it is when water molecules in the water form a 'wall'.Pond skaters have legs that spread out away from their bodies, lowering the pressure exerted by their weight and not breaking the surface tension of the water
Surface tension on water allows insects to walk on water including Spiders. With fuzz, or hair on their legs, their light weight bodies can easily walk on water without breaking the surface tension.
Surface tension allows it to walk on the surface of water.
To this phenomenon contribute: water surface tension, nonwettable legs of the insect, weight of the insect distributed on large area.
Surface Tension
the answer is surface tension
Cohesion
There are no actual species of spider called wood spiders, but people call brown spiders that live in wood piles, "wood spiders."
8 eight is the amount a cnidarian have also spiders
All species of spiders are arthropods, and arthropods have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
Spiders come in various shapes and sizes. The tallest spider is the Darwin's back. It can create webs that stretch 80 feet across rivers.
The Black Widow and Brown Recluse are the only dangerous spiders in Virginia.Spiders are annoying especially when you sleep in a basement! I can not say that I have seen a Black Widow in Virginia though.Golden garden spiders have a rather flat head and a thorax region covered with whitish hair. They are black with yellow markings.Large orb weavers are found about houses in the fall. Their legs are usually shorter and their bodies not as big as the golden garden spider.Wolf spiders are usually large, hairy spiders that are not associated with webs. They look much worse than they are.Jumping spiders do just that-jump! They are small, usually black with red or white markings, and are often found in windows. They rarely bite.House spiders have "dirty" white and gray markings on their abdomen. They build complicated webs in corners, under tables, chairs, etc.Sheet web spiders have a pair of dark bands across their yellowish head-thorax and abdomen region. They are common on shrubs and weeds around the house.

In physics, surface tension is a force present within the surface layer of a liquid that causes the layer to behave as an elastic sheet. It is the force that supports insects that walk on water, for example.
Push a box across a surface with a downward angle because gravity is helping.
They walk on the water lightly so that they do not break the surface tension of the water.
it's called "surface tension". It is the property of the surface of a liquid which causes it to behave like an elastic sheet. This is why a "water strider" insect can skate across the surface of a pond without sinking into the water. It is also what causes a drop of water - the surface tension of the water pulls it into a ball.
"surface tension"
A dam is a structure built across the water to hold water back.
In the barnyard,in the chicken coop, on the fence across the road and in the haystack looking for spiders.
I've seen spiders with a row of eyes across their foreheads.
No the world's biggest spider is still only a foot across
Decrease in alveolar surface area results in less boundary across which oxygen can be absorbed into the blood.
