The practice of eating live seafood, such as fish, crab, oysters, baby shrimp, or baby octopus, is widespread. Oysters are typically eaten live. The view that oysters are acceptable to eat, even by strict ethical criteria, has notably been propounded in the seminal 1975 text Animal Liberation, by philosopher Peter Singer. However, subsequent editions have reversed this position (advocating against eating oysters). Singer has stated that he has "gone back and forth on this over the years", and as of 2010 states that "while you could give them the benefit of the doubt, you could also say that unless some new evidence of a capacity for pain emerges, the doubt is so slight that there is no good reason for avoiding eating sustainably produced oysters".
|China||Drunken shrimp||Drunken shrimp is a popular dish in parts of China. It is based on fresh-water shrimp that are placed in a strong liquor, baijiu, and then eaten, often while they are alive. Modified recipes are used in different parts of China. For example, the drunken shrimp can be cooked in boiling water instead of serving them while they are still live. In other recipes, the shrimp are boiled first and then marinated in alcohol.||YouTubeon|
|Yin Yang fish||Yin Yang fish, or dead-and-alive fish, originated in Taiwan. It is a dish which consists of a deep-fried whole fish (usually carp) that remains alive after cooking. The fish's body is cooked while its head is wrapped in a wet cloth to keep it breathing. The fish is then covered in sauce and served live on a plate. Some chefs say they prepare the fish this way to demonstrate its freshness to the customer. Preparation of this dish is now prohibited in Taiwan and illegal in Australia and Germany.||Eating A Deep Fried Fish That's Still Alive – Huffington Post|

Octopuses are eaten alive in several countries around the world, including the USA. Animal welfare groups have objected to this practice on the basis that octopuses can experience pain. In support of this, since September 2010, octopuses being used for scientific purposes in the EU are protected by EU Directive 2010/63/EU "as there is scientific evidence of their ability to experience pain, suffering, distress and lasting harm." In the UK, this means that octopuses used for scientific purposes must be killed humanely, according to prescribed methods (known as "Schedule 1 methods of euthanasia").
London resident Louis Cole runs a YouTube channel in which he eats live seafood. The Guardian commented on the ethical issues raised by the behaviour of Coles that: "It seems objectively less cruel to kill a scorpion instantly than to rear chickens in battery cages or pigs in the most miserable pork farms.
