[2] [3] Estimates on the number of Earth's current species range from 10 million to 14 million, [4] with about 1.2 million or 14% documented, the rest not yet described. [5] However, a 2016 report estimates an additional 1 trillion microbial species, with only 0.001% described. [6]
Stuffed toys are made from a range of materials. The earliest were created from felt, velvet, or mohair and stuffed with straw, horsehair, or sawdust. [5] [20] Following World War II, manufacturers began to adopt more synthetic materials into production, [5] and in 1954, the first teddy bear made from easily washable materials was produced. [2]
It was sports organizations that initially first thought of using animals as a form of mascot to bring entertainment and excitement for their spectators.

When the original name is changed, e.g., the species is moved to a different genus, both codes use parentheses around the original authority; the ICNafp also requires the person who made the change to be given. In the ICNafp, the original name is then called the basionym. Some examples:
Although the first civilian GPS receivers were developed by Magellan in 1989, they were very large and therefore impractical for animal applications. By the mid-1990s, the larger GPS manufacturing companies created GPS receivers that were smaller, more energy-efficient, and therefore more usable for animal-tracking applications.
