A cat can cry, hiss and growl, and so can a lot of other animals. But the cat is unique: it’s the only animal capable of purring. How it accomplishes this is still a mystery.

Ancient Egyptians did not worship cats, they adored them!

The ancient Egyptians were very fond of cats. Cats were cherished members of the household. When a fire broke out in an Egyptian household, people would be more concerned about saving the cats than putting out the fire.

However, they did mummify their cats – by the thousands!

Dogs nap rather than sleep

Dogs, like all animals, are light sleepers. So while dogs seem to spend a lot of time snoozing, they’re really napping rather than slumbering. That’s why they can wake up so quickly when you call to them.

The walrus can dive as far as 350 feet below the surface of the arctic waters

For all their size, two-ton walruses are very fast swimmers, reaching a top speed of 25 miles per hour. They use their heads to break breathing holes in ice up to eight inches thick. Then they use their long tusks to widen the holes.

Vampire bats sometimes suck blood from humans

While South American vampire bats usually suck blood from livestock, they will occasionally go after humans. To survive, vampire bats must drink a teaspoonful of blood per night. Their saliva contains a powerful blood thinner that is 20 times stronger than any other blood thinner known. This thinner keeps the blood from clotting and makes it easier for the bat to drink it. This substance is used to make a drug for heart attack patients. The medicine is called Draculin.

The anglerfish uses an electric bulb as bait

The deep-sea anglerfish has long filaments with a light on the end, which dangles over the top of its head. Other fish mistake the light for food and swim into the anglerfish’s huge mouth. The anglerfish is able to produce chemicals that allow it to give off light or a glow. This is called bioluminescence. With its enormous mouth and expandable stomach, an anglerfish can swallow other fish as large as itself.

Crab fisheries are among the oldest industries in the United States. Crabbing for the blue crab was done in Chesapeake Bay as far back as the 1630s.

Some crabs use shells as trailer homes

Hermit crabs have no shell on their long, soft abdomens, so they have to find empty snail shells for protection. They drag these shells behind them like house trailers as they move about. If threatened, they retreat into the shell. Their enlarged right claw acts as a door, blocking off the opening of the shell from enemies.

Crabs use camouflage to hide from enemies

Crabs are masters of disguise. They’re sand-colored so they are hard to see on the seabed. Decorator crabs, or spider crabs, actually collect, cut, skillfully arrange, and cement algae, seaweed, and sea creatures on to their shells so that they look like part of the ocean floor.

Male fireflies attract females through a form of Morse code

The male firefly sends out a specific flash pattern of light as a signal. Some species can generate both red and green light. Fireflies, which are actually beetles, not flies, produce a chemical called luciferin that reacts with oxygen to create light.

Cockroaches are very old and very fast

The meat-eating dinosaur Tyrannosaurus rex had teeth that were six inches long, which went along nicely with its 14,000 pounds and 18-foot height. Tyrannosaurus rex was about 40 feet long. Hadrosaurs had more than 2,000 teeth. When old ones wore out, new ones quickly grew in. Hadrasaurs may have looked like today's ducks. Their name, from Latin, means "duck-billed." A Hadrosaur was about 20 feet long and six feet tall.

some very fast dinosaurs could outrun a running ostrich
