Fake squid may be made of different materials, including flour, starch, seaweed, fish and so on. The specific ingredients depend on the manufacturer's formula and purpose.

As for whether squid can be made artificially, it is actually possible. This involves a technology called "artificial meat" or "vegetable meat", which uses various vegetable proteins or other ingredients to simulate the taste and nutrition of meat or seafood. However, these products are not usually called "squid", but are called by names like "vegetarian squid" or "artificial squid". These products may be different from real squid in appearance, taste and nutrition.
