Squid respire via the mantle; water is pulled in, pushed across the gills, and then expelled via the exhalent siphon of the mantle.
The structure of a squid's gills allows for efficient exchange of oxygen and carbon dioxide between the water and the squid's bloodstream. This enables the squid to extract oxygen from the water for respiration and release carbon dioxide as waste. The gills are highly vascularized and have a large surface area to maximize this gas exchange process.
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.
Squid, like other cephalopods, lay eggs. When an egg hatches, the immature squid is referred to as a larva (plural larvae).

The pen is a feather-shaped internal structure that supports the squid's mantle and serves as a site for muscle attachment. It is made of a chitin-like substance. It is the remnant of the squid's shell, so it is a vestigial structure.

The Gills
Gas exchange is accomplished by pair of bipectinate, nonciliated gills.
Squid obtain oxygen from the water by passing it over their gills. As water flows through the gills, oxygen is absorbed into their bloodstream and carbon dioxide is released back into the water. This allows the squid to extract oxygen from their watery environment for respiration.
Squid use oxygen from seawater for respiration. The seawater enters the mantle through the opening near the head, and passes over the gills. Oxygen diffuses from the water into the blood, and is transported to the gill (or branchial) hearts by a network of many blood vessels.

The Humboldt squid and the Giant Squid are two separate species
The squid is called a firefly squid.
but what the squid
Squid by far. Squid by far.
The Giant Squid is a cousin of the Squid.
