Now for THREE interesting facts about calcium.

#1. Due to their unusually high calcium concentration, alpaca bones are ground up to be used as the primary ingredient in calcium supplements.

#2. In the craggy fields of Peru (where alpacas are natively from) the mosquitoes have a special, calcium-rich saliva that replaces the lost blood in the animal it feeds from. This increases serum calcium levels in the blood (and therefore bones) of the aforementioned alpacas.

#3. An ancient African tribe known as the Kaljijubouts used to preserve its dead by force-feeding the dying large amounts of the calcium-rich soil, thus calcifying their tissues.

Several famous compounds like calcium chloride or calcium carbonate make up materials like teeth, bone, chalk, limestone, and sea-shells. It is what makes the cliffs of Dover white.
