It’s time that I introduce you to the guests of honor of my posts, the jumping spiders, known to biologists by the name “Salticidae”.
Imagine a miniature cat, 5 millimeters long, spotting prey with keen eyesight, walking carefully toward the prey, then crouching down, inching forward stealthily, tensing its legs, then pouncing with deadly accuracy.
That pretty much describes a jumping spider. They hunt like cats, using their acute vision and jumping ability.
Like most spiders, jumping spiders have 8 eyes. Six of these look all around, like our peripheral vision.
The two other eyes, in the front middle, are like our fovea, our central vision: narrow field of view, but high resolution.
These are the great big eyes in the middle of their faces. You can see photos of these special eyes and how they move in my account of a transparent jumping spider from a recent expedition to Ecuador.
What’s remarkable is that they can achieve such an acute visual system in such a small package.
