Is squid same as shrimp clams etc?

No, squid, shrimp, and clams are not the same. They are all different types of seafood, but they belong to different taxonomic groups and have distinct characteristics.

Here's a breakdown:

* Squid are cephalopods, which are a class of marine mollusks. They have a distinct head with tentacles, a beak-like mouth, and an internal shell. They are known for their intelligence and ability to change color.

* Shrimp are crustaceans, a class of arthropods with an exoskeleton. They have a segmented body with a head, thorax, and abdomen. They are often found in coastal waters and are prized for their delicate flavor.

* Clams are bivalve mollusks, a class of mollusks with two hinged shells. They are filter feeders that live in saltwater or freshwater environments. They are a popular seafood choice for their meaty texture.

While they all belong to the broader category of seafood, they have distinct biological and culinary characteristics.
