Accordingly, what colors do spiders see?

Most humans have trichromatic vision -- they have retinal cells called cones that can see red, green and blue. Wolf spiders, by comparison, have dichromatic vision and see only green and ultraviolet. "That means they're basically colorblind. But they're sensitive to light in the green wavelength," Uetz said. One may also ask can you drown a spider? "Flushed spiders will drown if they end up submerged in the sewer," Jerome Rovner, a member of the American Arachnological Society, told Real Clear Science. "However, the drowning process for a spider can take an hour or more, as they have an extremely low metabolic rate and thus a very low rate of oxygen consumption."

Can a spider escape from under a glass?

Spiders have a very slow metabolism, compared to most mammals, and need only a tiny amount of oxygen to survive.
