Today I am going to tell you each and everything about sharks; from their body structure, to eating habits, to facts and myths related to them. So let’s begin with something general about them.
Sharks are the members of Chondricythyes class that have full cartilaginous skeleton and a streamlined body. Rays and skates also belong to the same class, so sharks are very close relative of rays and skates. Shockingly most of them relate to rays more rather than other sharks. They like all other fishes, respire through gills rather than through lungs as mammals do. Sharks have canine teethes that aren’t attached to the jaw, rather are embedded in the skin. Their teeth are the most surprised beauty that God have given to them. Sharks physical structure is quite varying. Sharks can be too small just 22 centimeters long such as pygmy shark or can be too large up to 13 meters such as white shark. Until now, more than 360 species of these sharks have been discovered. The most notable of all is Bull Shark.
They have cartilaginous skeleton which is very light and quite flexible than bone. Their skin is often guarded against parasites and other damages because of dermal denticles covering. All sharks have streamlined bodies though few of them have wide fins in the end. So as with other fish species in addition they swim swiftly though they’ve bulky bodies.
Sharks teethes are not connected to the jaw but they are suspended into the flesh of their mouth. This may be because they need more piercing power when attacking their prey. Interesting fact about sharks teethes is that in an average, single shark may loose 30,000 teeth in a lifetime. Sharks have tails that provide them speed and acceleration. The arrangement of the tail varies from shark . Shape of the tail provides shark the ability to survive and prey in different environments.
Sharks respire through gill slits that are located just next to head prior to the pectoral fin. They also have spiracle, a modified gill, right over the head though which they intake water while respiring. This spiracle plays important role for the bottom dwelling sharks in which the oxygen concentration in the water is quite less. Sharks eyes are covered with a tissue called tapetum lucidum that made them ideal for marine atmosphere. Sharks life span might be from 20 to 30 years.
They could eat anything from small fishes, crabs, turtles, big fishes, and even other small sharks. They prey in groups whether they are preying on the surface of the water or at the bottom. Their technique to assault may vary from species to specie. Some sharks swathe their prey and kill the weak ones while other sharks prey using hidden attack technique. But one thing is common to them all. Yes and this aggressiveness have encouraged them to humans too. Sharks have olfactory glands that let them feel even a 1 part million of blood in the water. They’ve hearing power too.
Reproduction in shark is very seldom observed. While some sharks reproduce by curling around the female shark whereas other shark the big ones often mate swimming parallel to each other. An individual can easily distinguish between man shark and female shark. Males have altered pelvic. Sharks produce pups either straight or shield them using egg cases unlike eggs laid down by other fishes. Sharks can even mate without needing any male partner.
This all told about their arrangement, eating habits and reproduction, let us know move towards some rumors connected with them. In direct words, sharks don’t prey humans though few shark species are harmful for humans. They don’t like to feed on people. So then what about the stories linked to the sharks attacking the humans? Sharks attacks on us only if they feel being trapped or when someone comes their way. Usually sea-divers and water surfers are the victims of shark attacks. Sharks like to ride on high tides and hence often attacks surfers coming their way. We people often think that white sharks are the most peculiar underwater creatures but some divers had reported to go as close as to them without a fear of being getting hit by white sharks however few precautions are needed.
Get yourself out of the false stories associated with sharks and show your respect towards them. Shark killing was increased in past 50 years. Some of the shark species have gone extinct. They are of huge importance to us and temperament. Nature has created every creature with pre-defined targets and we should collaborate with character as much as possible. That’s it!
