Squid: A Delicious and Nutritious Seafood

If you are looking for a tasty and healthy seafood option, you might want to consider squid. Squid is a versatile ingredient that can be cooked in various ways and paired with different sauces and spices. It is also a good source of protein, omega-3 fatty acids, zinc, manganese, and other nutrients. In this article, we will explore what squid is, how to cook it, and what are its health benefits.


What is Squid?

Squid is a type of cephalopod, a class of mollusks that also includes octopus and cuttlefish. Squid have a soft body with a mantle that contains their organs, a head with two large eyes and a beak-like mouth, eight arms with suckers along their length, and two longer tentacles with enlarged tips that they use to catch prey. Squid also have an internal shell called a pen that supports their body structure.

Squid vs Calamari

Many people use the terms squid and calamari interchangeably, but they are not exactly the same thing. Squid is the name of the animal itself, while calamari is the name of a dish made from squid. Calamari usually refers to squid that has been cut into rings or strips and deep-fried in batter. However, calamari can also be cooked in other ways, such as grilled or stewed.

Types of Squid

There are more than 300 species of squid in the world, ranging in size from less than an inch to over 40 feet long. Some of the most common types of squid that are eaten as food are:


European squidA medium-sized squid that has purple spots on its body and can grow up to 16 inches long. It is widely fished in the Atlantic Ocean and the Mediterranean Sea.. Japanese flying squidA small squid that can grow up to 12 inches long. It is named for its ability to jump out of the water and glide for short distances. It is mainly caught in the Pacific Ocean near Japan.

Humboldt squidA large squid that can grow up to 6 feet long and weigh up to 100 pounds. It is also known as the jumbo squid or the red devil. It is found in the eastern Pacific Ocean from California to Chile.

Giant squidA colossal squid that can grow up to 43 feet long and weigh up to a ton. It is one of the largest living animals in the world and a deep-sea dweller. It is rarely seen by humans and has been the subject of many myths and legends.

  • Cut off the tentacles just below the eyes and set them aside.

  • Feel inside the body for a long, plastic-like quill and pull it out.

  • Peel off the purple and white skin from the body and discard it.

Cooking Methods

Squid can be cooked using different methods, such as frying, grilling, or stewing. The key is to cook it quickly over high heat, or slowly over low heat, to avoid overcooking it. Here are some examples of how to cook squid:
