What is the difference between squid and lobster?

Squid and lobster are both marine animals but belong to different classes; squid are cephalopods, while lobsters are crustaceans. Squid have elongated bodies, tentacles, and are known for their ability to change color and squirt ink, while lobsters have a hard exoskeleton, large claws, and a more robust, compact body. Additionally, squid are typically found in open waters, whereas lobsters are often found on the ocean floor in rocky or sandy environments. They also differ in culinary uses and textures, with squid being more tender and often served fried or grilled, while lobsters are prized for their rich, sweet meat.
