THERE ARE 600 SPECIES OF CARNIVOROUS PLANTS
Most carnivorous plants had
to adapt because their environments that no longer produced the nutrients they
needed to flourish. Just like most species, they'll do what they can to
survive. For many meat-eating plants, that means gulping down bugs, but for some
it even extends to feeding on mice and frogs. They present many clever ways to
lure in their prey to swallow them up.
Snap Traps: The most well-known plant to use the snap trap is the Venus flytrap. When opens, it offers what looks like a bright red landing pad for flying creatures. The plant has trigger hairs that, once touched, alert it to snap shut, often capturing its prey inside. As its victim struggles to escape, the plant is triggered yet again and continues closing until it becomes airtight. The bug eventually suffocates and the Venus flytrap absorbs its fluid. That's a pretty sophisticated mechanism.
Glue Traps: Glue seems perhaps the most obvious way to trap a fly, similar to the type of flypaper traps humans use. The traps is set either by using a nectar as a reward or some glimmering droplets that attract them. Some plants have a sticky substance that holds the insect until it dies, while others have adhesive tentacles that wrap around their victims. When you see it in action, it looks quite aggressive. Again, the insect suffocates and the plant digests it.
Slip and Fall Traps: Pitcher plants evolved into a funnel shape as a way to trap food. It's easy to go in, but the shape makes it difficult to come back out. Like many other plants, they attract insects with sweetness and bright colors. What's different about these plants is that they have a slippery area around the rim caused by either a waxy substance or water droplets. Before the unsuspecting victims know it, they slip and fall down into the funnel. Once dead, the bugs get absorbed into the plant.
Suction Traps: The trap is arranged by pushing water out and therefore creating a negative pressure inside the sealed bladder. The entrance to the plant has trigger hairs, when prey gets close, the bladder instantly opens up and quickly sucks the prey in. The bladder then closes up to prevent prey from escaping so it can ingest it as a food source.

SpaceX launched a re-supply mission to the I.S.S today (June 28, 2015) Exploded
Published on Jun 28, 2015
SpaceX launched a re-supply mission to the I.S.S today. The initial launched seemed to be successful, however the rocket exploded a few minutes later in the flight. It is currently unclear what led to the catastrophic malfunction, but SpaceX and NASA are currently investigating. Thankfully no one was on-board the Craft.

CHAMBERED NAUTILUS: THE OCEAN’S JET-PROPELLED DIVER
To avoid predators by day, nautilus linger along deep reef slopes as deep
as 2,000 feet. At night, they migrate to shallower waters and cruise the reefs,
trailing their tentacles in search of food.
Its simple eyes can only sense dark and light, but the nautilus uses more than 90 tentacles—the most of any cephalopod—to touch and taste the world. A nautilus’s tentacles, unlike those of other cephalopods, have grooves and ridges that grip food and pass it to the nautilus’s mouth. A parrotlike beak rips the food apart, and a radula further shreds the food.
