The Inside Dope about Sharks.
Gonna sing “ just keep swimming, just keep swimming’ when I’m actually swimming next to the sharks precisely Megalodon ( sadly they don’t actually exist anymore). I know you might be thinking that swimming next to sharks is a worse thing to do but hey! Stop claiming that sharks attacked people every year, they rarely attack humans and would much rather feed on fish and marine mammals. Unlike us we do have hands to touch to sense it. The only thing that the shark could do is by biting them to sense it. Here are some senses:
- Vibration sensors — sixth sense
All sharks have a ‘sixth sense’ that helps them hone in on prey during the final phase of attack: the ‘amupllae of lorenzini’ are found on sharks’ snouts and can sense the electric fields emitted by animals in the surrounding water. I read an article saying that sharks, use Earth’s magnetic fields to guide them like a map for their long-distance forays across the sea.
2)Smell/Sight
At a distance of 0.5 km, a shark can smell blood in the water and follow a trail back to the source. It can detect one part of fish extract in 25 million parts of seawater. According to Science daily, sharks are colored blind, although they have a function over a wide range of light levels, they only have a single long-wavelength-sensitive cone* type in the retina and therefore are potentially totally color blind.
3)Electrical sensor
Electroreceptor organs that allow the shark to sense electromagnetic fields and temperature shifts in the ocean. Sight At night their eyes glow in green. They have a ‘tapetum lucidum’. A reflective layer of shiny cells that lies behind the retina. This improves vision in low light conditions, allowing nocturnal and deep-water species to hunt effectively.
Sharks are crucial source for aquatic ecosystems but biotech companies are utilizing shark’s squalene to produce Covid-19 vaccine. There are actually some alternatives of the vaccines like you can derived it from the plants instead from this creature! The least we can do this stay home and take precautionary methods to avoid getting Covid-19 and also save sharks!
