The sword-billed hummingbird belongs to the genus Saber-billed Hummingbird and is the only species in this genus. The sword-billed hummingbird is the only bird in the world with a mouth longer than the rest of its body, and this long beak allows it to suck on nectar-source plants that grow long corolla. For example, the genus Mandala, the upside-down admiralty plant.
Not only are their mouths long, but their tongues are also quite long! They love nectar-source plants with large nectar content. Ability to hover in front of an upside-down Admiralty plant flower and suck nectar thirteen times per second! It looked as if it was hanging on a flower.
The long-beaked moth is known as the "four different elephants" in the insect world. It is first like a butterfly, as active during the day as a butterfly, with a long beak tube and a large antennae with a large tip; it is like a hymenoptera bee, flying in the summer and autumn to collect nectar in the hundred flowers, and emits a clear and audible buzzing sound; it is also like the South American hummingbird, which lies out at night and rarely rests, and when feeding, it is like a hummingbird, sometimes rushing between flowers, sometimes circling in front of the flowers.
In 1862, Darwin received a package from one of his friends, james, a well-known orchid expert, containing a specimen of the Great Comet Orchid from Madagascar, which he saw at a glance nearly 30 centimeters long, an astonishing flower pitch. A sensitivity to biological research convinced Darwin that there must be some kind of moth whose beak was long enough to reach into the orchid's flower distance to suck honey, and by the 1870s, other naturalists had reported on large moths in South America with a beak of about 25 cm. In 1903, forty-one years after Darwin proposed his conjecture, the malagasy beaked moth was finally reported, and its Latin name Xanthopan morganii praedicta, the subspecies suffix praedicta, also paid tribute to Darwin's conjecture in the senses.
Twenty-five thousand years ago, the first period of human society, the Stone Age, had not yet begun, when ants had lived happily for tens of millions of years, but at this juncture, a species seemed to have snapped at the ant and was born - anteaters.
The tongue of the anteater is not only interesting, but also can extend to 60 centimeters, look like a long worm, and can be flexibly retracted, and the frequency of expansion and contraction can reach 150 times / min, which is really super fast.
The "amount of food" of anteaters is very large, basically a meal can eat a pound (equivalent to 454 grams) of ants, so it is a great contribution to inhibiting ant infestation.
However, the anteaters eat regularly and have a bottom line, and do not consume ant resources without principle. Generally, after finding an ant nest, an anteater will only eat here for about 140 days, that is, about 5 months, and after the limited date, they will consciously leave here and then change to another ant nest to "eat".
