Calamansi (Citrofortunella microcarpa â this is the scientific name, notice how a scientific name is written?) is a type of citrus that is native to the Philippines. It is also known as calamondin, Panama orange or acid orange.It is very sour hence its popularity as souring agent for sinigang and sawsawan (dipping sauces). It is also one of the more common backyard trees in Philippine homes (along with papaya and guava).t is also known as calamondin, Panama orange or acid orange.

The most famous such example is Secretariat. His autopsy showed beyond a shadow of a doubt that he had an oversized heart, weighing in at 22 pounds, nearly three times that of the average thoroughbred, and more than three times that of an average non-thoroughbred horse.
this site says Secretariat's competitor, Sham, had an 18lb heart (the only Sham I've ever heard of was the Arabian Marguerite Henry wrote about, but then, I'm not a big racing fan). Yet another person claims Secretariat's lungs were 2.5x bigger than normal. This and the site that claims Secretariat's and his old rival, Sham both had double sized hearts, also claim this was a trait in that horse's pedigree and part of the bloodline.
