Squids are fascinating sea creatures that belong to the class Cephalopoda, which also includes octopuses and cuttlefish. They have long, soft bodies and are known for their ability to swim quickly by expelling water from their bodies. Squids come in various sizes, with some being just a few inches long, while others, like the giant squid, can grow to over 40 feet! One of the most interesting features of squids is their ability to change color and texture using special cells called chromatophores. This helps them communicate with each other and blend into their surroundings to avoid predators. Squids are also known for their intelligence and complex behaviors, making them unique among marine animals.
