The common basilisk or Jesus Christ lizard is a reptile that lives in wet forest waters in Costa Rica, Central America, between the Pacific Ocean and the Caribbean Sea.
It is a member of the lizard family with a bright green body and can grow up to 80 centimeters in length.
Adult males have a large crest on their heads, while females have no crest.
Has yellow eyes.
It has fins on its back, with green, white, and black scales mixed together.
This is to threaten the enemy.
This lizard usually moves little and is slow, but it is very fast when hunting.
It is an omnivore that eats everything from fruits such as mangoes and bananas to mice and birds.
Basilisk lizards can run on water, dive, and swim very well.
뱀처럼 꿈틀거리며 물속을 헤엄쳐 다닙니다.
Sleeping in the water or diving for long periods of time.
The principle of diving for a long time is to conserve energy as much as possible.
이 도마뱀은 새와 같은 천적의 위험을 피하기 위해 잠수합니다.
• Origin of name
The reason why this lizard was given the monstrous name 'Basilisk' is because Europeans were very afraid of it because it was said that if it looked at its eyes, it would die or turn to stone.
In other words, the monster and the lizard looked very similar.
Another name is Jesus Lizard, named after the image of Jesus walking on water.
• 물 위를 달리는 바실리스크 도마뱀.
이 도마뱀은 일반 카메라로 촬영하고 천천히 재생해도 거의 볼 수 없을 정도로 물 위를 빠르게 달리는 도마뱀입니다.
It runs so fast that it can only be analyzed if taken with a highspeed camera (the shutter speed of a highspeed camera is one millionth of a second).
When a basilisk lizard runs on water, it takes five steps in 0.25 seconds.
One second is equivalent to walking twenty steps.
The time your feet are in the water is very short.
한 걸음인 약 0.05초 간격으로 한 발이 물 밖으로 나오고 반대쪽 발이 빠르게 움직인다.
물을 이겨내고 앞으로 나아갈 수 있습니다.
Therefore, the only things in the water are the feet and the tail.
• 물 위를 달릴 때 생성되는 힘.
도마뱀이 달릴 때 물과 상호작용하는 세 가지 힘이 있습니다.
First, friction.
물 위를 밟는 원리는 땅을 밟는 것과 마찬가지로 발이 물 표면에 닿아 있는 것입니다.
When your feet enter the water quickly, resistance is created.
The second is the actionreaction law (Newton's law of motion).
The reaction of the feet pressing against the water and the water pushing the feet at the same time makes the lizard float.
세 번째 힘은 부력이다.
발이 공중에 떠서 물에 들어가면 공기와 함께 물 속으로 들어갑니다.
At this time, the air surrounding the foot acts as a bladder.
Therefore, the body does not sink due to these forces.
These forces all occur when you place a strong foot on the water and move your other foot before sinking.
When viewed from the front when running on water, it appears as if the legs are spread wide and stretched out to the sides.
To run fast, you move your legs as if you were rotating your arms quickly and widely.
However, you cannot run on water with just your legs.
뒷발에도 도움이 됩니다.
There are scaly wrinkles on the entire hind toes.
It is normally folded and only unfolds when it touches water.
Because of these wrinkles, the area where the water and feet come in contact with each other expands, and the water resistance increases accordingly.
