1 When Denzel Washington talks about challenging death to a wrestling match, you suddenly sense that everythingâs going to be all right.
Now we know that fish with scales AND fins are equipped with a digestive system that prevents the absorption of poisons and toxins into their flesh from the waters they call home. Flounder, cod, haddock, and salmon are a few examples of fish with scales and fins. Catfish have fins, but do not have scales. These scavengers are primarily bottom feeders and have digestive systems designed to absorb toxins from the water. Clams, lobster, shrimp, crabs, mussels and squid do not have scales or fins and are believed to be highly toxic. They naturally absorb all the toxins in the water they live in.
The paired tail fin is attached to the upper surface of the mantle and is made up of muscle. The colossal squid swims forward through the water by undulating the fin longitudinally. The fin is unusually massive and muscular (1,183 millimetres long and 982 millimetres wide). This probably enables the colossal squid to move forward quite rapidly in short bursts when attacking prey.
