Shark Facts

Sharks are fish. However, they do not have bones like other fish. Their skeleton is made of cartilage. This is the same bendable material that is in your ears! They also do not have a swim bladder, the air filled balloon-like organ that keeps most fish upright. Sharks have gill slits but no gill-cover, which is common to most bony fish. Because they have no swim bladder to keep them buoyant, sharks sink when not swimming. Shark's bodies are heavier than water and most sharks are constantly on the move. By moving forward with their mouths open, sharks move water across their gills for breathing. The larger species produce live young that are fully formed, miniature versions of their parents. Mother sharks offer no food or protection for their young. Young sharks do have a fighting chance, though, as they are born with a full set of teeth and the ability to swim.. The list of amazing and funny facts about different kind of sharks are given below:

* The Whalefish Shark is the largest fish in the ocean. It can reach up to 50 feet and weigh about 30 tons. The whalefish eats plankton. It swims in warm waters near the equator. It filters meals as it swims with its mouth open. It is not threat to humans
* Just as humans rule the land, sharks rule the sea! Many people fear sharks, because they hear stories about sharks killing and eating humans. Actually, most sharks are not dangerous!
* Sharks never get cancer! Their cartilage is used in being studied with the hope of developing anti-cancer drugs.
* The dwarf shark is as small as your hand, while the whale shark can be as large as a school bus!
* A shark may grow and use over 20,000 teeth in its lifetime!
* Sharks never run out of teeth. If one is lost, another spins forward from the rows and rows of backup teeth.
* Sharks even eat other sharks. For example, a tiger shark might eat a bull shark, a bull shark might eat a blacktip shark and a blacktip shark might eat a dogfish shark!
* The whale shark is up to 46 feet (14 m), weighing up to 15 tons. The average size is 25 feet (7.6 m) long It is the largest fish in the world. Females are larger than males (like most sharks).
* It has been estimated that whale sharks may live up to 100 - 150 years.
* A shark's hunger can be satisfied with one good meal. The meal can last a long time because a shark uses little energy to swim. Some sharks hold food in their stomachs without it being digested. If they eat a big meal, it can last three or more months!
* A shark's hunger can be satisfied with one good meal. The meal can last a long time because a shark uses little energy to swim. Some sharks hold food in their stomachs without it being digested. If they eat a big meal, it can last three or more months!
* Sharks have existed for over 350 million years. They evolved over 100 million years before the dinosaurs did. This was long before people evolved.

Amazing Animal Senses

Animals have developed amazing adaptations to their environments. Many different types of energy & senses exist in the environment, some of which humans cannot detect. Here are some examples of how some animals sense the outside world.


* Can detect small movement through 5 cm of earth.
* Can see polarized light.


* Can detect warmth of an animal from about 16 cm away using its "nose-leaf".
* Bats can also find food up to 18 ft. away and get information about the type of insect using their sense of echolocation.


* Can see light between wavelengths 300 nm & 650 nm.
* Have taste receptors on their jaws, forelimbs and antennae.
* Worker honey bees have a ring of iron oxide in their abdomens that may be used to detect magnetic fields. They may use this ability to detect changes in the earth's magnetic field and use it for navigation.
* Can see polarized light.


* Has taste receptors on its feet.
* The butterfly has hairs on its wings to detect changes in air pressure.
* Using vision, the butterfly Colias can distinguish two points separated by as little as 30 microns.


* Has hearing range between 100 and 60,000 Hz.
* Olfactory membrane about 14 sq. cm. For comparison, humans have an olfactory membrane of about 4 sq. cm.


* The eyes of the chameleon can move independently & can see in two different directions at the same time.


* Can detect movement as small as 2,000 times the diameter of a hydrogen atom.


* Has hairs on claws and other parts of the body to detect water current and vibration.
* Many crabs have their eyes on the end of stalks.


* Can hear using their legs; sound waves vibrate a thin membrane on the cricket's front legs.


* Has olfactory membrane up to 150 sq. cm.
* Can hear sound as high as 40,000 Hz.


* Like bats, dolphins use echolocation for movement and locating objects.
* Can hear frequencies up to at least 100,000 Hz.


* Eye contains 30,000 lenses.


* Entire body covered with chemoreceptors ( taste receptors ).


* Has hearing range between 1 and 20,000 Hz. The very low frequency sounds are in the "infrasound" range. Humans cannot hear sounds in the infrasound range.


* Can see a 10 cm. object from a distance of 1.5 km.


* Have a "lateral line" system consisting of sense organs ("neuromasts") in canals along the head and trunk. These receptors are used to detect changes in water pressure and may be used to locate prey and aid movement.
* Some fish can see into the infrared wavelength of the electromagnetic spectrum.

Fish ( Deep sea )

* Only have rods in the retina: 25 million rods/sq. mm. Perhaps they need this high density of photoreceptors to detect the dim biolumninescence that exists in the ocean depths.

Fish ("Four-eyed Fish" Anableps microlepis)

* Can see in air and water simultaneously. Each eye is divided by flaps, so there is one opening in the air and one in the water.


* Eye has a flicker fusion rate of 300/sec. Humans have a flicker fusion rate of only 60/sec in bright light and 24/sec in dim light. The flicker fusion rate is the frequency with which the "flicker" of an image cannot be distinguished as an individual event. Like the frame of a movie...if you slowed it down, you would see individual frames. Speed it up and you see a constantly moving image.
* Blowflies taste with 3,000 sensory hairs on their feet.


* Has an eardrum (tympanic membrane) on the outside of the body behind the eye.


* Normal vision for people is 20/20. A hawk's vision is equivalent to 20/5. This means that the hawk can see from 20 feet what most people can see from 5 feet. (Scientific American, April 2001, page 24)


* Can hear frequencies between 1,000 and 100,000 Hz. By comparison, we humans can hear frequencies between 20 and 20,000 Hz.


* Attracted to host by human body odor ( especially the foot odor), carbon dioxide, body heat and body humidity.


* Retina contains 20 million photoreceptors.
* The eye has a flicker fusion frequency of 70/sec in bright light.
* The pupil of the eye is rectangular.


* Has a flat cornea that allows for clear vision underwater. Penguins can also see into the ultraviolet range of the electromagnetic spectrum.


* Tongue contains 15,000 taste buds. For comparison, the human tongue has 9,000 taste buds.


* With eyes mounted laterally on their heads, pigeons can view 340 degrees...everywhere except in back of their heads.
* Can detect sounds as low as 0.1 Hz.


* Tongue contains 17,000 taste buds.


* Has hearing range between 1,000 and 90,000 Hz.


* Each eye can move independently.


* Can detect air moving at only 0.072 km/hr with special hairs on its pincers.
* Can have as many as 12 eyes.


* Has specialized electrosensing receptors with thresholds as low as 0.005 uV/cm. These receptors may be used to locate prey. The dogfish can detect a flounder that is buried under the sand and emitting 4 uAmp of current.
* Some sharks can detect fish extracts as concentrations lower than one part in 10 billion.
* Some sharks sense light directly through the skull by the pineal body.


* The tongue of snakes has no taste buds. Instead, the tongue is used to bring smells and tastes into the mouth. Smells and tastes are then detected in two pits, called "Jacobson's organs", on the roof of their mouths. Receptors in the pits then transmit smell and taste information to the brain.
* Snakes have no external ears. Therefore, they do not hear the music of a "snake charmer". Instead, they are probably responding to the movements of the snake charmer and the flute. However, sound waves may travel through bones in their heads to the middle ear.
* Snakes have no moveable eyelids. Instead, they have a clear, scale-like membrane covering the eye.


* Many spiders have eight eyes.
