Today is National Trivia Day. It is observed across the United States each year on January 4. We observe trivia day, everyday here.
A shrimp’s heart is in its head –
along with other vital organs such as their stomach and ventral nerve cord. If that wasn’t interesting enough (well to me anyway,) due to the nature of their open circulatory system, shrimp have no arteries so their organs just float around in blood.
Sloths can hold their breath longer than dolphins.
Dolphins need to come up for air every 10 minutes, but by slowing their heart rate, sloths can actually hold their breath for 40 minutes.
Supermarket apples can be a year old.
Farmers often pick apples in the fall, cover them in wax, hot-air dry them, and then put them in cold storage. This keeps them edible and ready to sell for 6 to 12 months!
Cat urine glows under a black light.
Black lights can be used to detect any body fluids, but cat urine glows particularly bright under ultraviolet light primarily because it contains the element phosphorus. Why you are spending your day hunt for cat urine is another matter entirely.
So it appears trivia is not so trivial to me.
