The Deepest Fish

How deepest the fish could live in the sea?? Do you know? From my reading of marine sciences article, the world's record holder for deepest fish goes to the ‘brotulid’ family, about which scientists know almost nothing. These fish are benthopelagic, living at depths of 7000 meters or more. The world's deepest fish (Abyssobrotula galatheae) was found in the Puerto Rican Trench at a depth of 8,372 meters (that's over five miles down!). Their eyes appear to be virtually nonexistent. Maybe it's because there is never enough light for the fish to see, so why bother with the eyes? After all, eyes in most organisms are designed for gathering light in the creature's visual field and transmitting it to the brain, giving it useful information about its environment. In a world where no sunlight ever penetrates there's probably little use for eyes. So, maybe YOU could be the scientist who studies this species and unravels its mysteries.

M16

What you think in your mind when see the word M16?? Maybe you know about M16, or maybe not. Actually the M16 is a lightweight, 5.56 mm caliber, air-cooled, gas-operated, magazine-fed assault rifle, with a rotating bolt, actuated by direct impingement gas operation. The rifle is made of steel, aluminum, and composite plastic. Malaysian army and police also use this type of weapon. It was semi-automatic rifle that can achieve more than 200m shooting distances. I had an experience in using this weapon. I had used this weapon during my training for police cadet and for shooting tournament by using M16 for 100m shooting distances. It was unforgettable experiences in my life although I feel like to be a deaf and made my sense of hearing trouble for a couple days. If you were there during my training, your head will be exploding because of shooting sound.
