What is cuttlefish?

Every canary owner probably knows about the "cuttlefish bone" that is taken from cuttlefish. This bone is given to canaries and other tame birds so that they can sharpen their beaks on it. But other than that, we know next to nothing about the cuttlefish. Cuttlefish is not a fish, but a mollusk. It belongs to the order of mollusks, which are called "cephalopods". They are called so because their tentacles, or legs, are located around the mouth. The octopus also belongs to this group of molluscs.

The cuttlefish is a rather curious creature. It moves softly and silently through the water, using a series of fins that attach to its shield-like body. Sometimes, while moving, she raises the first pair of her tentacles. When the cuttlefish approaches its prey and approaches it within attack range, it suddenly ejects a pair of long tentacles from the cavities located in its wide head behind its bulging eyes. She grabs her prey with the help of suction cups at the ends of these tentacles and pulls her towards her at such a distance that two more pairs of shorter tentacles, which also have suckers and are located around the head, come into play.

The cuttlefish also has a beak that resembles a parrot's beak, and if the victim suddenly has a hard shell, she simply breaks the shell with this beak. If the cuttlefish decides to flee from someone, then it moves away very quickly. She does this by a sharp ejection of water through a pipe called a "siphon". Sometimes, when she wants to confuse an opponent, she muddies the water with a cloud of an inky liquid called "sepia".

By the way, this same inky sepia is used by man: a rich brown pigment or dye is made from it. Cuttlefish meat can be eaten when dried, and the bone, which is a bone-like shell under the cuttlefish skin, is ground into a powder and used in the manufacture of some toothpastes.

Where are most of the world's soccer balls made?

80% of all soccer balls in the world are produced in Pakistan, with three-quarters of them in the city of Sialkot. A significant number of these balls are made using child labor, although this problem has been addressed in recent years.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The Amazon is drying up 07.10.2006

In the autumn of 2005, hydrologists noted a record low water level in the Amazon in northeastern Peru, near the city of Iquitos.

Compared to the usual average level, the water dropped by about 3 meters. According to Fernando Rodriguez of the Amazon Research Institute in Peru, this is a consequence of the destruction of forests along the banks of the great river and its tributaries.

More than 10 million hectares have already been cut down, as a result, the amount of rainfall has decreased, not only in this region, but also in North America, all the way to Texas. The rate of deforestation is only increasing.
