How Piranhas are the most dangerous fish for human beings?

Piranha 

Piranha is an aggressive fish and a meat eater. Because of its aggressiveness, it is known as a dangerous fish amid many people. It is even known as a great white shark. There are nearly 25 species of piranha. Piranhas are sharp toothed fish having deep bodies. You will find their bodies flattened on both of their sides. The color of their bodies is usually olive green and red belly. They are carnivorous fish that usually grow up to 15 to 25 cm. 

There are a few fishes that have been seen in a size of 40 cm long too.Their mouth is open. Teeth of these species are visible. Red piranha is the most famous fish in piranha family that grows up to nearly 30 cm.

The deep sea fish called piranhas is found all over South America and are fresh water fish. Such fish prefer to live in shallow water however may be even found in the deeper water of the river. It has been observed that the attack of such fish is rare on human being but very dangerous. It has been even also observed that swimming in piranhas infected water is very risky at the time of especially drought season. It is because during drought season, there is food shortage for piranhas and hence they become violent and attack on human being.

Piranhas

Piranhas have the similar sensory capability, which sharks have. They may sense blood from distant place. Such fishes are risky if any person enters into piranha infected water having a scratch. Group of such fish may turn into a horse within some time if attacked. But such stories do not have any proof however they attack severely on the smell of blood. Piranhas are mainly found in Guianas, Amazonian river and Paraguayan river. These fish prefer living in groups but can be found in small groups too. We can take an example to prove how piranhas are dangerous sea animals and fish for human being. Once in a South American Jungle river, a man was fishing. He suddenly fell from his canoe hence he shouted for help. Another canoe came there for his help. Even if his hands were hanging on the canoe, he was dead. From that man’s waist down, piranha had left just a skeleton.

Life Cycle of Tiger Shark

The tiger shark (Galeocerdo cuvier), is a species which belongs to requiem shark and it is the only member of the genus Galeocerdo. Tiger sharks are large in size and grow up to a size of about 5 m in length. These sharks mature when they reach up to a length of (2 to 3 m). These sharks are found in tropical and temperate oceans. It is most common around central Pacific islands. The Tiger Shark got this name because of the black, tiger-like markings on its body. The tiger shark is considered as one of the most dangerous sharks to humans. However, the research says just opposite to what people feel. The attack rate is very low according to the research. The great white shark is considered to be the first on the basis of human attack. But, these sharks are in the list of threatened species.

Tiger Shark Diet

The tiger shark likes to move alone. They hunt mostly at night. These sharks feed on wide range of prey, such as  squids, crustaceans, fish, seals, birds, smaller sharks, sea snakes, turtles and dolphins. These sharks have characteristics that they can survive on wide range of food and this is the reason they are also called as the most adaptable of all shark species.

Tiger Shark Reproduction

These species reach sexual maturity when it grows up to a size of (2.3 to 2.9) meters in male and (2.5 to 3.5) meters in female respectively. The female tiger sharks are known to mate once every three years. The tiger sharks breed by the process of internal fertilization. During mating, the male inserts its one of the claspers into the female's cloaca. The males use their teeth to hold the female during the mating process. The tiger shark is the only species in their family that is ovoviviparous. It means their eggs hatch internally and the young are born live when fully developed. The baby tiger sharks are (51 to 76) cm in length. The life span of these species is not known accurately but most often they can live longer than 12 years.

External Parasites in Cat

Cats have been petted since as early as 3500 BC. Egyptians domesticated wild cats from Africa. These wildcats then became the most treasured pets. Cats have fascinated the literary stalwarts like T. S. Eliot who wrote a collection of poems called “Id Possum’s Book of Practical Cats”. This collection was about feline psychology and sociology. Considering the fascination for cats that we humans have, we also need to take care of them as we pet them. Cats need to be taken care of though it is a known fact that they are very hygienic. Cat care and cat health is of utmost importance if you have a pet cat. From a young age, cats get infested with external parasites. Most common of them are ticks on cats, lice, fleas, or cat mites. This infestation causes skin irritation. It is also a reason for cat illnesses.

Cat Care

There are many safe anti-parasitic treatments that can be used on a long-term basis to protect your pet cat from the external parasites. Parasites are organisms that feed on other creatures to survive. Generally, among cats they live on and feed on cat’s blood. Detecting internal ones are difficult. But, when you have a close look at the skin and fur you can detect and uncover their traces like ear mites and fleas. 

Worms are internal parasites in cats.

Ear mites:

They take residence in the cat’s ear canals. As they feed on them, they create an intense itching. It scratches behind her ears and violently shakes her head regularly. When you peep inside her ears, you will see dark flecks that look like coffee grounds; these are actually mites’ droppings. If you suspect ear mites in cats, contact a veterinarian.

Coccidia:

Coccidia are microscopic parasites. They live within the lining of the intestines in the cells. When they are left untreated, cats become weak and dehydrated. Coccidiosis is treatable. But, drugs do not kill these parasites, but inhibit their reproduction. Elimination of these parasites from the intestine is very slow.

Ringworm:

It is not a worm in the true sense, but rather the name for a type of fungus. This fungus is related to the fungus that causes athlete’s foot in humans. It causes discomfort, but is very contagious to cats and humans too. When left untreated, it weakens the immune system. It leaves your cat to other diseases too.

fleas in cats

Fleas:

They are the most infamous external parasites in cats. They eat no more than a drop of blood each. A flea can cause anemia and even death in cats. It sucks the life from the cat and the fleas transmit tapeworms. Just a few cat fleas can cause discomfort in cats, especially if she is allergic to fleabites. The best way is to prevent fleas before they attack your cat.
