This Jumping Spider Trains Itself to Kill | KQED
Briefly

The regal jumping spider, despite her small size, becomes a formidable predator through self-teaching. Female jumping spiders require a mate for reproduction, leading to an elaborate courtship display. After mating, she lays 50-200 eggs, protected by a silk sac, serving both as a nursery and play area for her spiderlings. These young, equipped with eight eyes, learn to hunt instinctively, navigating their environment through trial and error, enhanced by acute vision adapted for daylight. Her maternal care is crucial in their early development.
The size of a bottle cap, she had to teach herself how to be this fearsome, starting when she was smaller than a sesame seed. Every jumping spider must learn to stalk and pounce - they don't use a web to catch prey.
When they hatch, the nest serves as both their nursery and a silky jungle gym. They grow up here under the many watchful eyes of their mom.
Jumping spiders' keen eyesight is fine-tuned for daylight hunting. They have eight eyes. The three smaller pairs on the sides see motion, making it hard for predators to sneak up on them.
Their central pair are their principal eyes that allow them to see crisp detail and vivid color. They also help these cuties judge distance so they can land on target.
