6. Mouthparts
Fleas have piercing mouthparts that they use to feed on blood. These mouthparts are located on the underside of the head and are made up of two sharp, pointed mandibles and two maxillae. The mandibles are used to pierce the skin of the host, while the maxillae are used to suck up the blood.
-
Facet 1: Appearance
The piercing mouthparts of fleas are not visible to the naked eye. However, they can be seen under a microscope. The mouthparts are relatively long and thin, and they are usually held close to the body of the flea.
-
Facet 2: Function
The piercing mouthparts of fleas are used to feed on blood. Fleas are obligate blood feeders, meaning that they must consume blood in order to survive. They typically feed on the blood of mammals, but they can also feed on the blood of birds and reptiles.
-
Facet 3: Disease transmission
The piercing mouthparts of fleas can also be used to transmit diseases. Fleas can transmit a number of diseases to humans and animals, including typhus, the plague, and tularemia. These diseases can be serious, and in some cases, they can be fatal.
