Answer:
Ectoparasites:
1. Ectoparasites live on the surface of the host.
2. They can be temporary, intermittent or permanent.
3. They can be hemiparasites or holoparasites.
4. Respiration is aerobic.
5. Specialisation has led to loss of fewer structures, e.g., wings in fleas, bedbugs and lice.
Endoparasites:
1. Endoparasites live in the body of the host.
2. They are generally permanent parasites.
3. They are usually holoparasites.
4. Respiration is often anaerobic.
5. Specialisation has led to the loss of several structures, e.g., digestive organs in Taenia.

Endoparasite and ectoparasite etymology:
The etymology of the word ?parasite? goes back to the 1530?s. In Greek, "para" translates to "alongside" and "sitos" translates to "food." Combined, "parasitos" means "a person who eats off another's table". This word, though not used for biological parasites until much later, was used in the 16th century to refer to people who often ate others' food, often the rich, and they flattered the rich to earn this food.
The scientific use of the word "parasite" is first recorded in the 1640's. The scientific meaning is an organism that lives at the expense of and gains resources from another organism. This increases the parasite's fitness while decreasing the host's fitness.
Adding the prefixes "endo" or "ecto" add specificity to how a parasite lives. Both prefixes are Greek as well. "Endo" means inside, so a parasite living within the host, and "ecto" means outside, so a parasite living on the host.
