The Gills
A squid's mantle is used for various functions, including respiration, feeding, reproduction, and propulsion. It also houses the squid's internal organs and provides protection from predators. Additionally, the mantle is the site where ink production takes place for defense mechanisms against predators.
Well, the mantle is esentiallly the head, and body, of the squid. It has all the organs and on the bottom is the beak.
Lungs and Gills are both used for external respiration
Animals = lungs Fish = gills

The parts of a squid that are typically not eaten include the beak, which is hard and resembles a bird's beak, and the ink sac, which contains ink used for defense. While the ink can be used in cooking, it is generally not consumed directly. Additionally, the internal organs, such as the digestive gland, are usually removed before cooking.
The squid's ink amount depends on the size of the squid. The ink is used to confuse and paralyze the squid's attacker so that the squid can escape.
In restaurants, this is what Calamari is.
Squid use a kind of jet power. Water is squirted at great pressure out of a nozzle on the squid's body. At times the squid can swim so fast that it may pop out of the water and glide through the air at 25 to 40 miles per hour. A squid may fly for 100 feet or more before it splashes back into the water.
The main organs used for respiration include the lungs, where oxygen is taken in and carbon dioxide is expelled, and the diaphragm, a muscle that aids in the breathing process by helping to expand and contract the lungs. Additionally, the trachea (windpipe) and bronchial tubes help to conduct air into and out of the lungs.
The word squid is usually used as singular or plural, examples: Singular: A squid was caught on my line. Plural: The restaurant had a tank of live squid on display. That being said, some people do squids as the plural form.
