Do the ink that comes from a squid or octopus hurt?

The ink released by squids and octopuses is primarily a defense mechanism and is not harmful to humans. While it may cause temporary irritation if it comes into contact with skin or eyes, it is generally not toxic. The ink can also make it difficult for predators to see, allowing the cephalopod to escape. Overall, while it may cause some discomfort, it is not considered dangerous.
