context_page_description: Some people do not eat various specific foods and beverages in conformity with various religious, cultural, legal or other societal prohibitions. Many of these prohibitions constitute taboos. Many food taboos and other prohibitions forbid the meat of a particular animal, including mammals, rodents, reptiles, amphibians, fish, molluscs, crustaceans and insects, which may relate to a disgust response being more often associated with meats than plant-based foods. Some prohibitions are specific to a particular part or excretion of an animal, while others forgo the consumption of plants or fungi.
  Some food prohibitions can be defined as rules, codified by religion or otherwise, about which foods, or combinations of foods, may not be eaten and how animals are to be slaughtered or prepared. The origins of these prohibitions are varied. In some cases, they are thought to be a result of health considerations or other practical reasons; in others, they relate to human symbolic systems.
  Some foods may be prohibited during certain religious periods, at certain stages of life, or to certain classes of people, even though the food is otherwise permitted.
context_section_description: Almost all types of non-piscine seafood, such as shellfish, lobster, shrimp or crayfish, are forbidden by Judaism because such animals live in water but do not have both fins and scales.
  As a general rule, all seafood is permissible in the 3  madh'hab of Sunni Islam except Hanafi school of thought. The Ja'fari school of Islamic jurisprudence, which is followed by most Shia Muslims, prohibits non-piscine (lacking scales) seafood (with the exception of shrimp).
