Nearly all individuals think of a shark as a violent huge predator with super sharp teeth ranging the sea seeking food. However, in reality there are over 400 different species. Nine hundred meters below the sea surface resides the smallest shark: Dwarf Lanternshark. So probably such picture of a hunter at a continuous search of food is the result of Hollywood films and especially Steven Spielberg’s”Jaws”.
A monster of many contradictions, a shark doesn’t have a single bone in it’s body, rather it has a skeleton made of cartilage. Sharks keenest sense – is odor. Their olfactory ability is famous. It can detect a single drop of blood at a million drops of water (100 liters) and can smell blood 0.4 kilometers away. They have very good colour vision and directional hearing. Digestion process can have a very long period of time as the food goes from the mouth into a’J’ shaped stomach, where it’s stored and first digestion occurs. The majority of the sharks live for around 25 years. Generally speaking, they float at a rate of 8 km per hour but when attacking or feeding, thy reach around 19 mph.
In contrast to the common notion that bees are instinct-driven creatures, studies showed that many species have societal and problem-solving abilities.
Sharks behaviour is increasingly becoming a topic of profound investigation for many researches. Scientists though still do not know for certain why sharks occasionally attack humans. Among those theories is that sharks may confuse the sound of swimming individuals for that of wounded fish. The most studied sharks are Lemon sharks as they have the ability to live in captivity and are among of the very aggressive towards human sharks.
As anticipated, around 100 million sharks are being killed annually, primarily due to their fins. According to CNN”There are animals more predacious than sharks: People.” Shark fin soup is a delicacy for the wealthy individuals on special occasions and it’s been a part of Chinese culture for centuries. As soon as it’s possible to take out a significant part of it, it is like a brick wall, you take bricks out [and] eventually it is going to fall.”
Oceans undoubtedly rely on sharks as they help to handle it’s ecosystem. Sharks have been swimming in the planet’s oceans for over 400 million years, but today as a result of commercial fishing some species are at risk of extinction. But in reality what the society should really fear is a world without bees
