TITANOBOA: MONSTER SNAKE: Smithsonian Channel unveiled a scientifically accurate life-size replica of Titanoboa, the biggest snake to have ever roamed the earth, in Grand Central Terminal Thursday morning to astonished commuters. The 48 foot long behemoth lived 60 million years ago during time just after dinosaurs became extinct.
The Leatherback Sea Turtle is the largest turtle in the world, weighing approximately 900kg. Contrary to appearance, the leatherback doesn't actually have a shell. What looks like a shell is in fact a leathery skin supported by small bones. This gives it a flexibility that a solid shell would not provide, allowing it to dive to astonishing depths.
