The name Pescatarian is derived from the Latin word for fish ‘piscis’. Unlike vegans and vegetarians, the consumption of fish and seafood is a fixed part of the diet of pescatarians. They only abstain from the meat of warm-blooded animals, such as cattle, pigs, sheep and poultry, etc. Pescatarians can essentially be classed as vegetarians, as they have animal-based foods such as eggs, milk and honey, from live animals in their diet.
