The Long Fin Inshore Squid is a reddish color depending on environment. Their dorsal mantle is 30-50 cm long. The males are bigger than the females. The juvenile squid eat plankton organisms, crustaceans, small fish, arrow worms, and shrimp. Adult squid eat fish, crustaceans, and other squid. During their gas exchange they draw water through a siphon into the mantle, where it passes over the gill filaments, which absorb oxygen and release carbon dioxide. They have a two branchial heart at the base of the gills which send un-oxygenated blood through the gills. Then the third ventricular heart pumps this oxygenated blood throughout the body. Small crustaceans can become tiny parasites when they inhabit a squid's gill, mantel, or skin. Cephalopods don't have a specific immune response and don't have immunological memory. Squid are cold-blooded. They don’t need body fat or high metabolism to keep them warm. They maintain homeostasis by relying on their surroundings to keep themselves warm. Some species of squid live in warmer habitats, and other live in colder habitats. Squid slow down to conserve heat. They also swim closer to the surface to conserve the heat. Maturity is reached at 3-5 years. Most squid are only able to mate once. When mating squid swim in circles, and the males change color, then they pair up. In female, ink sac under glands in gills protects eggs. Sperm is deposited into the sac. Female can produce thousands of eggs at a time. The eggs are hidden under rocks or holes. Females leave and it is up to 8 weeks before eggs hatch. Squids move by using their release of Carbon dioxide to push them forward. The long fin inshore squid is found in the North Atlantic, Continental shelf, slope waters, and Newfoundland(the cape of Venezuela).
