Scientists propose raising the hurricane scale
Scientists are proposing to raise the level of the hurricane scale to accommodate stronger storms. The inspiration for this proposal came from the recent extreme storm on the US west coast. Atmospheric rivers, which can bring twice as much water flow as the Amazon River, have become a deadly phenomenon in recent years. The existing hurricane scale, which only goes up to category 5, fails to adequately categorize and warn about stronger storms. Scientists argue that raising the scale to at least category 6, or even up to 11, would provide more accurate information and better prepare people for more severe weather conditions.
Sharks use their spiracles to breathe without swimming
Most sharks have to swim to get oxygen, but benthic sharks are able to pump water through their spiracles, small holes behind their eyes and over their gills so they can breathe without swimming.
Sharks rely on their sense of smell and electro-receptor organs
Sharks as a group have poor vision and instead rely on their sense of smell and special electro-receptor organs that can sense electromagnetic fields.
Counting growth rings can accurately estimate the age of sharks
The age of most sharks can be accurately estimated by counting growth rings on their vertebrae.
