Most animals die without food and staying still. But an animal called the om, or Proteus anguinus, can remain motionless for years, but it still survives. Scientific teams from the UK and Hungary found that the cave, which lives in caves in Bosnia and Herzegovina, is less than 32 feet (10 meters) long and can remain inplace for 2,569 consecutive days, or more than seven years.
The study, published recently in the Journal of Zoology, said specific specimens have not moved for seven years, but they are still alive. The cave (also known as the blind dragonfly, the name: Proteus anguinus) is an amphibian. It perches in the groundwater veins of the limestone cave in the Dinari Alps, spread from the Isonzo River basin near Diriaste, Italy, through southern Slovenia and southwestern Croatia, as far as Hesegovina. This species is also the only species under the cave. In addition, it is the only creature in Europe belonging to the cave section, and the only cave-in-the-ridge animal in Europe.
The cave has a snake-like body, usually 20 to 30 cm in length, but some individuals can reach 40 cm in length. Its torso is cylindrical and roughly identical in thickness. On the lines of myomere, there are uniformed wrinkles that divide the torso into sections. Its tail is relatively short, flat, and surrounded by a thin fin;
The most notable feature of this animal is the adjustments made to adapt to the dark life in the cave. For example, the degenerative eye of the cave is hidden under the skin, making it invisible, but its other senses, especially the sense of smell and hearing, become more acute to compensate for visual deficiencies. In addition, the skin of the cave is lack ingested in the pigment, all except for the life-long presence of the three outer swashes are bright red, the other parts are white (e.g. in daylight for several months, eyes and skin first gray white, after all turned black). In addition to the breeding period, the other periods of the cave’s life are completely spent in the water, which is quite different from other amphibians. This may be related to the characteristics of its larvae, such as the exposed skin of its larvae, and remain swayed until adulthood.
