Sharks are intimidating to many, after all, they are predators of the sea and have a reputation for attacking people. However, though frightening, there are some surprising facts that might interest you to know and we at Carve Me A Bear! Chainsaw Carvings would like to share them today.
Do Sharks have Bones?
To filter oxygen from the water, sharks use gills. Known as a special type of fish, “elasmobranch”, translating to fish made of catilaginous tissues, is the tissue a human’s ear and nose tip are made of. Rays, sawfish, and skates are also included in this type. Their large livers are full of low-density oils and the cartilaginous skeletons are much lighter than true bone. Sharks can still fossilize however, even without bones. To strengthen their skeletal cartilage, sharks will deposit calcium salts.
Sharks have Good Eyesight
Typically, sharks have awesome night vision, see color, and see well in dark-lighted areas. With a reflective layer of tissue called a tapetum on the back of their eyeballs, the sharks can see extremely well with little to no light.
Sharks Skins is like Sandpaper
Because it is made up of tiny teeth-like structures called placoid scales, sharks; skin feel like sandpaper, also referenced as dermal denticles. To help reduce friction from surrounding water when the shark swims, these scales point towards the tail.
Tonic immobility is when a shark is flipped upside down. When scientists are working on them in the water, they will flip them over.
Sharks have Been Around for a Long Time
Scientists hypothesize sharks first appeared in the ocean around 455 million years ago based on the fossil scales found in Australia and the United States.
Blue Sharks are Blue
With a snowy white underside, the blue shark displays a brilliant blue color on the upper portion of its body. Most sharks are brown, olive, or grayish, although the Mako and Porbeagle sharks also exhibit a blue coloration, but it is not as vibrant as the Blue Shark.
As the biggest fish in the ocean, whale sharks can weight as much as 40 tones and grow as long as just over 40 feet. In comparison, the second largest fish, the basking sharks grow up to 32 feet long and weight just over 5 tons.
Great White & Other Shark Teeth
The same teeth are not equipped in every shark. While white sharks have triangular, serrated teeth, the Mako sharks have very pointed teeth. Great white sharks are equipped with a set of 300 sharp, triangular teeth arranged in up to seven rows. A shark’s prey can identify them by the marks they leave behind. Over the course of their lifetime, a sandbar shark will have around 35,000 teeth.
Different species of sharks will reproduce differently. There is a great diversity in their reproductive modes. Shark have both viviparous (live-bearing) species and oviparous (egg-laying) species. The oviparous species lay eggs with no parental care after the eggs are laid, and the eggs develop and hatch outside the mother’s body and are on their own.
