's large size: the larger the frog, the faster the nest building and the protection afforded to tadpoles at night. .


The video, which acts as a “mini-documentary”, goes very well with the text. Congratulations on the article, Mattia!

Fascinating article, I had no idea that such a big frog could exist!

Incredible article, how many things you discover!

This new blog has aroused a lot of curiosity within me.
The more I read your articles the more I am amazed. How many things escape man ..
I realize that many aspects are not known at all and often little attention is paid to what could turn out to be a real surprise. There
nature is full of mysteries, penetrated by occult forces, so it is often not possible to get there even with the imagination and researches like these serve as a means to learn about them!
We must always measure ourselves against ourselves and discover new horizons, thus enriching our points of view and therefore our knowledge.
The earth is not occupied only by humans but by many many species. I was not aware of such large frogs. Who knows if sooner or later I'll be able to see one live! I was impressed!

I didn't think there could be a frog of this size, wow.

7 curious news that seem fake but are actually real

Although we are usually used to hearing about the fake news problem, that is news disclosed as true which then turn out to be absolutely false, today we want to play down by showing that sometimes - more rarely - the reverse is also true. If we told you in fact that a single cornflakes cereal sold for over a thousand dollars, would you believe it? Probably not, yet it is exactly the truth! We have collected below a small gallery of apparently false news which are actually real.

NB: you will find links to learn more at the end of the article.

1. Frogs use their big eyes to swallow.

Have you ever noticed that frogs close their eyes when they swallow food? This is because the muscles in the eyelids and those around the eyes are contracted to push food down the throat.

2. One cornflakes sold for $ 1,350.

Melissa and Emily McIntire, two sisters from Virginia, found a cereal that was perfectly shaped like Illinois and sold it on Ebay for $ 1,350.

3. Spain is one of the few countries to have an anthem without words.

Along with the anthem of San Marino, Kosovo and Bosnia Herzegovina, the Spanish Marcha Real does not have a text.

4. The characters on the cereal boxes always look down to intercept the eyes of the children.

Have you ever noticed that mascots on cereals often look down? This happens because, according to many researches (link at the end of the page), the aim is to intercept the eyes of the little ones who pass in the lane.

5. A woman participated in an expedition to find. herself.

In 2012, an Asian woman was traveling to Iceland when she joined a group that was looking for a missing woman. For several hours the search went on, until the woman realized that she matched the description released by the tour guides.

6. There are aphids that are born already pregnant.

Females of some aphid species are able to give birth to other females without ever having met a male.

7. There is a caterpillar that "disguises" itself as bird droppings to avoid predators.

The caterpillar of the giant swallowtail butterfly has taken disguise to another level: its appearance makes it look like bird droppings, making it virtually unappetizing for predators.
