If I only eat crab meat am I a pescatarian or something else?

If you eat seafood you are a pescatarian.

If you eat no meat at all you are a vegetarian.

If you are a fish and you are eating another fish you would not be a pescatarian. A pescatarian is a vegetarian fish and I doubt you are even any type of fish as you seem to type and speak english something I doubt most if not all fish can do. However if you eat crab or any other animal flesh you are what is referred too as an omnivore or in some cases a picky eater. There are no special terms for people who only eat one kind of animal flesh because they are still murdering animals for their diet and do not need and should not use any special terms for their diet.

If you like crab rangoon go up to NYC check out Red Bamboo http://www.redbamboobrooklyn.com/ they have a vegan rangoon which is not much different than the regular stuff except it is better and cruelty free.

A crab is an animal.

One who eats animals and plant matter is an OMNIVORE.
