Video - Mind-Blowing Facts: Stars, Sharks, Butterflies, Jellyfish & Lightning!

"There are more stars in the universe than grains of sand on all the world's beaches. With billions of galaxies each containing millions or even billions of stars, the cosmos is unimaginably vast." "Sharks have been around longer than trees. Sharks first appeared about 400 million years ago, while the first trees evolved around 350 million years ago, making sharks one of the oldest species on Earth." "Butterflies taste with their feet. These insects have taste sensors on their feet, allowing them to taste any surface they land on and determine if it’s a suitable place to lay eggs." "Jellyfish have been around for at least 500 million years, possibly even longer. They have survived five mass extinctions, making them one of the oldest living creatures." "A bolt of lightning contains enough energy to toast 100,000 slices of bread. Each lightning strike can reach temperatures of 30,000 K (53,540°F), which is five times hotter than the sun's surface."
