What kind of darts that put animals to sleep?

Darts that put animals to sleep typically contain anesthetics or tranquilizers, such as ketamine or medetomidine, and are used in wildlife management and veterinary medicine. These darts are delivered via a dart gun or blowpipe and are designed to safely sedate animals for procedures like capture, relocation, or medical treatment. The dosage and type of drug are carefully calculated based on the animal's size and species to ensure effectiveness and safety.
