The Marine world The fish world is like a horror movie they can't sleep at night or play during the day The small fish is hunted by bigger fish that again is chased by sharks and dolphins. The whale that is not a fish lives in relative safety because of its size, but is hunted by with harpoons that tear into flesh colouring the sea, red. Many people are defending the whale, not so many are concerned by the humble sardine, if you swim in a school of sardines, they will do you nothing, the same cannot be said if you meet octopuses with their arms break your bones and swallow your whole. I prefer to bath in a swimming pool where the bottom is painted blue and it no deep than, say, four feet.
