Many people consider sharks as predators that may attack at any time, divers possess a different viewpoint. We find these animals that are diverse ancient and lovely entrancing, also it appears like there something new to find out about sharks.

1. Sharks normally have about 45 to 50 teeth but that’s just the front row teeth. Additionally they have, on the other side of the leading row typically, up to seven replacement rows of teeth ready to move into place if a tooth is damaged or falls out. With the activity a shark’s mouth sees throughout its life, an individual might go through as many as 30,000 teeth.

2. Even though we associate sharks with big, sharp chompers, some species barely need their teeth. Basking sharks and whale sharks, two of the largest species, are both filter have numerous, tiny teeth – a whale shark may have up to 300 lines of teeth and feeders.

3. While sharks don’t use sounds to communicate, they do rely on body language. If you’re snorkeling or diving, it’s good to be aware of the body language sharks use to communicate that they’re uneasy. Hunched backs, lowered pectoral fins, sharp movements (in zig-zag or back-and-forth patterns), and diving down to touch the bottom are all good indicators that a shark is feeling uncomfortable.

4. Some big sharks have dramatically longer life-spans than small sharks. For instance, whale sharks (which normally range from 18 to 32 feet/5.5 to 10 meters in length) can live up to 100 years, while the smooth dogfish (with a typical length between 2 and 4-feet/0.6 and 1.2 meters) might just live for 16 years.

5. Whale sharks claim the title of largest shark species, and are also the largest species of fish in the world. The basking shark, the second largest shark (and fish), averages between approximately 22 and 29 feet/ 7 and 9 meters. Pygmy Ribbontail Catsharks are perhaps the smallest, at about 6 to 7 inches/ 17 to 18 centimeters . Other small species include the Dwarf Lanternfish and the Spined Pygmy Shark , both of which are roughly the same average size as Pygmy Ribbontail Catsharks.

6. Sharks have of giving birth to their own young, complicated and diverse ways. Some lay egg cases, which have been nicknamed “mermaid’s purses” and sometimes wash up on beaches. However, live birth is given by a lot of sharks, along with a female might give birth to as several as 48 puppies in one litter.

7. There are some estimates that for each person people yearly kill 25 million sharks. There are 201 sharks on the “Red List” of endangered species, published by by the International Union for Conservation of Nature (IUCN). While estimates vary as to how many sharks are killed, either for harvesting fins, hunting or in incidental “bycatch” in fishing equipment, the figures are all dramatic, ranging from 70 to 100 million. Sharks are an essential component in marine environments, and their fast dwindling numbers are a main source of concern among conservationists. Movements like Project AWARE are bringing attention to and fight the over exploitation of sharks.

8. Research has helped break the myth that sharks are attracted to the color yellowish – in fact, they probably can’t see colour at all. The old saying “yum yum yellow” was rooted in the idea that sharks could see and were more likely to approach divers wearing the color. Because sharks’ eyes were found to lack or have minimal color-sensing cells , it seems to make more sense that what actually draws attention is the contrast in colors, rather than the color itself.

9. Sharks live in all seven of the world oceans, but they’re maybe not limited exclusively to wide-open bodies of salt water. There are species that can survive in mixed salt- and freshwater environments like estuaries and watersheds that connect to an ocean, while other species can live in completely fresh water. Bull sharks can survive in both saltwater and freshwater, and have been known to frequent the river.

10. Sharks are a living link with the period of the dinosaurs. Scales and teeth dating from more than 400 thousand years past offer hints about how those early ancestors appeared to us. However, what we consider as “ sharks that were modern appeared around 100 million years ago. The frilled shark, which can be uncommon but still in being, has developed almost no over the millennia and is regarded as one of the finest examples of what sharks that were early appeared to be.

Animals come in all shapes, sizes and colors. Some are beautiful, majestic and endearing. Others are downright nasty and repugnant. Wouldn’t it be fun to try and narrow down the worst looking of the bunch? Here is my unofficial list of the top ten ugliest animals in the world.

10. Sphynx Cat

This cat is hairless and hideous. Despite its horrible looks, it is known as quite loving towards its human owners. They are also said to have fantastic personalities.

9. Warthog

Found in Africa, the warthog looks like a pig with horns. Warts cover their large flat heads.   Even though these warts are for protection, they are not aesthetically pleasing to the eye.

8. Baird Tapir

The baird tapir is the largest mammal found in Mexico and South America. As if a nose and upper lip that stick straight into the air isn’t ugly enough, they also have four toes on the front feet and three toes on the back.

7. Proboscis Monkey

The proboscis monkey is on the endangered species list. Their long, protruding noses are used to honk in a form of communication with other monkeys.

6. Celestial Eyed Gold Fish

Goldfish remind us of a small, cute pet fish. This is hardly the case with the celestial eyed gold fish. With eyes larger than their stomachs, they can be quite frightening.

5. Aye-Aye

Found in Madagascar, this is the largest nocturnal primate.   It taps on trees to find food, similar to the woodpecker. The aye-aye is on the endangered species list because it is thought to be bad luck and killed on sight.

4. Star Nosed Mole

The star nosed mole is located in parts of the United States and Canada. It has a star shaped nose with 22 fleshy tentacles reaching out. This absurd nose is so sensitive, it can even sense electricity.

3. Tarsier

As the smallest known primate, the tarsier is the size of a human hand. They like to jump from tree to tree to catch flying birds. If captured, this animal is known to kill itself due to the stress.

2. Naked Mole Rat

Also known as “sand puppy,” the naked mole rat is found in East Africa. They have large protruding teeth used for digging. The naked mole rats eyes are small and narrow, perfect for its life underground.

1. Blobfish

Found in the deep waters of Australia, the blob fish is the ugliest known animal in the world. It is rarely seen by humans because it lives in the deepest parts of the ocean. Due to its body make up, the blob fish can float above the sea floor without wasting any energy.

10. Hobo Spider

Hobo spider is a brown colored spider with hairy legs. The bite of this spider can kill the tissues around it and takes very long to heal, leaving visible marks behind. Also, it can cause sharp headache, which would require medical aid.

9. Yellow Sac Spider

8. Goliath Birdeater Tarantula

This is one of the biggest and most deadly looking spider, which can attack a whole bird, as suggested by its name. its bite can cause severe pain and swelling in human beings.

7. Brown Recluse

Brown Recluse, a species common in America. This spider frequents dark corners and its bit can result in symptoms such as fever, vomiting, shivering and redness and swelling around the sting.

6. Mouse Spider

Mouse spider is a tough species which can survive in diverse climatic conditions, though they are commonly found in Australia. The color difference can help you distinguish male spiders (brown) from the females (black). These spiders bite once they sense any danger and can cause fever, vomiting and breathing problems on biting.

5. Red Back Spider

Another spider native to Australia, Red Back Spider is one of the most elegant looking yet deadly spiders in the world. The venom of this spider is full of neurotoxins, which makes its bite fatal for human beings. Its bite can lead to vomiting, pain, sweating and muscle weakness.

2. Black Widow Spider

Featuring next on the list of 10 most poisonous spiders in the world is the notorious black widow spider, which is found in the hot regions of USA. Occurring in black and sometimes in brown color, this spider has a neurotoxin called latrotoxin in its venom, which is potent enough to kill human beings.

1. Brazilian Wandering Spider

The most poisonous spider in the world is the Brazilian Wandering Spider, which inhabits Central and South America. PhTx3 is the neurotoxin found in the venom of this spider, which has the ability to cause paralysis and death due to asphyxiation.
