Gibbon dancing for eclipse

The eclipse of the solar eclipse on May 21 caused many strange tailed lemurs in Japan to behave strangely.

About 20 bell-tailed lemurs in the Japanese Monkey Center in Aichi Prefecture jumped or stumbled up trees, columns when the moon obscured the sun on May 21, AFP reported. Akira Kato, the director of the center, said it was the unusual behavior of bell-tailed lemurs in the daytime.

"They usually perform those actions in the evening to increase their body temperature," Kato said.

After the eclipse ended, the monkeys returned to their normal state. They continue to carry out the typical actions of the day - like lying on the sun, chewing on the grass.

Kato explained that the eclipse caused the gibbons to mistakenly think the sun had set. So they carry out the typical actions of the night.

The eclipse of the moon occurs when the moon enters between the sun and the earth. They lie in a straight line, but because of the apparent size (the size that the human eye perceives) of the moon is smaller than the apparent size of the sun, the moon does not completely obscure the sun. So the observer on Earth will see a bright belt of light surrounding the moon as it reaches the middle of the sun.

Although solar eclipse is an interesting phenomenon, it can cause consequences for the eyes if people observe incorrectly. According to statistics from the Japan Society of Ophthalmology, at least 16 people had to go to the doctor due to eclipse keratitis syndrome. The manifestation of the syndrome is that people feel burning pain, eye irritation, reduced vision. People who use eclipses do not meet the standards and look at the sun for too long and suffer from keratitis. Most patients will return to normal after a few days.
