Name and describe a category of vegetarianism.

Pescetarianism is arguably a form of vegetarianism:

Pesecartianism is where one will eat eggs, dairy foods, vegetables, fruits, seeds, etc. and fish. Pescetarianism is considered not vegetarianism by some vegetarians but it is argued by others that it is a form of vegetarianism.

If this doesn't work, then try veganism, veganism is eating absolutely no animal by-products, therefore no meat, eggs, dairy, or anything.

I hope this helps.
