Squid

The Squid is an aquatic invertebrate animal with eight arms and two tentacles arranged in pairs. Squids have several species, but they have some common characteristics. For instance, all squids have tentacles with suckers, a mouth with a radula, and jet propulsion with the siphon from the mantle. The radulla is a scraping organ in the mouth that scrapes nutrients from food sources. Tentacles are long extensions of specialized tissues from the body that are used for locomotive power and capturing food sources. All squids are carnivores. The main body mass of the squid is enclosed in the mantle, which has a swimming fin along each side. It should be noted that these fins, unlike many other marine organisms, are not the main source of ambulation in most species.

Although native to Earth, squid have been introduced to UNSC colonies such as Emerald Cove. SPARTAN-II Grace-093 enjoyed eating squid while there on a training mission with John-117, Frederic-104, and Anton-044.
