The video shows a large black spider with long legs and hairy body. The spider is seen crawling on a bed of wood shavings. In the background, there is a small caterpillar crawling on the same surface. The spider approaches the caterpillar and appears to bite it. The caterpillar wriggles as the spider holds it with its legs. The spider then starts to eat the caterpillar. The video is shot in close-up, allowing for a detailed view of the spider's movements and the caterpillar's struggle.
