Whale Fun Facts Sperm Whales have the largest brain on the planet. It may weigh 20 pounds. The fin whale is one of the fastest whales. They can swim over 20 miles per hour for short periods. The blue whale is the largest whale. They may grow up to 100 feet and weigh as much as several elephants. The harbor porpoise is one of the smallest whales. They grow to only about 5 feet in length. Whales can't breathe through their mouths. The mouth is connected directly to the stomach. They breathe through their blow holes, which go to the lungs.A sperm whale can hold its breath for at least an hour. The voice of the blue whale is one of the deepest voices on the planet. It is so powerful that it can travel for perhaps a hundred miles underwater. A new born baby blue whale may weigh two tons and be 25 feet long. Some whales do not have teeth. There is a toothed whale which only has two teeth.
The word 'elephant' comes from the Greek word eléfas, meaning 'ivory'. Elephants are the largest terrestrial animals on earth, measuring about 10-13 feet in height and 11,000-15,400 pounds in weight. They also have the largest brains. But, you will be surprised to know that these massive animals are quite gentle and have no natural enemies.
The decrease in population of elephants is mainly because of habitat loss and human poaching for ivory and flesh. Under Wildlife Conservation, the 'African Elephant Conservation Act of 1989' and the 'Asian Elephant Conservation Act of 1997' have been passed in order to conserve the natural habitats and protect them. Strict laws have been enforced to stop trading of elephants and collecting ivory. Tusk, which is another extraordinary feature of an elephant, is nothing but the second upper incisor that grows continuously. Tusks of an African elephant can grow up to 10 feet long and can weigh up to 90 kilograms, whereas tusks of an Asian elephant vary according to gender - female shows short or no tusk while the male has lean tusks, which may be of 10 feet long and around 40 kilograms weight.
As the oil spill coats Gulf Coast beaches, rescuers are hatching a daring plan to save as many as 70,000 sea turtle eggs from the disaster. Each year, thousands of newly hatched sea turtles scramble from their nests in the Florida Panhandle's sandy beaches and Alabama coasts into the water. With those waters fouled by oil and chemical dispersant, a whole generation of sea turtles could be harmed or even destroyed.
