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.
Those of the giant squids reach a length of 10 meters for the tentacles, and 3 meters for the arms. The tentacles are what are used to catch prey. The lower surface of these arms is covered with two rows of suckers. The tentacles of squid and octopi do have a difference.Squids have extra armature-hooks on the sucker rings.he pattern in which squid move, pumping water through the mantle, is also how squid breathe. Most sea animals have visible gills, but squids do not possess gills like most fish do, instead they obtain oxygen through a pair of long âgillsâ covered in leaflets called lamellae.
