In reality, these spiders are harmless. They rarely attack humans and they prefer scurrying away. They have venom but these are only enough to immobilize their prey (small insects).
Unlike other spiders, huntsman spiders don't build webs to catch prey. Instead, they forage and hunt.
Intimidating as they may look, huntsman spiders are not enemies. They're friends. They can help get rid of pests like cockroaches in your home.
