A dart syringe projectile includes a tubular body front and rear ends and a bore extending between said ends. A needle assembly is mounted on the body front end and a tail assembly is mounted on the body rear end. The body bore or the tail assembly receives a striker, a percussion cap positioned in front of the striker, an explosive charge positioned in front of the percussion cap and a plunger positioned in front of the explosive charge. A reservoir cavity in front of the plunger receives a substance for injection. The dart syringe projectile has a flight configuration with the substance in the reservoir cavity and an injection configuration with the plunger propelled forwardly by the explosive charge and the substance discharged from discharge ports in the needle, which are in spaced relation behind a needle tip.

An animal injection system under the control of a remote operator. The system may be used to inject animals with medications and/or RFID chips. Food bait is provided in such a manner as to require an animal to expose its chest and underside. Cameras are used to determine the orientation of the animal and its gender. Images of the animal are sent to the remote operator who determines whether or not to inject an animal. Cellphone networks may be used to transmit animal images to the remote operator and send commands from the operator to the injection system. The system may include a temperature control system to maintain medications in a pre-selected temperature range.
