How does a colossal squid breathe?

How does a colossal squid breathe?

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.

Can giant squid come to the surface?

In 2004 researchers in Japan took the first images ever of a live giant squid. And in late 2006, scientists with Japan’s National Science Museum caught and brought to the surface a live 24-foot female giant squid.
