The tiger beetle runs so fast, it can no longer see where it is going. It actually has to use antennae to avoid obstacles.
The largest mouth in the world belongs to the bowhead whale. It can measure up to 16 feet long, 13 feet high and 8 feet wide. Its tongue alone weighs almost two thousand pounds.
Intense snake hunger can cause snakes to actually digest their own heart muscle; however, immediately following a nutritious meal, snake hearts can quickly rebuild themselves.
Some marine birds, like the penguin, have a supraorbital gland located just above their eyes that can remove sodium chloride from their bloodstream. It works just like our kidneys, removing salt, which allows the penguin to survive without access to fresh water. The penguin excretes the salt byproduct as brine through its bill.
The highest-flying bird in the world is the Ruppell’s vulture. There is confirmed evidence of one flying at an altitude of 37,000 feet above sea level during which it collided with an aircraft.
Explanation: How many moons can you see? The best answer is five: four orbiting Jupiter and Luna orbiting Earth. This multi-moon picture was possible because Earth’s Moon moved directly in front of Jupiter last week. The featured image is a series of exposures near alignment taken from Westchester, New York, USA. The sunlit crescent of Earth’s Moon, on the lower left, is overexposed, while the Moon’s night side, on the upper right, is faintly illuminated by Earthshine. Lined up nearly vertically above our Moon, listed from bottom to top, are Jupiter’s bright Galilean satellites: Ganymede, Io, Callisto, and Europa. Callisto, Ganymede, and Io are larger than Earth’s Moon, while Europa is only slightly smaller. NASA’s robotic spacecraft Juno is currently orbiting Jupiter and has made close passes near three of these moons.
