Squid and Octopus

Squid are mollusks like clams and oysters but they have no shells on the outside of their bodies! They have a shell inside their bodies called a pen.

Squid Facts
Five groups that classify all living things...

Giant squids: A live giant squid was observed for the first time on September 30, 2005, by two Japanese scientists: Tsunemi Kubodera of the National Science Museum (of Japan) and Kyoichi Mori of the Ogasawara Whale Watching Association.

Squids are fast-swimming, predatory molluscs. They locate their prey by sight, and ensnare the victim by shooting out two of their tentacles armed with suckers or hooks. The prey is then killed by a bite from the squid's beak.

They eat everything from ~ to shrimp, baitfish and even eels, which makes them easy to target with spinning, plug or fly tackle. My favorite way to target cobia is with fly tackle and large poppers, although chartreuse colored jigs or Bass Assassin 5-inch swimbaits are also deadly on these fish.
