ectoparasites
They are called parasites... they live off of their host
Parasites are animals that live inside other animals.
No, pubic lice are ectoparasites; they live on the outside of the body.
Worms are normally not external parasites, but internal parasites. External parasites include different arthropod species like ticks, fleas, lice, mosquitos....
They either live on (eat) the animal they are in, or live on the food that the animal eats.
A parasite has one main function - to derive its most basic needs (food, shelter, safety) off of a host. The host may or may not permit the parasite to stay, depending on the circumstances. They only take, they do not give anything to the host except for potential pain and/or suffering in some form.
The two types of parasites are:- 1) Ectoparasites :- Parasites which live on the external surface of the host are called ectoparasites. Examples :- 1. Animals - Ticks, Mosquitoes, Bed-bugs, Head louse, Leeches etc. 2. Plants - Cuscuta, Loranthus 2) Endoparasites :- Parasites living within the host are called endoparasites. Examples :- 1. Animals - Liverfluke, Tapeworm, Ascaris, Plasmodium 2. Plants - Many fungi.
Parasites live on a host in both plant and animal world. E.g. Staghorns live on the trunk of a host tree. Animal world a tick will live on a host animal i.e. a dog. Hope that helps.
Internal parasites in cattle can be worms in the intestinal tract and external ones would be ticks, flies and fleas on their skin.
Their skin harbors many external parasites, such as crabs, which are eaten by oxpckers and egrets that live with the rhino.
Ectoparasites are external parasites. Lice or fleas are examples.
