How do sea snails protect themselves from predators?

Sea snails are a type of marine gastropod mollusk that have evolved various mechanisms to protect themselves from predators. Some of these defense mechanisms include:

• Camouflage: Many sea snails have the ability to blend in with their surroundings to avoid detection by predators. Some species have shells that match the color and texture of their environment, while others have the ability to change color to match their surroundings.
• Shell thickness: Some sea snails have thick, hard shells that are difficult for predators to break or penetrate. Others have spiny or ribbed shells that deter predators from attacking.
• Toxins: Some sea snails have developed the ability to produce toxins that make them unpalatable or even poisonous to predators. The toxins can be found in the snail's flesh or in its mucus, which it secretes as a defense mechanism.
• Escape behavior: Some sea snails are able to detach from their shells and swim away from predators. Others have a trapdoor-like structure called an operculum that they can use to seal themselves inside their shell.
