Shark SVG belongs to the type of chord animals, the class of cartilaginous fish, shark superintendent (Latin Selachii).
How does a Shark SVG look like?
Due to the species diversity, the length of sharks is very different: small bottom sharks barely reach 20 cm, and the whale shark grows up to 20 meters and weighs 34 tons (average sperm whale weight). The skeleton of the shark has no bones and consists only of cartilage. The streamlined body is covered with scales with pronounced relief protrusions, the strength of which is not inferior to the teeth, and therefore the scales of the shark is called “skin cloves”.
The shark’s respiratory organ is the gill slots in front of the pectoral fins.
The shark’s heart maintains too low a blood pressure, so to stimulate blood flow, the fish should be in motion as often as possible, helping the heart with continuous muscle contractions. Although some sharks feel great lying on the bottom and pumping water through the gills.
The Shark SVG does not have the swim bladder that all bony fish have.
Therefore, the buoyancy of the shark is provided by a giant liver, which makes up almost a third of the body weight of predatory fish, low density of cartilage and fins.
The stomach of the shark is very elastic, so it can hold large amounts of food.
For digestion of food concentration of hydrochloric acid in the gastric juice is not enough, and then the sharks turn the stomach inside out, freeing it from undigested excesses, and interestingly – the stomach does not suffer from many sharp teeth.
Sharks have excellent eyesight, exceeding the sharpness of the human in 10 times.
Hearing is represented by the inner ear and captures low frequencies and infrasounds, and also provides a balance function for predatory fish.
Sharks have a rare sense of smell and can smell the smells coming from the air and water.
Blood odor is captured by predators at a ratio of 1 to a million, which is comparable to a teaspoon diluted in a swimming pool.
Shark SVG speeds typically do not exceed 5 to 8 km/h, although the predator can accelerate to almost 20 km/h when it smells prey. Heat-blooded species – white shark and macho shark – cut through the water column at speeds of up to 50 km/h.
The average life expectancy of a shark is no more than 30 years, but sand kathrans, whale and polar sharks can live for more than 100 years.
The structure of the predator’s jaw depends on the lifestyle and food consumed. The shark’s teeth are long, sharp and cone-shaped, and they can easily open up the flesh of the prey.
The Shark SVG family has flat and sharp teeth that allow them to tear up large quantities of meat into pieces.
The whale shark, whose main diet is plankton, has small teeth up to 5 mm long, although their number can reach several thousand.
Horned sharks, which feed mainly on bottom food, have sharp, small front teeth and a back row of large crushing teeth. As a result of grinding or falling out, the teeth of predatory fish are replaced by new ones growing on the inside of the mouth.
