Bites are usually classified by the type of<unk>  causing the wound. Many different<unk> s are known to bite humans. Vertebrates Jaw of the piranha with biting equipment displayed *Companion<unk> s, including dogs, cats, rats, ferrets, and parrots, may bite humans. *Wildlife may sometimes bite humans. The bites of various mammals such as bats, skunks, wolves, raccoons, etc. may transmit rabies, which is almost always fatal if left untreated. *Human bites are themselves capable of doing great flesh damage, but are particularly known for spreading communicable diseases Involuntary biting injuries due to closed-fist injuries from fists striking teeth (referred to as reverse bite injuries) are a common consequence of fist fights. These have been termed "fight bites". Injuries in which the knuckle joints or tendons of the hand are bitten into tend to be the most serious. Teething infants are known to bite objects to relieve pressure on their growing teeth, and may inadvertently bite people's hands or arms while doing so. Young children may also bite people out of anger or misbehaviour, although this is usually corrected early in the child's life. Reverse bite injury A reverse bite injury (also called a clenched fist injury, closed fist injury, or fight bite) results when a person punches another person in the face, and the skin (and sometimes tendons) of their knuckles are cut against the teeth of the person they are punching. The proximity of the wound is often located over the metacarpophalangeal joint resulting in tendon injury. The medical treatment of this injury is similar to those of a human bite, but may also involve damage of the underlying tendons. These injuries should be managed as other human bites: wound irrigation and antibiotics are essential as human saliva can contain a number of bacteria. The nature of these injuries is such that even if the injury is optimally managed, poor outcomes may still occur. Arthropods The bites of arthropods have some of the most serious health consequences known. Mosquito bites transmit serious disease and result in millions of deaths and illnesses in the world. Ticks also transmit many diseases such as Lyme disease.
