Dart gun

Non-lethal gun used to paralyze animals

A dart gun is an air rifle that fires a dart. The dart is tipped with a hypodermic needle and filled with a sedative, vaccine or antibiotic. A dart gun containing a sedative is called a tranquillizer gun, derived from the word "tranquil", which means "calm".
